Super Pro Front Control Arm Inner Rear Bushing Autocross Kit 2002-2007 WRX / 2004-2007 STI

This kit is designed to add +/- 0.5 degree static caster to both front wheels. The special low compliance bushings that reduce caster wind-back and maintain tighter tolerances between static and dynamic alignment settings. The additional caster coupled with the firmer bushings serve to dramatically sharpen initial turn-in response, then forcing more consistent alignment angles through the corner due to the reduced bush compliance. This kit is called the Autocross kit because it increases static caster without changing a suspension mounting point making it legal for most Autocross classes.
