SPL Parts EL G29 Rear Toe & Camber Lock Plates – Eccentric Bolt Delete/Lockout Alignment Kit for Toyota GR Supra A90 Mk5/MkV (2020+) & BMW Z4 G29 (2019+) | Rear Suspension Geometry Alignment Fix Track/Drift

Rear geometry lock plates for Mk5 Supra A90 and BMW Z4 G29

Stop your alignment wandering and lock in your set-up with the SPL EL G29 toe and camber lock plates. This motorsport-grade hardware replaces the factory sliding adjusters at the rear of the car, eliminating movement under load so your suspension settings stay exactly where your alignment technician put them. Perfect for track days, drifting, time attack and fast-road driving on sticky tyres and coilovers.

We have installed this kit at MJ Modifications and it delivers. Sharper turn-in, a calmer rear end and more even tyre wear. Customers love the confidence it gives when pushing hard lap after lap.

Key advantages

• Eliminates rear-end geometry shift under braking and cornering
• Locks toe and camber for repeatable alignment and predictable handling
• CNC machined 6061-T6 aluminium plates with precise indexing
• High tensile zinc-plated 10.9 bolts, washers and lock nuts for secure clamping
• Ideal with semi-slicks, wide wheels and coilover suspension
• Made in the USA, engineered for performance and durability
• Complete kit for one vehicle

What it does

The OEM eccentric bolts can rotate when subjected to high cornering loads, causing toe and camber to shift. These lock plates replace those eccentrics, turning the rear adjustment points into fixed locations so your alignment does not creep between sessions or road miles. The result is stable geometry, consistent grip and improved confidence.

Compatibility

• Toyota GR Supra A90 2020 onwards
• BMW Z4 G29 2019 onwards

In the box

• Rear toe and rear camber lock plates
• Zinc-plated grade 10.9 fixings, washers and lock nuts

Important fitment note

Once the factory eccentrics are deleted you will need adjustable rear arms to fine-tune toe and camber. A professional four-wheel alignment is strongly recommended after installation.
