The factory OEM front lower control arm rubber bushings allow alignment geometry to shift under braking and cornering loads, contributing to vague front-end response. The \u003cstrong\u003eSPL FLCA G29\u003c\/strong\u003e replaces these bushings with FK Rod Ends and High Misalignment Spherical Bearings to eliminate bushing flex and binding. The slotted arm body accommodates the exclusive 4130 Chromoly Double Adjuster with 360-degree rotating clamps for camber and track width adjustment without jam nuts. Stainless steel roll center spacers are included for lowered applications. SPL Parts notes that on the 2020 GR Supra and 2019 BMW Z4, the sway bar runs close to the lower arm as a factory characteristic; use the SPL CRB G29 caster monoball bushings and SPL FE G29 endlinks if sway bar clearance is a concern.

This is a factory design characteristic that applies to the OEM arm and the \u003cstrong\u003eSPL FLCA G29\u003c\/strong\u003e equally.

Teflon-lined FK Rod Ends operate silently, are self-lubricating, and are rated from -65 to 325 degrees F.

Add spacers above the bearing only when the vehicle has been lowered to correct the resulting roll center drop.

A professional four-wheel alignment is required after installation to set final camber, toe, and verify caster.
