SPL Adjustable Front Lower Control Arms / Wishbones for Toyota GR Supra Mk5 A90 A91 & BMW Z4 G29 - Front Camber Arms, Roll Centre + Track Width Adjustment - Billet Aluminium, Titanium Hardware - Pair - SPL FLCA G29

SPL Front Wishbones for A90 Supra and G29 Z4 with Titanium Fasteners and Billet Alloy Arms

Transform the front end of your A90 GR Supra or BMW Z4 G29 with these motorsport-grade SPL front wishbones. Engineered to let you fine tune front geometry for serious grip, these lightweight alloy suspension arms deliver precise negative camber adjustment, roll centre correction and track width tuning while cutting unsprung mass. Ideal for fast road, track day, time attack and drift builds that demand sharper turn in, improved steering feel and consistent alignment under load.

We run these arms on our own cars and customer builds at MJ Modifications and the results are superb. Setup is quick on the car, the settings stay put and the front end response is night and day better.

Key advantages

• Dial in front end geometry for grip and tyre wear, from subtle street setups to aggressive track alignment

• Made in the USA, supplied as a matched left and right pair

Construction highlights

• Slotted main arm accepts pinch bolts for secure clamping and easy serviceability

Clearance note

On A90 Supra and G29 Z4 platforms the factory anti roll bar routes close to the lower arm. These arms maintain that relationship. If you run an aftermarket anti roll bar or any caster adjustment, check clearance to the arm before driving. Contact between the arm and the bar can damage the arm and overload the bearing. If space is tight, companion parts such as the Castor Adjustable Tension Rod Bushing (CRB G29) and Adjustable Front Endlinks (FE G29) can provide the required clearance. Contact us if unsure.

Installation and setup

Professional fitting and four wheel alignment are recommended. MJ Modifications in Warwickshire can supply, install and align. For a fitting quote email info@mjmodifications.co.uk.
