Front Lower Control Arms

The SPL Parts Front Lower Control Arms (FLCA) offer significant adjustability for the 2020+ Toyota Supra (A90 GR) and 2019+ BMW Z4 (G29). The main arm is slotted to accommodate pinch bolts, and SPL's exclusive Double Adjuster, featuring rotating clamps, eliminates the need for traditional jam nuts, simplifying alignment adjustments. Constructed from lightweight 6061-T6 billet aluminum with blue anodized titanium hardware, these control arms minimize unsprung weight without sacrificing strength. The Double Adjuster itself is machined from 4130 Chromoly, gun-drilled for weight reduction, and electroless nickel plated for corrosion resistance. Stainless steel spacers are included to correct the roll center for lowered vehicles. The use of FK Rod Ends and high-misalignment spherical bearings replaces the flex and binding found in OEM control arms, ensuring smooth operation and enhanced performance. Before purchasing, it is crucial to note that the swaybar on the 2020 Supra and 2019 Z4 comes very close to the lower control arm from the factory, and these aftermarket arms do not alter this clearance. If you have aftermarket swaybars or caster adjustment components, ensure there is adequate clearance to the new lower control arm before driving. Contact between the control arm and swaybar can lead to damage. SPL Parts offers solutions like their Caster Adjustable Tension Rod Bushing (CRB G29) and Adjustable Front Endlinks (FE G29) to create necessary space if clearance issues arise.
