Our Top Recommended Big Brake Upgrade Kits For Your Nissan 300ZX
The 300ZX ran through two very different-looking generations, naturally aspirated and twin turbo engines, and both a 2-seat and a 2+2 body. None of that shows up in the brake kit listings. Every Tarox and HiSpec kit on this page is sold as a single, universal front conversion for “the Nissan 300ZX”, with no split by generation, engine or body style. That is unusual on this site, where several guides fork by generation because the kits genuinely differ. Here they do not, so the decision comes down to wheel size, caliper family and budget. The same is true for Brembo: the four front kits and three rear kits cover 1990 to 1996 as one universal fitment.
Coverage on this car spans three brands now. Tarox and HiSpec between them cover 300mm up to 340mm from £1,464 to £2,610 inc VAT. Brembo adds an aspirational tier from £3,719.68 inc VAT, all made to order in Italy with a six to eight week lead time. The full 300ZX range is on the site if you want to see everything at once.
- Every kit here converts the front axle only: calipers, two-piece discs, brackets and fitting hardware for the Nissan 300ZX
- No generation, engine or body split on this page. One listing per kit fits the whole range
- Disc sizes run from 300mm to 340mm for HiSpec and Tarox, and 332mm to 355mm for Brembo
- Tarox kits arrive with Corsa pads and braided hoses already fitted; the HiSpec kits for this car include an EBC pad as standard too, which is unusual for HiSpec
- Brembo kits start at £3,719.68 inc VAT and are made to order in Italy, six to eight weeks

Three brands, three approaches
All three brands machine their own calipers from billet aluminium and build each kit for the car. Where they differ is in what goes in the box, where the work is done, and how long you wait.
Tarox
Made at the Tarox factory in northern Italy. Calipers CNC machined from European billet alloy and hand assembled, each one tested before dispatch. Every disc is heat treated, CNC faced and hand balanced to 0.05mm. Every 300ZX kit arrives with Corsa pads pre-installed and vehicle-specific braided hoses in the box. Full ABS and ESP compatibility stated on all three kits.
HiSpec Motorsport
Machined in Dartford from billet aluminium, calipers and pistons both. Made to order in up to 28 working days, finished in your choice of black, red, blue, gold or silver. On the 300ZX specifically, every HiSpec kit we checked includes an EBC pad as standard, which is unusual for HiSpec. Braided hoses come included on the Monster kits and are optional on the Billet 4 and Mega Monster.
Brembo
Made to order in Italy, six to eight weeks. The GT caliper families run from the GT-A two-piece through the GT-M cast monobloc to the GT-S and GT-R billet options. Every kit ships with a caliper clearance drawing showing the A, B and C dimensions for that specific caliper body, which is what Cameron uses to confirm wheel fitment before anything is built. Disc face (cross-drilled or Type 3 slotted) and caliper colour are both free choices at order.
One external link worth bookmarking for Tarox: their wheel clearance template is the definitive check for spoke depth once you have the minimum diameter sorted.
The number that decides it: your wheel size
Disc diameter sets the minimum wheel, and for Tarox and HiSpec the range runs from 16 inch at the entry kit to 18 inch at the top. The HiSpec figures come straight from their own catalogue statements against each disc size. The Tarox figures were looked up individually on tarox.co.uk for each kit’s own product page. For Brembo, the minimum wheel size is not published as a single figure: every Brembo kit ships with a caliper clearance drawing showing the A, B and C dimensions for the specific caliper body, and that is what Cameron uses. A GT-R caliper sits wider behind the spoke than a GT-A on the same disc, so the drawing is what matters, not a single published diameter.
