Will it fit my car?
This kit is built for the car named in the listing, and the generation matters: hub design, hub bell shape, and caliper bracketry are car-specific even when the disc size looks the same. If your car is near a facelift year or an unusual variant, send us the registration and we will confirm the exact kit before you order.
Will it clear my wheels?
Tarox publish a minimum wheel size per kit rather than per disc size, and the same disc diameter genuinely differs between cars in their range, so we quote it per kit rather than guessing. Ask us with the kit and your wheel details and we will confirm the published figure and check spoke clearance.
What about my handbrake?
This is a rear kit, and rear upgrades interact with the handbrake, especially electronic parking brakes, where a caliper change is not always possible. Our guide on big brake kits and electronic handbrakes covers what fits and what does not, and we will confirm for your exact car before you order.
Which pad compound should I run?
It depends on use, not on the kit: fast road, track day, and race compounds behave very differently when cold and when worked hard. Our guide on brake pad compounds explains the choices for Tarox kits in plain terms, and heading to a circuit, our track day brake prep guide covers pads, fluid, and bedding in.
What does the 6-piston caliper actually give me?
More pistons spread clamping pressure across a bigger pad more evenly, which improves pedal feel and pad wear rather than raw stopping power, and the bigger disc adds the leverage and heat capacity. The honest summary: consistency lap after lap, and a pedal you can modulate, not a party trick emergency stop.
Every brake kit here is built to order
We do not keep big brake kits on a shelf. Each one is put together for your car in the disc face, caliper colour and specification you choose when you order, so nothing is made until the order is placed. The site shows these as available because we can take the order and start it, not because it is boxed and waiting.
How long it takes
Brembo GT kits are made in Italy and run around six to eight weeks. Our UK built kits are quicker, and the exact time depends on the caliper and disc combination you pick. Ring us on 0115 989 3488 before you order and we will give you the current lead time for the kit you are looking at, not a general one.
Working to a date
If the car is booked in, or it is off the road, tell us the date when you call. We will tell you straight whether the kit will make it, and what the alternatives are if it will not.
Worth two minutes before you order
Wheel clearance catches people out. Send us your wheel make, size and offset and we will read it against the caliper clearance drawing first, because a kit that is already being built for you is not something we can simply swap.
