01Overview
This is the rear bush of the rear subframe mount, in polyurethane.
Rubber in this position lets the back of the subframe lift under load. Rear camber and toe move while you are cornering, which is why the car feels vague at the limit.
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 geometry where the alignment rack left it — the rear stays predictable all the way to the limit.
Every StrongFlex product ships with the correct grease for fitting.

05Options & Notes
The other hardness

Fitting notes
01A car takes 2. This listing is 1 piece, so order accordingly.
02Replace them in pairs. A new bush on one side and a tired one on the other leaves the axle sitting crooked.
03Grease the bush surfaces on assembly. StrongFlex include the grease.