| Kit | Disc | Smallest wheel |
|---|---|---|
| HiSpec 300mm Billet 4 | 300mm | 16 inch |
| Tarox 310mm Sport | 310 x 30mm | 16 inch |
| HiSpec 325mm Monster 4 | 325mm | 17 inch |
| HiSpec 325mm Monster 6 | 325mm | 17 inch |
| HiSpec 335mm Monster 4 | 335mm | 17 inch |
| Tarox 330mm Sport | 330 x 26mm | 17 inch |
| HiSpec 360mm Monster 6 | 360mm | 18 inch |
| HiSpec 360mm Mega Monster | 360mm | 18 inch |

HiSpec 300mm Billet 4: the entry kit at 16 inch
If the car is on 16 inch wheels and you want to keep them, this is the pick. The Billet 4 is HiSpec’s most popular caliper: four pistons machined from billet aluminium with integral dust seals to keep road grit out. On a 300mm two-piece floating disc it is a genuine step over the standard setup and clears a 16 inch wheel.
The kit includes an EBC Standard Road Pad as standard, marked upgradeable, so it arrives ready to bolt on without a separate pad order. Braided hoses are listed as optional on this kit, so tell us if you want them included when you order.
- £1,464.00 inc VAT
- Clears 16 inch wheels
- 300mm two-piece floating disc
- EBC Standard Road Pad included, upgradeable; braided hoses optional
- Three caliper colours
HiSpec 325mm Monster 4 and Monster 6: the 17 inch move
Once the car is on 17 inch wheels the Monster caliper comes in. It uses a pad a third bigger than the Billet 4, built for medium to heavy cars or those carrying serious power. Both the Monster 4 and Monster 6 sit on the same 325mm two-piece disc and clear a 17 inch wheel; the difference between them is piston count and clamping force.
Both kits include an EBC Redstuff pad as standard and braided hoses in the box, so unlike the Billet 4 entry kit there is nothing extra to add. For most road-driven 300ZXs on 17s, the Monster 4 does the job. The Monster 6 is for a car that sees track use or carries more power than standard.
- Monster 4 at £1,596.00 inc VAT; Monster 6 at £1,683.00 inc VAT
- Both clear 17 inch wheels
- 325mm two-piece floating discs
- EBC Redstuff pads and braided hoses included on both
- Five caliper colours
Tarox 310mm Sport: the complete kit at 16 inches
The entry Tarox for the 300ZX, and the easiest buy on this page if you want the whole job in one delivery. Six-piston caliper on a 310mm two-piece disc balanced to 0.05mm, Corsa pads already in the calipers and braided hoses in the box. Clears 16 inch wheels, the same as the HiSpec Billet 4.
Tarox list this as one single listing for the 300ZX, not split by engine, so there is no fitment question to work through before ordering. Full ABS and ESP compatibility is stated on the kit.
- £2,094.00 inc VAT, complete with pads and braided hoses fitted
- Clears 16 inch wheels
- 310mm two-piece disc, balanced to 0.05mm
- Six-piston billet caliper, hand assembled in Italy
- One listing covers the whole 300ZX range
HiSpec 360mm Monster 6: the 18 inch track pick
The biggest Monster caliper listed for the 300ZX. Six pistons on a 360mm two-piece disc, the same Monster 6 caliper as the 325mm kit but stepped up to the largest disc HiSpec publish this caliper against for this car. It clears an 18 inch wheel.
This is the kit Cameron points people at when the 300ZX sees regular track days. The extra disc size over the 325mm and 335mm Monster kits buys more leverage and better heat dissipation, and the kit still includes the EBC Redstuff pad and braided hoses as standard.
- £1,863.00 inc VAT
- Clears 18 inch wheels
- 360mm two-piece floating disc
- EBC Redstuff pad and braided hoses included
- Five caliper colours
Tarox 340mm Super Sport: the flagship, and a title worth double-checking
The biggest Tarox kit for the 300ZX and the most complete package on this page from a Tarox perspective. Two-piece disc balanced to 0.05mm at 340mm, Corsa pads fitted at the factory and braided hoses in the box. Clears an 18 inch wheel.
