Our Top Recommended Big Brake Upgrade Kits For Your Honda CRX
Ring us about brakes for a CRX and the first thing we ask is not what year it is. We ask for the chassis code off the V5, because the two brands we stock for this car do not agree on how to tell one CRX from another. HiSpec sort theirs into two lists, 242 and 262. Tarox sort theirs by chassis code. Pick off the model name alone and you have a decent chance of buying the wrong brackets.
Below are the kits we would actually fit, from Tarox in northern Italy and HiSpec Motorsport in Dartford. The full Honda CRX range is on the site if you want to browse it raw.
- Nothing in the CRX range clears a 15 inch wheel, so the original wheels are coming off whichever kit you pick
- HiSpec list the car as 242 or 262 and do not explain the number anywhere on the listing
- The 242 list gets three kits, the 262 list gets nine, and every Monster kit is 262 only
- Three kits on this page are priced below smaller kits in the same range, and all three are called out below

The two brands we stock for the CRX
Both machine their own calipers from billet aluminium and build every kit for the specific car it is going on. Coverage on the CRX is even for once: HiSpec bring twelve listings from 300mm up to 360mm across three caliper families, Tarox bring three disc sizes in nine listings.
HiSpec Motorsport
Machined in Dartford from 6082 T6 billet aluminium, calipers and pistons both. Twelve listings cover the CRX across the Billet 4, the Monster 4 and the Monster 6, from 300mm to 360mm. Every kit ships with EBC road pads, DOT 5.1 fluid and braided hoses in the box. Made to order in up to 28 working days, caliper finished in black, red, blue, gold or silver.
Tarox
Built at the factory in northern Italy. Calipers are CNC machined from European billet alloy and hand assembled, discs heat treated and hand balanced to 0.05mm. Three disc sizes for the CRX at 306mm, 318mm and 326mm, all on the six piston B32 caliper and all badged RoadRace. Corsa pads arrive already fitted and the braided hoses are cut for the car.
Which CRX have you got, twice over
HiSpec split their CRX range into two lists. One is named 242, the other 262. The number is not a year and not a trim, and no HiSpec listing on our site explains it. We have gone looking and HiSpec do not publish a CRX application table either, so we are not going to guess at it in print and have you order off our guess.
What we can tell you is what sits under each. The 242 list runs to three kits, the 300mm, 310mm and 325mm Billet 4. The 262 list has those same three plus all six Monster kits, nine in total. So every Monster caliper and every disc above 325mm belongs to the 262 cars only. If you are on the 242 list, the 325mm Billet 4 is your ceiling.
Tarox ignore all of that and sort by chassis code instead. Their three kits are listed against the Esi EH61 and Vti EG21 cars, and on Tarox’s own site each one also carries a second listing against an EE series car, a different code per kit. Our titles do not match Tarox’s on that second set, so treat the EE labels in our product names as unreliable and ring before ordering one.
Wheel sizes for every kit
Every figure below is HiSpec’s or Tarox’s own published minimum, not our estimate. The three Tarox figures were looked up from their site per kit for this guide. Read the bottom line first: the smallest number in the table is 16 inch. There is no CRX kit here that clears a 15.
| Kit | Disc | Caliper | Smallest wheel |
|---|---|---|---|
| HiSpec 300mm Billet 4 | 300mm, 2P | Billet 4, road | 16 inch |
| Tarox 306mm 6 pot | 306 x 26mm, 2P | B32-6, 6 piston | 16 inch |
| HiSpec 310mm Billet 4 | 310mm, 2P | Billet 4, road | 16 inch |
| Tarox 318mm 6 pot | 318 x 26mm, 2P | B32-6, 6 piston | 17 inch |
| HiSpec 325mm Billet 4 | 325mm, 2P | Billet 4, road | 17 inch |
| HiSpec 325mm Monster 4 / 6 | 325mm, 2P | Monster, road | 17 inch |
| Tarox 326mm 6 pot | 326 x 26mm, 2P | B32-6, 6 piston | 17 inch |
| HiSpec 335mm Monster 4 / 6 | 335mm, 2P | Monster, road | 17 inch |
| HiSpec 360mm Monster 4 / 6 | 360mm, 2P | Monster, road | 18 inch |
Three prices that run backwards
On most cars the range ladders neatly and the biggest disc costs the most. The CRX range does not, in three places, and all three are worth knowing before you spend.
The 310mm Billet 4 is £1,130.00 inc VAT. The smaller 300mm Billet 4, same caliper, same box, is £1,464.00. That is £334 more for 10mm less disc. Second, the 360mm Monster 4 at £1,635.00 undercuts the smaller 335mm Monster 4 at £1,740.00. Third, the 325mm Monster 6 at £1,683.00 also undercuts that 335mm Monster 4, so the smaller disc buys you two extra pistons and saves money at the same time.
We have checked all three against the store more than once and those are the published figures. The 335mm Monster 4 loses on price to a bigger kit and to a better caliper, so it is the one kit in the range we would not order today, and we have not picked it below.
HiSpec 310mm Billet 4: the cheapest kit on the page
The way in, and it happens to be the biggest of the three Billet 4 discs as well as the cheapest. Two piece 310mm disc on aluminium bells, four piston Billet 4 caliper CNC machined from billet aluminium with integral dust seals and internal fluid galleries. It fits behind a 16 inch wheel, which is the smallest wheel anything in this range will go behind.
It is listed on both the 242 and the 262 side at the same price, so this one is available to you whichever CRX you have got. Garreth’s view: while it is priced where it is, there is no argument for the 300mm kit at £334 more, and this is the kit we would put on a fast road CRX without thinking hard about it.
- £1,130.00 inc VAT, the cheapest kit in the CRX range
- Fits behind 16 inch wheels
- 310mm two piece disc, four piston Billet 4 caliper
- Listed for both the 242 and the 262 cars at the same price
- EBC road pads, DOT 5.1 fluid and braided hoses in the box

