Powerflex Black Series Front Lower Wishbone/Control Arm Rear Bushes (Lollipop/Caster Mount) for BMW E36 3 Series 1990-1998 with E46 Alloy Arm Swap - Polyurethane Hybrid, CNC Aluminium Outer - Fits E30/E36 Carrier - Track/Drift - PFF5-3603BLK

BMW E36 Front Lower Control Arm Rear Mounts, Polyurethane Hybrid, Alloy Shell

Transform the front end of your BMW 3 Series E36 with a serious suspension upgrade. This hybrid rear mount for the front lower arm delivers crisp steering feel, rock-solid geometry control and long-term durability for fast-road, track day and drift use. Built around a free-rotating two piece design, it pairs a tough 95A Black compound inner with a CNC-machined aluminium outer housing for exceptional rigidity under load and consistent alignment.

Engineered to accept the hex profile of the E46 aluminium lower arm while locating in the E30 and E36 carrier, this kit is a popular choice for E36 owners running the E46 alloy arm swap. The result is a precise, quiet and low-bind solution that resists oil, heat and abrasion far better than ageing rubber.

Why enthusiasts choose this kit

• Sharper turn-in and more direct steering feedback under braking and cornering
• Reduced compliance for consistent caster and camber retention
• Free-rotation inner for smooth articulation and minimal bind
• 95A Black Series polyurethane inner for motorsport-grade resilience
• CNC alloy outer shell for maximum stability in high-stress conditions

Fitment and compatibility

Suitable for BMW 3 Series E36, 1990 to 1998, when using E46 aluminium front lower control arms into E30 or E36 carriers, thanks to the inner hex interface and E30 or E36 outer dimensions.
