SPL Parts Tie Rod Ends Bumpsteer Adjustable for BMW E9X/E8X

Fitment depends on the exact chassis, model, model year, drivetrain and suspension package. Check the vehicle application and SPL manufacturer SKU shown above. M and non-M BMW models may use different parts, and Porsche GT versions often have different suspension arrangements. Contact us with your vehicle details if anything is unclear.

No. Some SPL kits are specific to M vehicles or rear-wheel-drive models, while others have dedicated xDrive versions. Do not use a part purely because the chassis family looks similar. Verify the complete SPL part number against your exact model and drivetrain before ordering.

No. SPL specifically excludes Cayman GT4 fitment for the SPL-RLCA-981 and SPL-RLCA-982 rear lower control arm kits. Other GT4, GT4 RS and Spyder applications must be assessed separately using the correct manufacturer part number. We can help identify a suitable alternative.

Adjustable toe links increase the usable rear toe adjustment range. An eccentric lockout replaces a compatible factory eccentric adjustment location so the setting is controlled by the adjustable link. They are often used together when lowering a car or pursuing more precise track geometry. Only install a lockout with the intended compatible components.

Adjustable suspension arms can help achieve camber, toe or roll-centre targets that the factory hardware cannot provide, particularly after lowering. The benefit depends on the vehicle, tyres, setup and chosen alignment. Increased adjustability does not automatically mean that more negative camber or a more aggressive setting is better.

These components can reduce unwanted compliance at the front axle and, on adjustable versions, provide extra scope to tune caster. This can influence steering response, stability under braking and steering self-centring. Confirm the exact application, bearing design and any xDrive exclusions before selecting a kit.

Only if a measured geometry issue justifies them. Bump steer is toe change during bump and rebound. Lowering can change steering-link angles, but the correct adjustment requires measurement through suspension travel. Use the part that matches your steering arrangement and have it set up by a competent alignment specialist.

Some may be suitable for road-focused builds, but spherical joints can transmit more noise, vibration and harshness than factory rubber bushes and may require more inspection and maintenance. Consider comfort, durability and local road-use requirements as well as performance when choosing between an original-style bush and a motorsport-oriented joint.

Contents vary by manufacturer SKU. Certain links are sold as pairs or complete axle kits; others are individual components or lockout hardware. Use the What is included information in the product description and confirm any required spacers, bolts or joint hardware before booking fitting. Product photographs alone should not be used to determine kit contents.

Yes. Adjustable arms, toe links, caster components and bush conversions can change wheel geometry. Professional installation, joint-angle and clearance checks, correct torque settings and a four-wheel alignment are essential. Track cars may also benefit from corner weighting and a setup check after initial use.
