Our Top Recommended Big Brake Upgrade Kits For Your Honda S2000
The S2000 ran from 1999 to 2009 across two chassis codes, AP1 and AP2, the AP2 picking up the bigger 2.2 litre engine and a revised suspension setup partway through. You would expect a brake catalogue to split by generation the way it does on plenty of other cars in this series. It doesn’t here. Every Tarox and every HiSpec kit on this page lists as one “Honda S2000” fitment, not a version each, so the kit that fits an early AP1 fits a late AP2 too.
Nine kits qualify once Brembo and K Sport are set aside, which is thinner than some of the cars we’ve covered in this series, and we’d sooner say that plainly than pad the page out. Tarox contribute three, HiSpec six, and all nine are front kits. HiSpec also sell a genuine rear conversion for the S2000, a 300mm Ultralite 2 kit that clears 13 inch wheels, which is unusual enough in this series to mention: if you’re doing both ends, ring us and we’ll spec the pair together. The full S2000 range is on the site if you want to browse it raw.
- Every kit on this page converts the front axle; a genuine HiSpec rear kit exists separately for the S2000 if you're doing both ends
- Tarox and HiSpec each list the S2000 once, not split between AP1 and AP2
- Wheel sizes on this page run from 16 inch to 18 inch, all real published figures
- Tarox kits arrive with Corsa pads and braided hoses fitted; HiSpec price those separately
What is on this page
Two brands, two ways of building a brake kit
Both companies machine their own calipers from billet aluminium and build each kit for the specific car. The difference comes down to two things: what is in the box, and where the work is done.
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, faced and balanced to 0.05mm. All three S2000 kits arrive complete with vehicle-specific braided hoses and Corsa pads already fitted, and Tarox state full ABS and ESP compatibility on every one.
HiSpec Motorsport
Machined in Dartford from 6082 T6 billet aluminium, calipers and pistons both. Every kit is made to order in up to 28 working days, with the calipers finished in your choice of black, red, blue, gold or silver. Pads and braided hoses are priced separately so you choose the compound for the way the car is used.
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
On the S2000 the range runs from 16 inch at the smallest kit to 18 inch at the biggest, so nobody on this car is starting from a 15 inch wheel. HiSpec publish the wheel size for every kit from their own catalogue. The three Tarox figures were looked up individually on tarox.co.uk against each kit’s own KM code, never assumed from the disc size, because Tarox’s own data shows the same diameter can carry a different minimum on a different car.
| Kit | Disc | Smallest wheel |
|---|---|---|
| HiSpec 300mm Billet 4 | 300mm | 16 inch |
| HiSpec 315mm Monster 4 | 315mm | 16 inch |
| Tarox 315mm Sport | 315 x 26mm | 16 inch |
| HiSpec 335mm Monster 4 | 335mm | 17 inch |
| HiSpec 335mm Monster 6 | 335mm | 17 inch |
| Tarox 330mm Super Sport | 330 x 24mm | 17 inch |
| HiSpec 360mm Monster 4 | 360mm | 18 inch |
| HiSpec 360mm Monster 6 | 360mm | 18 inch |
| Tarox 340mm Super Sport | 340 x 26mm | 18 inch |
HiSpec 300mm and 315mm: the 16 inch entry point
The smallest disc HiSpec list for the S2000 is 300mm, on their Billet 4 caliper, and it clears a 16 inch wheel. Four pistons machined from 6082 T6 billet aluminium, a two piece floating disc, and a proper step over the standard setup for a road car that isn’t chasing lap times.
Sit the 315mm Monster 4 alongside it and something worth flagging shows up: it’s £99 cheaper than the 300mm Billet 4, despite the bigger disc and the higher-tier caliper. HiSpec’s own description says the Monster 4 pad is a third bigger than the Billet 4’s and suits a heavier or more powerful car better, so you’re getting a better caliper on a bigger disc for less money, plain and simple. If the budget stretches to either, the 315mm Monster 4 is the one Garreth would put the money on.
