What is the Subaru Impreza WRX brake conversion for standard Impreza models? rev. 990125 For those wanting to improve the performance of their standard Impreza to WRX level, the chassis responds very well to the following modifications. Front Brakes: The pre96 WRX calipers are a good value while supplies last. SPD offers these in the catalog. See Parts, Brakes. These are dual piston calipers and 10.9" vented rotors bolt on. You must use 15x6 Subaru wheels or larger to clear these brakes. Do not forget to order Mintex pads. The other way to obtain these parts in a 10.7" later design is from a late model Forester, Legacy Outback or GT. Ask for the dual piston caliper and disk. Tirerack (www.tirerack.com) has OEM 15" Subaru alloys for $59/69 each to fit these brakes. Best deal going. They are some of the lightest 15" wheels you can buy. AND they fit! For Subaru RS 2.5 owners with the RS type 16" wheels required, the latest WRX-RA STi Four Piston Calipers and 298mm rotors are a great improvement. See Parts, Brakes page. Rear Brakes: If your car already has disks, you are set unless you insist on vented rear rotors. In that case see the parts list section for WRX Vented rear rotors and the required wide caliper. These calipers are wider than standard to fit the vented rotors. Again, order Mintex pads also. For those with drum brakes in the rear, the best solution is a trip to You unbolt the brake line, plug it, unbolt your hubs, remove the axles, You now have brakes. Next stop: The suspension department. For those concerned about brake proportioning valves, master cylinders The brake proportioning valve is the same on all cars to 96, even though The ABS has a "tone wheel" and magnetic sensor on the axle with a pig |
