031592A: Rear subframe - front bush SPORT

This is the front bush of the rear subframe mount, in polyurethane.

This is the bush that takes the drive load. Worn rubber here shows up as a clunk on the throttle and a rear end that squats and steps out of line under power.

90 ShA polyurethane — the yellow SPORT compound. StrongFlex build this grade for tuned and lowered cars: the suspension gets noticeably stiffer, the geometry stops moving under load and the car holds its line when you push it.

Polyurethane holds the subframe still, so the power goes to the road instead of into flexing rubber.

Every StrongFlex product ships with the correct grease for fitting.