The biggest disc HiSpec build on the road Billet 4 caliper for this car, and the last kit available to both lists. If you are on the 242 side, this is the top of your range, and it is a proper step up in leverage over the 310mm for £340 more. It wants a 17 inch wheel.
It also costs almost exactly what the smaller 300mm kit costs, £1,470.00 against £1,464.00. Six pounds for 25mm more disc. Between those two there is nothing to think about.
- £1,470.00 inc VAT
- Fits behind 17 inch wheels
- 325mm two piece disc, four piston Billet 4 caliper
- Listed for both the 242 and the 262 cars, and the largest kit a 242 car can have
- EBC road pads, DOT 5.1 fluid and braided hoses in the box
Tarox 306mm 6 pot: six pistons on a 16 inch wheel
The entry point into Tarox on this car, and the only way to get a six piston caliper behind a 16 inch wheel. The B32-6 is hand assembled and individually tested in Italy, on a 306mm two piece floating disc balanced to 0.05mm. Corsa pads arrive already fitted and the braided hoses are cut for the car, so it goes on complete.
It is dearer than the HiSpec kits, and on this car the usual argument for that gap is weaker than normal, because HiSpec include pads, fluid and hoses on the CRX listings too. So compare these more or less like for like. What you are paying the extra for here is the six piston caliper and the Italian two piece disc, not for the contents of the box.
- £1,882.67 inc VAT, complete
- Fits behind 16 inch wheels, looked up from Tarox per kit
- 306mm two piece floating disc, balanced to 0.05mm
- Six piston B32-6 caliper, confirmed against Tarox's own spec
- Corsa pads pre-fitted, vehicle specific braided hoses included

£1,596.00 Incl. VAT£1,330.00 Excl. VAT Select options
Same 325mm disc, two different calipers, and the point where the CRX range stops being about disc size and starts being about pad area. The Monster pad is roughly a third longer than the Billet 4’s with more piston area behind it, which is what you want when the car is stopping hard over and over again.
Between the two, the Monster 6 carries more piston area for the same pad, and that shows up as pedal feel more than as a shorter stopping distance. On a road CRX the Monster 4 is plenty of caliper for a light car. On one doing regular track days, the Monster 6 at £1,683.00 is the one we would order, and it costs less than the 335mm Monster 4 anyway. Both are 262 listings only.
- Monster 4 at £1,596.00, Monster 6 at £1,683.00, both inc VAT
- Both fit behind 17 inch wheels
- 325mm two piece discs, four or six piston Monster caliper
- Listed for the 262 cars only, like every Monster kit here
- EBC road pads, DOT 5.1 fluid and braided hoses in the box
Tarox 326mm 6 pot: the top of the range
The largest Tarox kit for the CRX and the dearest thing on this page. Same six piston B32-6 caliper as the 306mm, same RoadRace build, on a bigger 326mm two piece floating disc, behind a 17 inch wheel. On a car as light as a CRX this is more brake than the road ever asks for, which makes it a track and hillclimb kit more than a fast road one.
One note on the number. Our listings call this a 325mm kit. Tarox publish 326mm for the same part number on their own site, and the maker’s figure is the one we go with, so we have written 326mm here and flagged our listing for correction. It makes no difference to the wheel size, which is 17 inch either way.
- £2,128.20 inc VAT, complete
- Fits behind 17 inch wheels, looked up from Tarox per kit
- 326mm two piece floating disc, six piston B32-6 caliper
- Corsa pads pre-fitted, vehicle specific braided hoses included
- Disc styles F2000, Sport Japan, C83 or D95, five caliper colours

