031517B: Front wishbone bush - centric 66mm

This is the front wishbone / lower arm bush, in polyurethane.

This bush sets the front geometry. When the rubber goes soft, caster and camber move under braking and the steering goes numb exactly when you need it to talk to you.

80 ShA polyurethane — the red street compound. Firmer and far longer-lived than the factory rubber, but soft enough that the car stays civil on a bad road. This is the grade for a daily driver.

Polyurethane keeps the arm located, so the front end stays sharp under braking and turn-in and the steering tells you what the tyre is doing.

Every StrongFlex product ships with the correct grease for fitting.
