PFF5-5601M3BLK, BMW E46 3 Series M3 Front Wishbone Rear Bush, Aluminium Outer, This part replaces original bush part number: 31122229857 and fits into original bracket part numbers: 31122229623, and 31122229624, fits M3 vehicles that have a thicker wishbone. PFF5-5601M3 is a high performance option to PFF5-4601M3, and aimed at offering greater precision for people wanting the very best from their E46 M3. This new part, fitted to the rear of the front wishbone has a hard anodised aluminium outer shell with one of our unique low friction polyurethane centre bushes. The poly/alu combination creates a low friction rotating bush reducing the forces acting on the arm. Lower arm deflection has been decreased by reducing the compliant material within the aluminium shell. Results are less movement in the arm under cornering and braking, improving steering control and feel. For the M3 models which have a thicker wishbone. Please ensure you have the correct size bush before fitting. 60mm, 2 stuk(s) benodigd per auto, 2 stuk(s) in verpakking, prijs per set van 2 stuk(s)