- £1,464.00 inc VAT (300mm Billet 4); £1,365.00 inc VAT (315mm Monster 4), the bigger disc is the cheaper kit
- Both clear 16 inch wheels
- Four piston calipers on both, Billet 4 or Monster 4
- Pads and hoses priced separately; five caliper colours
- Made to order in up to 28 working days in Dartford
Tarox 315mm Sport: the complete kit at 16 inches
The entry Tarox for the S2000, and the easiest buy on this page if you want the whole job in one delivery. Six piston B32 caliper on a 315 x 26mm 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 both HiSpec options above.
It costs more than either HiSpec 16 inch kit, £2,045 inc VAT against £1,365 to £1,464. That gap is mostly the pads and hoses HiSpec price separately, which narrows things once you spec a HiSpec kit up to match. Tarox state full ABS and ESP compatibility on this kit, worth knowing if the car has had any driver aids added since 1999.
- £2,045.00 inc VAT, complete with Corsa pads and braided hoses fitted
- Clears 16 inch wheels
- 315 x 26mm two piece disc, balanced to 0.05mm
- Six piston B32 billet caliper, hand assembled in Italy
- ABS, ESP and modern driver aids compatible, stated by Tarox
HiSpec 335mm Monster 4 and Monster 6: the 17 inch step up
Both the Monster 4 and Monster 6 sit on a 335mm two piece disc and both clear a 17 inch wheel. The difference is piston count and, by HiSpec’s own figures, up to 63% more piston area on the Monster 6 for the same size pad. More clamping area for a given pad footprint means more bite before the pad runs out of grip.
For an S2000 that sees the odd track day the Monster 4 does the job and keeps pad choice simple. The Monster 6 is for a car making real power or spending a lot of time at the limit. It costs £123 more than the Monster 4 here, and that £123 buys the extra piston hardware.
- Monster 4 at £1,650.00 inc VAT; Monster 6 at £1,773.00 inc VAT
- Both clear 17 inch wheels
- 335mm two piece floating discs
- Monster 6 carries up to 63% more piston area than Monster 4
- Pads and hoses priced separately; five caliper colours
Tarox 330mm Super Sport: mind the title
The title on this kit says 10pot. It isn’t. Tarox’s own spec for the caliper fitted here lists a B34GT/B360, an 8 piston design, and that’s what actually ships. We’d sooner say so here than have you counting pistons when the box turns up. Eight pistons with sequential sizing still gives an even pad contact and a good pedal feel; it’s a strong kit on its own terms, just not the ten the name promises.
Disc is 330 x 24mm, two piece, balanced to 0.05mm, and it clears a 17 inch wheel, the same as the HiSpec Monster pair above. Pads and braided hoses are fitted, and Tarox state ABS and ESP compatibility here too.
- £2,365.30 inc VAT, complete with Corsa pads and braided hoses fitted
- Clears 17 inch wheels
- 330 x 24mm two piece disc, balanced to 0.05mm
- Caliper is a B34GT/B360, 8 piston. The "10pot" in the title is wrong, don't order expecting ten
- ABS, ESP and modern driver aids compatible
Tarox 340mm Super Sport: the biggest kit on this page
The flagship for the S2000. Same B34GT/B360 8 piston caliper as the 330mm kit above, also titled 10pot on the product page, also 8 in reality. Where it earns the flagship spot is the disc: 340 x 26mm, the biggest on this page, and the only kit here that asks for an 18 inch wheel.
For an S2000 that carries real power or sees serious track time, this is the kit that suits the rest of the build. At £2,610 inc VAT it’s also the most expensive option in the guide, and the most complete: pads and hoses fitted, nothing left to add before it goes on the car.
- £2,610.00 inc VAT, complete with Corsa pads and braided hoses fitted
- Clears 18 inch wheels
- 340 x 26mm two piece disc, balanced to 0.05mm
- Same B34GT/B360 8 piston caliper as the 330mm kit, titled 10pot on both, isn't
- The biggest disc and the biggest wheel requirement on this page
Two more options at 18 inches, and a pricing quirk worth knowing
HiSpec also reach 360mm at the top of their S2000 range, in the same Monster 4 and Monster 6 calipers already covered at 335mm. The Monster 6 prices the way you’d expect: £1,863 inc VAT at 360mm against £1,773 at 335mm, more disc for more money. The Monster 4 doesn’t. At £1,635 inc VAT, the 360mm Monster 4 is £15 cheaper than the 335mm Monster 4 three sections back, despite the bigger disc and the same caliper. If the Monster 4 is the plan at all, go straight to the 360mm: more kit for less money.
