SuperPro Front Lower Inner Rearward DuroBall Control Arm Bushing Kit +Caster – 2015-2021 Subaru WRX/STI

Description:

DuroBall Technology for Precise Control Arm Movement

SuperPro's DuroBall bushings use a spherical bearing design rather than a traditional rubber or polyurethane bushing, virtually eliminating the deflection that comes with compressible materials while still allowing the control arm to articulate properly through its range of motion.

Added Caster Adjustment

Beyond eliminating bushing deflection, this kit's design allows for additional positive caster adjustment useful for drivers chasing sharper steering feel and improved high-speed stability on the front lower control arm's inner-rearward position.

• Front lower inner rearward control arm bushing kit
• DuroBall spherical bearing design eliminates bushing deflection
• Allows additional positive caster adjustment
• Fits the 2015-2021 WRX and STI

The RallySport Take

A serious handling upgrade for a 2015-2021 WRX or STI that's being set up for track use DuroBall bushings are about as far from a comfort-oriented rubber bushing as you can get, in a good way for outright precision.
