Uprated Front Thrust Arm Bush Kit for BMW M5 and M6 - Part No. PFF5-6201

Transform the front-end composure of your BMW with this performance polyurethane bush kit for the forward wishbone, also known as the caster arm or compression arm. Powerflex PFF5-6201 replaces the factory hydrobushes that soften with age, keeping the wheel located under load for crisper steering, rock-solid braking stability and consistent geometry on fast road driving.

We run these on our own cars and our customers love the instant improvement in turn-in, reduced brake dive and the way the car tracks straight without tramlining. If you are refreshing the front axle on an F10 M5 or F06 F12 F13 M6, this is the go-to handling upgrade.

Why upgrade to PFF5-6201

• Direct replacement for tired OE hydrobushes that restores precision and confidence
• Holds wheel alignment during hard cornering and heavy braking for stable, predictable responses
• Minimises unwanted deflection which helps tyre wear and grip consistency
• Durable polyurethane construction that resists oil, road salt and heat for long service life
• Ideal for daily use, spirited B-road driving and track-day prep without harshness
