SLG E8X/E9X Rear Suspension Bundle

Take Control of Your Vehicle’s Performance with Race-Engineered Rear Suspension Arms

Upgrade your vehicle’s handling with our complete set of race-proven rear suspension arms, featuring Toe, Camber, and both Guide Arms. After extensive development and rigorous testing at GridLife racing events, these suspension arms have been pushed to their limits—proving their durability even in the harshest racing conditions, including high-impact collisions and airborne moments.

Fed up with suspension arms that wear out or seize? We were too. That’s why we developed the most reliable link system on the market, crafted from true motorsport-grade materials. This is an investment built to last, and with spare parts and boot kits readily available, your suspension will be ready for anything the road throws at it.

Why Choose Solid Arms?

In certain positions, factory-installed arms offer no adjustability. In these cases—like the Guide arms— we make them solid, reducing complexity and the risk of misalignment. The result? A lighter, stronger, and more cost-effective solution that enhances performance while keeping your suspension geometry intact.

Premium Construction for Maximum Performance

Crafted from billet 6061 aluminum, these arms are engineered for strength without the weight penalty. Featuring huge Heavy-Duty FK Bearings—made in the USA—these components last 3 to 4 times longer than standard bearings. Zinc-coated 4140 steel barrel adjusters further enhance durability and performance.

For added convenience, the camber arm adjusters feature an internal hex design, allowing you to make quick adjustments with an Allen wrench, even while your car is on the alignment rack. This feature is perfect for on-the-fly tweaks during track days.

Enhanced Handling and Cornering Stability

By eliminating rubber joints and bushings, our suspension arms dramatically reduce deflection, providing sharper, more consistent handling. This is especially beneficial when running wider, high-grip tires. By replacing almost all of the rubber bushings in the rear suspension, this kit delivers a firmer, more direct connection—improving cornering stability and suspension response.

Complete Kit with Eccentric Lockouts

The kit includes all the high-quality hardware you need, along with eccentric camber lockout plates for a secure installation. When using stock arms, toe and camber adjustments rely on eccentric bolts, which can slip under high loads, causing unwanted changes in alignment. With our adjustable links, you can eliminate this eccentric system by using our provided hardware and zinc-coated lockout plates to secure the suspension geometry. 

Wide Range of Adjustability for Any Driving Style

Whether you're drifting, drag racing, or tearing through canyon roads, our adjustable camber and toe arms offer a wide range of alignment options to match your driving style. Enjoy greater control and precision, no matter the conditions.

Less Maintenance, More Driving

Our suspension arms feature Heavy-Duty FK Bearings with a Teflon liner, providing a service life that’s 3-4 times longer than standard spherical bearings. Built for high misalignment and smooth, bind-free operation, these bearings are crafted from heat-treated 52100 steel and chrome-plated for extra durability. Paired with the PTFE-lined alloy steel race to reduce friction and block dust, these bearings are also easy to replace when needed, ensuring minimal downtime and more time on the track.
