The stock Genuine BMW rear upper control arms (33326792543, 33326792544, 33326792539, & 33326792540) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics, not to mention insufficient adjustability.
Turner's new Performance Adjustable Rear Upper Control Arms greatly increase the range of rear camber adjustment for high-performance track/street applications and are a must for lowered cars to meet alignment requirements.
These control arms feature gun drilled 2024 Aluminum center links, clamps, and clevises, along with a 360-degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. No annoying jam nuts! A simple 3/16" Allen-key is all that is required to lock down your alignment settings.
FK Spherical Rod Ends are utilized to reduce alignment change in the rear suspension under hard cornering, acceleration, and braking. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation, and eliminate bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race, offering a very high load carrying capacity and greatly increased dynamic wear characteristics.
