Direct replacement kits: All the big brake conversion kits we retail are direct bolt on replacement kits. This means that modifications are not required to the vehicle to fit the new calipers, rotors and parts. The kits are supplied with vehicle specific caliper brackets which aid in fitment.
How long should it take to fit each kit? We estimate that 1 hour per side should be more than enough time to complete a fitment. Once you have removed the original OEM parts, the new parts will bolt straight on in their place providing your upgraded braking power.
Hi Spec - Vauxhall Astra H 300mm Billet 4 Conversion Kit
Information: This Hi Spec Motorsport 300mm Billet 4 conversion kit will fit your Vauxhall Astra H from 2004 onwards. For small to medium weight road cars, a Hi Spec Billet 4 Conversion is the ideal kit. With disc sizes ranging from 280mm to 325mm giving increased leverage, higher rotation speed of the disc relative to the pad and more surface area to assist with heat dissipation when compared with standard set ups.
Pricing: Product pricing is for a 1 complete Hi Spec 300mm Billet 4 conversion kit, (both front hubs).
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 to take braking performance into another league.
Fitting these alloy calipers and light weight one or two-piece discs has the added benefit of reducing unsprung weight. This is more important than just losing weight from the car. Losing 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.

Wheel clearance: Before ordering please check your wheel clearances. HiSpec calipers are wider than the standard sliding caliper, therefore we cannot guarantee fitment for every wheel on the market. You can check your clearances by clicking the wheel clearance diagram above. The wheel size listed is for the standard wheel.
