SPL Parts 06-13 BMW 3 Series/1 Series (E9X/E8X) Rear Toe Links w/Eccentric Lockouts (Excl M Models)

Rear Toe Links with Eccentric Lockout for BMW 3 Series and 1 Series (E9X/E8X Non-M)

The SPL RTAEL E9X brings track-proven rear toe link technology to non-M BMW 3 Series (E90/E91/E92/E93) and 1 Series (E81/E82/E87/E88) owners. The SPL RTAEL E9X replaces the OEM rubber-bushed toe link with a billet 2024 aluminum assembly featuring low-friction PTFE-lined FK Heim joints and a 6061-T6 aluminum eccentric lockout washer system. The eccentric lockout keeps your chosen toe setting fixed under all driving conditions, eliminating the gradual toe drift that OEM rubber bushings allow. Available at a price well below MSRP, these rear toe links are ideal for enthusiasts who want precise, adjustable rear toe on E-chassis BMWs without M-model pricing.

Frequently Asked Questions

What is the SPL RTAEL E9X and what does it do?
These are billet aluminum rear toe links for non-M BMW E9X 3 Series and E8X 1 Series models. They replace the OEM rubber-bushed toe links to provide adjustable, deflection-free rear toe positioning.

What adjustment range does the SPL RTAEL E9X provide?
These toe links provide approximately +/-6mm of adjustment from the OEM toe position, giving alignment technicians a meaningful range to dial in rear toe for street alignment, autocross, or track use.

How does the eccentric lockout work?
After alignment is set, the 6061-T6 aluminum eccentric lockout washer is rotated to engage and clamped against the subframe bracket. This prevents the toe link from rotating under braking and cornering loads, keeping alignment consistent over time.

Does the SPL RTAEL E9X fit the BMW M3 or 1M Coupe?
No. The M3 and 1 Series M Coupe use different subframe mounting geometry. Those vehicles require the SPL RTAEL E9M, which is designed specifically for M-chassis E9X and E8X models.

Are these toe links safe for street driving?
Yes. The PTFE-lined FK rod ends provide smooth articulation that does not introduce harsh NVH at normal road speeds. The eccentric lockout keeps alignment stable, which many drivers find improves straight-line tracking compared to worn OEM rubber bushings.

Will installing the SPL RTAEL E9X void my factory warranty?
Under the Magnuson-Moss Warranty Act, an automobile dealer or manufacturer cannot void a factory warranty simply because an aftermarket part was installed. The manufacturer must show that the aftermarket part directly caused the failure in question.

What is the torque spec for the subframe bolt?
Torque the subframe end bolt to 73.7 ft-lbs (100 Nm). Use OEM torque specifications at the knuckle mounting point. Always re-torque after the first heat cycle and verify alignment after any torque check.

How long do the PTFE rod ends last?
With normal street and track use, PTFE-lined FK rod ends are very durable. Inspect for play or roughness during annual brake service or any time the rear suspension is accessed. Replacement rod ends are available separately from SPL Parts.

Installation Instructions

1. Safely lift and support the vehicle on rated jack stands. Remove the rear wheels.
2. Locate the OEM rear toe links at the subframe and rear knuckle mounting points.
3. Support the rear knuckle and trailing arm with a floor jack before removing the toe link to prevent sudden drop.
4. Remove the OEM toe link bolts at both ends. Note OEM bolt orientation for reference.
5. Thread the SPL RTAEL E9X rod ends to match the OEM link length to establish a baseline toe setting.
6. Install the toe links using the supplied grade 10.9 hardware at the subframe end and OEM hardware at the knuckle end.
7. Install eccentric lockout washers at the subframe end, leaving them loose until alignment is complete.
8. Snug all fasteners and reinstall the wheels. Lower the vehicle to ride height.
9. Have a professional four-wheel alignment performed. Adjust toe by rotating the link tube.
10. After desired toe is set, torque the subframe bolt to 73.7 ft-lbs (100 Nm) and secure the eccentric lockout washer.
11. Re-torque all fasteners after the first drive cycle. Verify alignment has not shifted.
