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 replaces the factory cast iron front calipers on the Ford Fiesta Mk6 with Billet 4 calipers on new mounting brackets. It runs on the ST150’s 278mm x 24mm front discs, which are not included. The ST150 already has them; every other Mk6 needs a pair of 278mm x 24mm discs as well. Minimum wheel size is 15 inch, and as always check your own wheels clear the caliper before ordering.
