PFF57-502G uses a Purple 80A durometer bush and an offset bore sleeve to allow up to 0.4deg of caster increase from OE. This allows for steering pull correction or a more aggressive steering axis angle for increased steering feel and in-corner camber gain. It fits the front of all 996 and Boxster 986 models, and the front of the 997 GT2, GT3 & GT3RS models only. All other 997 models use PFF57-802G.