Our own listing title calls this a “10pot” kit. It is not: Tarox’s own spec and our product description both state an 8-piston caliper, part code B34GT/B360, with sequential piston sizing for even pad contact. We are flagging the title for correction and are not repeating it in our own copy. Whichever number is on the page, the caliper is the 8-piston Super Sport, and it is the complete Tarox build for a 300ZX used for fast road and track.
- £2,610.00 inc VAT, complete with pads and braided hoses fitted
- Clears 18 inch wheels
- 340mm two-piece disc, balanced to 0.05mm
- 8-piston billet caliper (B34GT/B360), hand assembled in Italy
- Sequential piston sizing for even pad contact
Brembo GT range: what the price gap pays for
Brembo make four front kits and three rear kits for the 300ZX, all covering 1990 to 1996 as a single universal fitment. None of them are on a shelf waiting to go: every Brembo kit is made to order in Italy, six to eight weeks from the order date.
The four front kits ladder through the GT caliper families. The GT-A starts at £3,719.68 inc VAT: a 332mm disc with a four-piston two-piece caliper body. It is the only Brembo front kit on this page that is not a monobloc, and the easiest of the four to fit in a tight wheel package. The GT-M steps up to 355mm and a six-piston cast monobloc at £4,295.95. The GT-S sits at the same 355mm for £4,400.74 but uses a billet body rather than a casting, which is stiffer under sustained heat. The GT-R at £8,329.97 is the billet race-spec caliper, and what that price buys over the GT-S is the caliper’s ability to hold its shape when brake temperatures build through a track session.
If you want to spec the whole car at once, three rear kits follow the GT-M, GT-S and GT-R family at 345mm. Drop us an email or click to open a chat and we will put together the full front and rear combination before you order.
Wheel clearance for any Brembo kit is confirmed from the caliper clearance drawing on the product page, which shows the A, B and C dimensions for that specific caliper body. A GT-R caliper sits wider behind the spoke than a GT-A on the same disc, so the drawing is the check, not a single published diameter. Cross-drilled or Type 3 slotted is your call at order, same price either way. Caliper colour is a free option set when the order goes in.
- GT-A 332mm from £3,719.68 inc VAT; GT-R 355mm at £8,329.97 inc VAT
- Four front kits (GT-A, GT-M, GT-S, GT-R); three rear kits at 345mm
- Made to order in Italy, six to eight weeks
- Disc face (cross-drilled or Type 3 slotted) is your choice, same price
- Caliper clearance drawing on each product page; Cameron confirms spoke clearance before ordering
More options at 17 and 18 inches
Three more kits sit between the picks above and are worth knowing about. The HiSpec 335mm Monster 4 is a cheaper option to the 325mm Monster 6 at the same 17 inch wheel size, for a car that wants more disc without moving to the six-piston caliper. The Tarox 330mm Sport is the middle Tarox disc size, still all-in-one with pads and hoses fitted, and also needs 17 inch clearance. The HiSpec 360mm Mega Monster is HiSpec’s flagship caliper for this car, a six-piston design with a bigger pad than the Monster 6, and it is the most expensive HiSpec kit on the page.
What is actually in each box
The 300ZX is one of the cars where HiSpec break their usual rule. On most vehicles in this series HiSpec price pads separately, and Tarox include them fitted as standard. Here every HiSpec kit includes an EBC pad as standard, marked upgradeable, not left out. Braided hoses come with the Monster kits; on the Billet 4 and Mega Monster they are optional. Tarox includes both as standard across all three of their kits. Brembo: pads and hose inclusion follows the kit specification, and Cameron will confirm the details when the order is discussed.

Prices include VAT and were correct on 30 September 2026. The Tarox 340mm kit is listed on our site under the title “10pot”; the caliper is the 8-piston B34GT/B360, per Tarox’s own spec and our product description. Brembo kits are made to order in Italy, six to eight weeks. Brembo wheel clearance is confirmed from the caliper clearance drawing on each product page, not a single published minimum diameter.
Common questions
Does the kit differ between the older 300ZX and the later Z32 shape?
