    SKU: SPL TRE G29

    SPL Parts Front Tie Rod Ends (TRE) allow the tie rod end pivot to be relocated, which will correct bump steer resulting from modified caster or lower arm geometry, thus reducing lap times. On cars that are lowered significantly, relocating the pivot point will also keep the tie rod end from binding, thereby preventing the inner tie rods from breaking or bending when racing.

  • SPL Parts 2020+ Toyota Supra 2019+ BMW Z4 G29 Eccentric Lockout Kit for Rear Toe Arms
    SKU: SPL EL G29

    The stock eccentric bolts provided by BMW and Toyota for small toe and camber adjustments tend to slip under high cornering loads, causing changes to the rear alignment. Our SPL Parts Eccentric Lockout (EL) kit eliminate the stock eccentric bolts to keep your rear alignment where you set it. You must have adjustable control arms in order to adjust toe after eliminating the stock eccentric bolts. Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with zinc plated grade 10.9 bolts and lock nuts for absolutely zero-slip. This kit includes washers and bolts for both camber and toe arms. Sold as a complete kit for one car.Made in the USA.

  • SPL Parts 2021+ BMW G80 M3/ G82/G83 M4 / G87 M2 Adj Rear Upper Camber/Lateral & Upper Traction Links
    SKU: SPL RUA G8X

    BMW G8X adjustable Rear Upper Arms (RUA) are an absolute necessity to maintain proper rear camber and reduce tire wear on the street and track. The stock BMW setup has an aggressive camber curve through bump travel, which is very apparent on lowered cars. Excess negative camber causes premature tire wear on the inside edge, and reduced traction on acceleration while too little camber will limit rear grip while cornering. Our Rear Upper Arms provide a wide adjustment range for precise rear camber alignment that is easily optimized for street or track driving while eliminating bushing deflection with smooth articulating Teflon lined rod ends in place of the soft factory rubber bushings. Our kit replaces the factory links commonly referred to as the rear wishbone and rear guide links.

    BMW G8X Rear Upper Arms include gun drilled 6061-T6 Aluminum traction links to reduce weight, as well as a 6061-T6 Billet Aluminum curved rear upper camber arm that are Black Anodized to prevent corrosion and provide a durable finish. Our exclusive 360 degree 6061-T6 Aluminum Rotating Clamp design allows for quick, precise adjustment on the dogbone, while our curved upper arm utilizes our innovative double adjuster design that allows for easy and precise camber adjustment without removing the arm from the vehicle. Our Clamps tightened down with Blue Anodized Titanium Socket Head Cap Screws gives easy access to adjust camber settings, shaving off even more unsprung weight without compromising strength.

Black Anodized 6061-T6 Aluminum Turnbuckles work in conjunction with the left and right hand threaded rod ends for simple and precise adjustment. These endlinks are perfect for street or race applications.

    Please note that if you have changed your OEM shocks with aftermarket shocks or coilovers, the mounting location may have moved. Please check the distance between the swaybar and the shock mount, and confirm that it is between 9.9″ to 11.4″. If it does not fall within this range, please call or email us with the distance required to find you the proper part. SPL cannot confirm fitment with aftermarket shocks and coilovers.
