Complete Performance Polyurethane Differential And Subframe Bushing Set - E8x, E9x

Product Details

A loose rear subframe is the enemy of speed. When you step on the gas, the factory rubber bushings deflect, causing your differential to twist and your subframe to walk. The result is a loss of horsepower and 

This complete upgrade package is designed to put an end to steering slop. Utilizing a high performance 95A durometer polyurethane formulation, this kit replaces the mushy OEM rubber with proven rigidity. By tying the subframe and differential securely to the chassis via CNC machined 6061-T6 aluminum inserts and heavy duty poly isolators, you get a solid, direct connection to the pavement without the brutal cabin drone of solid metal race mounts.

Why Upgrade:

• Eliminates drivetrain "wind up," directing raw horsepower straight to the rear tires instead of wasting it compressing soft rubber.

• Keeps your rear suspension geometry locked under heavy cornering loads, giving you the confidence to slide the rear end or clip the apex.

• Factory hydraulic and rubber mounts are known to degrade and leak in as little as 30,000 miles. This polyurethane setup resists salt, and road chemicals for a lifetime of hard driving.

• Ideal for hard driven street cars, weekend track weapons, and dedicated autocross builds that demand maximum composure.
