This kit is designed to add 0.5 deg. static positive caster to both front wheels while introducing a substantial amount of front anti-lift.

The low compliance bushing will also maintain higher dynamic positive castor.

By changing the front control arm geometry, the new alloy mounts coupled with the new low compliance polyurethane bushings oppose lift under power including cornering, dramatically reducing understeer and front wheel spin.

Fits: Subaru WRX STi 02-07
