What does a full conversion kit do?
This full kit combines a ‘Billet-4’ 4-pot alloy caliper with large two-piece discs to give a significant increase in stopping power. The improved stopping power of the calipers join forces with the greater leverage and heat dissipation properties of the 300mm discs to take braking performance into another league.

Fitting these alloy calipers and light weight two-piece discs has the added benefit of reducing ‘unsprung’ weight. This is more important than just loosing weight from the car – loosing unsprung weight means better handling and response from dampers.

What is a ‘Billet-4’ caliper?
As its name suggests the ‘Billet-4’ caliper is CNC machined from aerospace grade billet aluminium. The result is a super-rigid caliper with almost no flex (a common problem with other alloy calipers). The ‘Billet-4’ features integral dust seals, internal fluid transfer galleries and a fully anodised finish in a choice of three colours.

What’s included?
This kit includes a pair of ‘Billet-4’ alloy calipers, a pair of grooved two-piece 300mm diameter vented discs with alloy centre bells, a pair of brake caliper relocation brackets and all necessary nuts, bolts and washers. Other items that you will need (but are not included in this kit) are a set of brake pads and braided hose lines. You may also require some brake fluid. Scroll to the bottom of this page for a link to any of these additional items.

IMPORTANT NOTE
You must check that there is enough space available behind your wheels for the disc and caliper. Two measurements are critical and you should NOT assume they will fit without checking.

Firstly, check the spoke clearance. This is the distance horizontally between the inner face of the wheel spoke and the disc face (see the relevant image on this page). You need a minimum of 60mm here. If you don’t quite have 60mm wheel spacers or shims can be used.

Secondly, check the internal diameter of your wheel. A minimum diameter of 350mm (14 inches) is required. As a general rule this kit will fit behind most 16 inch alloys and some 15 inch alloys too.

About fitting
Fitting should always be carried out by a competent individual – preferably a professional engineer.
