Why choose this mount set

Factory rubber softens and splits with age, which leads to clunks, imprecise rear end behaviour and wasted power. The Powerflex compound maintains control without a big increase in cabin harshness, giving you consistent response and confidence when you lean on the car. It is a fit-and-forget upgrade that stands up to daily use and spirited driving.

What is included

• 2 x Powerflex bushes for the final drive front mounting point
