SPL Parts Adjustable Front Lower Control Arms for G29 BMW Z4 and A90 / A91 Toyota Supra GR

SPL Parts Adjustable Front Lower Control Arms for G29 BMW Z4 and A90 / A91 Toyota Supra GR

SPL Parts’ Front Lower Control Arms (FLCA) offer roll center, camber, and track width adjustment for the 2020+ Toyota Supra, providing full articulation with the correct ball joint angle. The main arm is slotted to accommodate pinch bolts, while SPL Parts’ exclusive Double Adjuster features rotating clamps that securely lock camber and track width settings in place. This design eliminates the need for jam nuts, simplifying the process by removing the hassle of managing multiple wrenches while keeping bearings properly aligned.

The Double Adjuster, machined from 4130 Chromoly, is gun drilled to reduce weight and electroless nickel-plated for corrosion resistance. Blue anodized titanium hardware reduces unsprung weight without compromising strength. Stainless steel spacers are included to correct roll center for lowered vehicles. The use of FK Rod Ends and High Misalignment Spherical Bearings ensures smooth articulation, eliminating the flex and binding present in OEM control arms.

Notes

• Instruction manual
• On the 2020 Supra and 2019 Z4, the swaybar is positioned very close to the lower control arm from the factory, and SPL Parts’ lower control arm does not alter this proximity. If aftermarket swaybars or caster adjustments are installed, it is important to check the clearance to the lower control arm before driving. Any contact between SPL Parts’ Front Lower Control Arm and the swaybar could damage the arm and apply excessive force on the bearing. If a clearance issue arises, SPL Parts offers solutions including their Caster Adjustable Tension Rod Bushing and Adjustable Front Endlinks, which can create the necessary space for both arms to move freely.
