SPL Parts 2020+ Toyota GR Supra (A90) / 2019+ BMW Z4 (G29) Rear Upper Lateral Links
Our SPL Parts TITANIUM Series Rear Upper Arms (RUA) 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. The adjustment range provided by the eccentric washer on the OEM control arm is insufficient to get camber back into proper spec.
Our Rear Upper Links feature gun drilled 2024 Aluminum center links, clamps, and clevises, along with Blue Anodized Titanium socket head cap screws and our 360 degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings oriented correctly. A simple 3/16" allen key is all that is required to lock down your alignment settings!
FK Spherical Rod Ends eliminate the soft worn out bushings on the stock links 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 eliminates bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics. The operating temperatures of the liner ranges from -65º to 325ºF, offering robust reliability for both street and track use.
