Rear Upper Arm Function on the Evo 8/9
The rear upper control arm is the primary camber link in the Evo 8/9 rear suspension. All of its bushing positions — inner front, inner rear, and outer — contribute to maintaining consistent rear camber through suspension travel. The W0591 kit covers all of these positions simultaneously for a complete upper arm rebuild.

Evo Competition Use
On an Evo used for time attack or circuit driving, rear camber consistency is directly related to rear grip repeatability. Complete upper arm bushing replacement is a standard part of any serious Evo rear suspension rebuild.

Complete Kit for Efficiency
All upper arm bushing positions in one purchase means one order, one installation session, and a fully rebuilt rear upper arm.
