Porsche 911, 996 & 997, Boxster, Caster Offset Control Arm Outer Bushings
PFF57-502G Front Track Control Arm Caster Offset Outer Bushings use our standard Purple 80A material, combined with an offset bore sleeve that allows up to a 0.4° caster increase from OE. This adjustment can help correct steering pull or provide a more aggressive steering axis angle, improving steering feel and in-corner camber gain.
These bushings fit the front of all 996 and Boxster 986 models, as well as the front of the 997 GT2, GT3, and GT3RS models. For all other 997/987 models, use part number PFF57-802.
Additionally, this part is available in our Black Series 95A durometer material for a no-compromise, track-ready option.
