Why this upgrade works

Factory rubber mounts can squash and allow unwanted movement, softening turn-in and knocking alignment out under load. Powerflex polyurethane controls deflection so your front axle stays where you set it. You get crisper response, more consistent feedback and the ability to fine-tune camber for improved cornering stability and better tyre wear across the tread.

Real-world benefits

• Clean, direct steering with noticeably tighter turn-in
• More stable braking and mid-corner confidence
• Alignment you can trust, helping reduce uneven tyre wear
• Ideal for daily driving and spirited fast-road use

Proven by us and our customers

We run these bushes on our own cars and the feedback from owners mirrors our experience. The car feels more planted without harshness, with geometry that stays true when you lean on it.

Looking for non-adjustable?

Prefer a fixed-geometry option for a straightforward refresh. Choose the non-adjustable version PFF5-1902.
