SPL Parts Adj. Front Caster Rod Monoball Bushings - Toyota Supra A90, BMW Z4 G29

The front caster rods on the Supra and Z4 locate the front wheels with soft rubber bushings that flex under braking and hard cornering. These SPL inserts swap that rubber for spherical bearings, so the arm holds its geometry under load, and they add a caster adjustment the factory parts don't offer.

What you get

• Spherical bearings in place of rubber. 1-inch FK bearings with self-lubricating Teflon liners pivot freely without the deflection of a rubber bushing.
• Adjustable caster. Machined offset spacers allow up to 4 degrees of caster change in either direction.
• 6061-T6 aluminum housings with a knurled outer surface to stay put in the arm.
• A pair, one for each side, made in the USA.

Good to know

• These are bushings only. They press into your factory caster rods, which are not included.