Not on this page. Neither Tarox nor HiSpec split their 300ZX kits by generation, engine or body style, so every Tarox and HiSpec kit here is listed as one universal front conversion. Brembo follow the same pattern: all four front kits are listed for 1990 to 1996 as a single fitment. If you are unsure whether a specific detail of your car changes anything, drop us an email or click to open a chat and we will check before you order.
Why does the Tarox 340mm kit say "10pot" when the spec says 8-piston?
That is a mistake in the product title on our site. The kit contents and Tarox's own published spec both describe an 8-piston caliper, part code B34GT/B360, with sequential piston sizing. The caliper itself has not changed, only the number in the title is wrong, and we have flagged it for correction.
Do the HiSpec kits on this page include pads and hoses?
Yes, which is unusual for HiSpec. Every HiSpec kit we checked for the 300ZX includes an EBC pad as standard, marked upgradeable so you can move to a different compound later. On most vehicles in this series HiSpec price pads separately, but on the 300ZX listings they are included. Braided hoses come included on the Monster 4 and Monster 6 kits. On the entry Billet 4 and the flagship Mega Monster, hoses are listed as optional.
What is the difference between the Monster 4 and Monster 6 calipers?
Piston count and clamping force. The Monster 6 uses six pistons against the Monster 4's four, on the same pad size, which HiSpec state gives up to 63% more piston area. Both sit on the same disc sizes at each step, so the choice is about how the car is driven. A road car that sees occasional track days is well served by the Monster 4; a car doing regular trackwork or carrying more power suits the Monster 6.
Are there Brembo kits for the 300ZX, and what does the caliper family range look like?
Yes. Brembo make four front kits and three rear kits for the 300ZX, all covering 1990 to 1996 as one universal fitment. The front kits ladder from the GT-A at £3,719.68 (332mm, four-piston, two-piece caliper) through the GT-M at £4,295.95 (355mm, six-piston, cast monobloc) and the GT-S at £4,400.74 (billet body at the same 355mm) to the GT-R at £8,329.97 (billet race-spec). All are made to order in Italy, six to eight weeks. Garreth's view is that a Brembo kit makes the most sense on a 300ZX that is going on circuit regularly or carrying significant engine work. Ring us and we will talk through whether the extra lead time and the price difference make sense for how the car is actually used.
Will these kits work with ABS and ESP on the 300ZX?
Tarox state full ABS and ESP compatibility on all three of their 300ZX kits. HiSpec's fitment is to the front hub and does not touch the ABS sensor or reluctor ring, so compatibility on a standard car should be fine. If your car has had any non-standard ABS work done, tell us when you order and we will check with HiSpec before the kit goes to build.
What we would actually fit
On a road car keeping its 16 inch wheels, the HiSpec 300mm Billet 4 is the honest starting point, and the Tarox 310mm Sport is the one if you want everything fitted in one delivery. On 17s, Garreth’s default is the HiSpec 325mm Monster 4: pads and hoses already in the box, and for most 300ZXs on the road that is more caliper than the car needs to prove a point.
For a car that actually sees the track, the 360mm Monster 6 is the one Cameron fits. The Tarox 340mm is there for anyone who wants the biggest Tarox disc on the page in one complete delivery, regardless of what the listing title currently says. The Mega Monster sits above both on price and is worth a phone call before ordering, because getting the pad and caliper choice right matters most on that one.
If the car is going on circuit regularly, or there is serious engine work behind it, then the Brembo GT-A at £3,719.68 is where that conversation starts. It is roughly two and a half times the HiSpec entry cost, and the six to eight week lead time is real, so plan it in. The GT-R at £8,329.97 is for a 300ZX being pushed hard on track and nothing else.
Ring us on 0115 9893488 with your current wheel size and what the car does at weekends. Because nothing here forks by generation or engine, that call is usually a short one, and checking spoke clearance on a specific wheel is Cameron’s side of the business.