What is actually in each box
The headline prices sit further apart than the finished builds do once you spec them level. Add pads and braided hoses to the HiSpec side and the gap with the Tarox kits narrows. Compare finished builds, not the headline numbers.

|---|---|---|
| Calipers | Billet 4 or Monster, 6082 T6 billet aluminium | B32 or B34GT/B360, billet alloy, hand assembled in Italy |
| Discs | Two piece floating, with mounting bells | Two piece floating, balanced to 0.05mm |
| Brackets and hardware | Included | Included |
| Braided hoses | Priced separately | Included |

Prices include VAT and were correct on 16 August 2026. The HiSpec 360mm Monster 4 is genuinely cheaper than the 335mm Monster 4 above it in the table, not a typo. Both Tarox kits marked 8 piston carry “10pot” in their product title; the maker’s own spec sheet is what we’ve quoted here.
Common questions
Does one kit fit both the AP1 and the AP2?
Yes. Tarox and HiSpec each list the S2000 as one fitment across both chassis codes, not a separate version for the 1999-2003 AP1 and the 2004-2009 AP2. If your S2000 is either generation, the kit numbers on this page apply. If you're not certain which you have, ring us on 0115 9893488 and we'll confirm before you order.
Are the Tarox "10pot" kits really only 8 piston?
Yes, on the 330mm and 340mm Super Sport kits. The product titles say 10pot, but Tarox's own spec sheet lists the caliper fitted as a B34GT/B360, which is an 8 piston design. We've quoted 8 piston throughout this page because that's what Tarox's own data says and what actually ships. It's a strong caliper either way, just not a ten.
Why is the 315mm HiSpec Monster 4 cheaper than the smaller 300mm Billet 4?
They're different caliper families, not the same caliper on a bigger disc. The Monster 4 has a pad a third bigger than the Billet 4's and, by HiSpec's own description, suits a heavier or more powerful car better. On the S2000 it happens to be listed cheaper than the smaller Billet 4 kit: a better caliper, at a lower price.
Why is the 360mm Monster 4 cheaper than the 335mm Monster 4?
We flagged this because it looks wrong and isn't a typo. HiSpec price the 360mm Monster 4 at £1,635 inc VAT against £1,650 for the 335mm Monster 4, so the bigger disc costs less. If you're choosing between those two, the 360mm is the sensible pick regardless of budget: more disc for less money. The Monster 6 pair doesn't have this quirk and prices the way you'd expect.
Is there a rear brake kit for the S2000 as well?
Yes. HiSpec sell a 300mm Ultralite 2 rear conversion for the S2000 that clears a 13 inch wheel, separate from every kit on this page. It isn't covered here because this guide is about front kits, but if you want a matched front and rear setup, call us on 0115 9893488 and we'll spec both ends together so the brake bias stays correct.
What we would actually fit
On 16s and keeping the budget sensible, Garreth’s pick is the HiSpec 315mm Monster 4: bigger disc, better caliper, and it undercuts the smaller Billet 4 on price. If the whole job in one delivery matters more than the headline number, the Tarox 315mm Sport does that at 16 inch with pads and hoses fitted.
For a car on 17s that sees track time, the Monster 4 is what Cameron fits as the default, and the Monster 6 is there for anything making serious power. If you’re set on a Tarox at that size, the 330mm Super Sport is the pick, just go in knowing the caliper is 8 piston, not 10. On 18s the maths favours the HiSpec 360mm Monster 4 over its own smaller sibling, and the Tarox 340mm Super Sport is the biggest, most complete kit on the page if one delivery with nothing left to add is what you want.
Ring us on 0115 9893488 with which generation your S2000 is, the current wheel size, and what the car does at weekends. Checking spoke clearance on a specific wheel is Cameron’s side of the business, and if you want the rear doing at the same time we’ll spec both ends together. Most calls like this are done inside five minutes.