If the car is still on its original wheels
This is the part most CRX owners do not want to hear. A standard car is on 13, 14 or 15 inch wheels, and the smallest kit in this range needs a 16. There is no version of this upgrade that leaves the original wheels on the car, so budget for wheels and tyres alongside the brakes. Finding that out after the kit has landed is an expensive way to learn it.
If you are moving to 16s, these three are the whole of your choice. Two of them are the same HiSpec kit listed once per CRX list, and the third is the Tarox. Everything else on this page needs a 17 or an 18.

What is actually in each box
On most cars this section is where HiSpec and Tarox separate, because HiSpec normally leave pads and hoses out so you can pick your own compound. The CRX listings are the older style that include them, so for once the two brands arrive at your door in much the same state. That makes the price comparison on this page unusually honest: what you see is close to what you pay.
| In the box | HiSpec | Tarox |
|---|---|---|
| Calipers | Billet 4, Monster 4 or Monster 6, 6082 T6 billet | B32-6 six piston, hand assembled and tested |
| Discs | Two piece on aluminium bells, straight vane | Two piece floating, balanced to 0.05mm |
| Brackets and hardware | Included | Included |
| Braided hoses | Included | Included, cut for the car |
| Pads | EBC road pads, upgradeable | Corsa pads, already fitted |
| Brake fluid | DOT 5.1 | Not included |
| Caliper finish | Black, red, blue, gold or silver | Black, red, blue, green or gold |

Prices include VAT and were correct on 15 August 2026. Tarox minimum wheel sizes and the 326mm disc figure were looked up from their own product pages per kit, HiSpec figures from their published wheel clearance statements. Sorted by price so the three backwards steps are easy to see.
Common questions
Can I fit any of these and keep my 15 inch wheels?
No. The smallest published minimum across all twenty one CRX kits is 16 inch, on the HiSpec 300mm and 310mm Billet 4 and the Tarox 306mm. There is nothing in the range that goes behind a 15, so wheels need to be part of the budget. Ring us before you buy either half of that and we will make sure the wheel you have picked clears the caliper at the spokes as well as on diameter.
What do the 242 and 262 numbers on the HiSpec listings mean?
Honestly, we do not know for certain, and neither the listing nor HiSpec's own site explains it. What we do know is which kits sit under each: 242 gets the 300mm, 310mm and 325mm Billet 4, and 262 gets those three plus all six Monster kits. We would sooner not guess at it. Ring us with the chassis code off your V5 and Cameron will confirm the right list with HiSpec before you order.
Is the 310mm kit really cheaper than the 300mm one?
It is, on our store today: £1,130.00 against £1,464.00, both inc VAT, for a bigger disc in the same caliper family with the same contents in the box. We have flagged it internally because it looks like a pricing error. If it is corrected, the price on the product page is the one that stands, so buy from that and not from this page.
The Tarox kits say 6pot in the title. Is that the real piston count?
Yes, on these three. We check this on every guide because titles and calipers do not always agree across the catalogue, and on the CRX kits Tarox give the caliper as the B32-6 on all three, which is a genuine six piston caliper. The only number we would not take at face value here is the disc size on the biggest kit, which our listing calls 325mm and Tarox call 326mm.
How long before it arrives?
HiSpec kits are made to order in Dartford, so allow up to 28 working days. Tarox kits are built for the specific car in Italy and lead times move through the year, so ask when you place the order and we will give you the current picture. The CRX is an old car and neither brand keeps these on a shelf.
What we would actually fit
On a fast road CRX moving to 16 inch wheels, the 310mm Billet 4, while it is priced where it is. Going to 17s, the 325mm Billet 4 if you are on the 242 list, or the 325mm Monster 6 if you are on the 262 list and the car sees track days, because it costs less than the 335mm Monster 4 and gives you more caliper. If you would rather have the Italian six piston and a floating disc, the Tarox 306mm on 16s or the 326mm on 17s. We would leave the 335mm Monster 4 alone until its price is fixed, and the 360mm kits to cars already on 18 inch wheels for other reasons.
Ring us on 0115 9893488 with your chassis code and the wheels you are running, or planning to run. Matching a CRX to the right list and checking a wheel will clear at the spokes is Cameron’s corner of the business, and Garreth will tell you straight whether the step up in kit is worth the money on the car you have got.
