SPL Parts – Toyota GR Supra (A90)

Front suspension: front lower control arms, adjustable and non-adjustable front caster rod bushings, front swaybar endlinks, and bumpsteer adjustable tie rod ends. Rear suspension: rear toe links, rear upper lateral links, rear traction links and rear swaybar endlinks. Alignment hardware: camber, toe and rear toe arm eccentric lockout kits that hold a set alignment once dialled in. Driveline: solid differential mount bushings to limit subframe and diff movement.

The key fitment identifier is the A90 chassis code (also referred to as the A90/A91 GR Supra). Most listings also note BMW Z4 (G29) compatibility because the suspension hardware is shared. Check the product title and description for the exact chassis code, and confirm whether the part is front or rear and adjustable or non-adjustable before ordering. If your car already runs aftermarket arms, coilovers or a modified ride height, compare the existing component against the listed part to avoid duplication.

Fitting these components generally requires the vehicle to be safely raised and supported, removal of the road wheels, and access to metric spanners and sockets, a torque wrench and often a press for bushing work. Installation by a professional workshop is recommended. A wheel alignment should be carried out after fitting any arm, link, tie rod end, lockout kit or bushing, as alignment settings will change.

Q: Do SPL Parts GR Supra components also suit the BMW Z4 (G29)?
A: Many are listed for both chassis. Check each product title for the G29 reference.

Q: What does an eccentric lockout kit do?
A: It replaces the factory eccentric adjusters so the chosen camber or toe setting is held in place.

Q: Will I need an alignment afterwards?
A: Yes — a wheel alignment is recommended after fitting any suspension arm, link or bushing.
