SPL Parts BMW E9X/E8X/F8X Front Caster Rod Bushings Non-Adjustable

Rubber should be saved for the tires. The factory front caster rod bushings on BMW E9X, E8X and F8X chassis use soft rubber bushings that flex under load, which lets alignment and toe change right when you are asking the car to work the hardest. SPL Parts replaces those links with fully adjustable, spherical bearing components that keep the suspension honest and repeatable on both street and track.

Monoball bushings that do the job

These SPL Parts bushings replace the factory rubber with low friction spherical bearings housed in CNC machined aluminum shells. You get a direct connection between chassis and arm without the slop and spring effect of soft rubber, which improves feedback and keeps alignment where you set it.

Sharper steering from the caster pivots

These SPL caster rod bushings press into the factory arms and replace the soft rubber with low friction spherical bearings. The result is a more direct connection through the steering wheel, better feedback at turn in and less geometry change under braking.

We use SPL hardware across many of our own builds because it is easy to work with, holds settings and stands up to real track mileage. If you are dialing in BMW E9X, E8X and F8X chassis for serious driving, these pieces are a key part of getting the alignment and feedback you want.
