Powerflex Track Front Wishbone Rear Bush & Bracket - E46 3 Series inc Touring - PFF5K-4601BLK

PFF5K-4601BLK is the go-to front control arm rear-position bushing kit with carriers for BMW enthusiasts who want sharper steering, predictable turn-in and rock-solid geometry on fast road and track. This Black Series spec polyurethane upgrade transforms the front end response on BMW 3 Series E46 and BMW Z4 non-M, delivering tight, direct feedback and long-term durability that rubber simply cannot match.

Pre-assembled in brand new carrier brackets, this kit removes the hassle of pressing out old parts. No need to measure your original lollipop housings for 60 or 66 mm variants. Just bolt the new carriers onto the arm and refit to the chassis. It is quick, clean and confidence-inspiring.

• Huge handling gain with reduced deflection under braking and cornering
• Faster steering response and improved straight-line stability
• Motorsport-grade Black Series polyurethane for maximum control
