Take full control of your alignment with SPL Parts Front Lower Control Arms for the A90 Supra and Z4. These adjustable front lower control arms give you roll center, camber, and track width adjustment in one piece, correcting the geometry issues that come with a lowered car and unlocking real front grip on the street or track.
At the heart of the arm is SPL's exclusive Double Adjuster, machined from 4130 chromoly, gun drilled to save weight, and electroless nickel plated for corrosion resistance. The rotating clamp design lets you lock down camber and track width without fighting jam nuts or losing your bearing orientation. Low friction Teflon lined FK spherical bearings and rod ends replace the soft OEM rubber bushings, eliminating the flex and binding of the factory control arms while keeping the correct ball joint angle for full articulation.
Built from lightweight 6061-T6 billet aluminum with titanium hardware to cut unsprung weight, these arms include stainless steel roll center spacers to correct geometry on a lowered car. Made in the USA and sold as a pair.
Before purchasing, note that from the factory the sway bar sits very close to the lower control arm on these cars, and this arm does not change that. If you run an aftermarket sway bar or added caster, check clearance to the control arm before driving, as contact can damage the arm and load the bearing. SPL's Caster Rod Bushings (CRB G29) or Adjustable Front Endlinks (FE G29) can create the needed space if you have a clearance issue.
