Powerflex BMW F20, F21 (2011-2019) Front Radius Arm F8x M Conversion Bush

• Developed for ultimate performance using the toughest materials
• Engineered for the most accurate control of chassis geometry
• Manufactured to be easily fitted without the need for special tools
• Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry.
• This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material.

• PFF5-4901BLK Front Radius Arm F8x M Conversion Bush has been designed to fit the original equipment "M" radius arms but accommodates the wider subframe fitted to non-M cars. This new bush option allows older arms with worn bushes to be repurposed, saving the cost of buying new BMW arms at around £150 to £200 each. Seen more as a track/motorsport upgrade, these parts are available exclusively through our Black Series and made in our Black 95A material, paired with stainless-steel inner sleeves and CNC-machined outer shells for strength and improved load distribution. The increase in caster provided by this conversion and the fitment of our bush allows for greater in-corner camber gain, with improved front-end grip and turn-in. This makes it an ideal upgrade for any tuned M'lite looking to head out on track, and it serves as great accompaniment for our PFF5-1902GBLK Camber Adjustable Bushes.
