Fitment Notes

• This kit locks out the rear TOE arm eccentric only - it does not replace the camber arm eccentric. For full eccentric lockout (toe + camber), see SPL ELC F8X.
• Adjustable rear toe control arms (such as SPL RTA F8X) are required to set toe after the stock eccentric bolt is eliminated.
• Compatible with both RWD and xDrive AWD variants on G8X (G80/G82/G83/G87) platforms.
• All F8X chassis (F80/F82/F83/F87) are RWD only - no AWD variants exist for these platforms.

Features

• Eliminates factory eccentric toe bolts that are known to slip under high cornering loads, causing unwanted rear alignment shifts during aggressive driving.
• CNC machined from 6061-T6 aluminum for a lightweight, precision-fit concentric lockout plate that replaces the OEM eccentric bolt and washer assembly.
• Supplied with CAD (zinc) plated grade 10.9 hex cap bolts and nylon lock nuts, providing a zero-slip, fastened connection with superior clamp load versus stock hardware.
• Designed specifically for the F8X and G8X toe arm mounting locations - no modification or drilling required for installation.
• Permanently fixes rear toe at your dialed-in alignment setting, ideal for track use, time attack, autocross, and spirited street driving.
• Significantly reduces the risk of alignment drift between track sessions, eliminating the need to re-check and re-align after every event.
• Engineered, manufactured, and quality-checked entirely in the USA by SPL Parts in-house team of machinists and engineers.
• Sold as a complete kit for one vehicle - includes washers and hardware for both rear toe arms simultaneously.
• Works in conjunction with SPL rear toe arms (RTA F8X) and is included as standard in the SPL Rear Toe Links + Eccentric Lockout bundle (SPL RTA F8X + ELT).

Product Description

The SPL Parts SPL ELT F8X Rear Toe Eccentric Lockout Kit is a purpose-built alignment retention solution for BMW F8X and G8X M-series vehicles. The OEM factory toe arm eccentric bolt, while useful for minor toe adjustments from the factory, is notorious for slipping under the intense lateral loads generated during performance driving. When this happens, rear toe shifts mid-corner, resulting in unpredictable handling, accelerated tire wear, and the need for frequent re-alignment. The SPL ELT F8X kit eliminates this failure point by replacing the eccentric bolt and washer with a precision CNC machined 6061-T6 aluminum concentric lockout plate, paired with CAD plated grade 10.9 hardware and lock nuts that hold absolutely firm under race-level cornering forces.

Installation is straightforward and does not require permanent vehicle modification. The lockout plates are engineered to drop directly into the factory toe arm mounting location on all F8X chassis (F80 M3, F82/F83 M4, F87 M2) and G8X chassis (G80 M3, G82/G83 M4, G87 M2). Because the factory eccentric bolt is the only means of toe adjustment on these platforms, it is essential to pair this kit with adjustable rear toe arms such as the SPL RTA F8X - the lockout removes the OEM adjustment mechanism entirely, so a dedicated adjustable arm is required to set and fine-tune rear toe prior to locking it down.

The SPL ELT F8X is the ideal upgrade for any F8X or G8X M car that sees track use, autocross, aggressive street driving, or any application where a consistent, locked-in rear alignment is critical. Once installed and aligned to your preferred toe setting, the lockout ensures that setting stays exactly where you put it - session after session, lap after lap. Designed and manufactured in-house in the USA by SPL Parts, this kit reflects the same high-tolerance machining and material standards found across SPL's full suspension lineup. Sold as a complete kit for one vehicle, covering both rear toe arm positions.
