The Billet 4 is Hi Spec’s most popular four piston caliper. The body and pistons are machined from 6082 T6 billet aluminium, with external dust boots to keep dirt out, so it needs very little looking after on a road car. This kit uses the radial mount version of the caliper.

A bolt-on front big brake conversion for the Ford Cortina Mk3, Mk4 and Mk5, built around 310mm x 28mm two piece discs on alloy bells and the Billet 4 Radial caliper. Minimum wheel size is 16 inch, and as always check your own wheels clear the caliper before ordering.

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.
