What vehicles do the SPL Parts Camber Arms for G8X fit?

The SPL Parts Camber Arms for G8X (RUA G8X) fit the G87 BMW M2 (2023-present), G80 and G81 M3 (2021-present), and G82 and G83 M4 (2021-present). Confirm your chassis before ordering these SPL G8X rear upper arms.

What is the key difference between the SPL G8X rear upper arms and the F8X version?

Both kits include the rear wishbone (camber arm) and rear guide link (traction arm) for four arms per car. The difference is the camber arm design. The SPL G8X rear upper arms use a curved 6061-T6 billet upper arm with a double adjuster that allows camber adjustment without removing the arm; the F8X version uses a straight arm that requires removal. The two are generation-specific and not interchangeable.

How does in-car camber adjustment work?

The curved profile of the G8X upper camber arm provides the clearance to reach the double adjuster while the arm is installed. The adjuster is turned to dial in the camber value, then the 360-degree rotating clamp locks it with a single allen key, no jam nuts. The arm stays on the car throughout.

Why do I need adjustable rear upper arms on a G8X?

The stock G8X has an aggressive rear camber curve through bump travel that is pronounced on lowered cars, causing uneven inner-edge tire wear and a shifting rear grip balance. The SPL G8X rear upper arms give the wide camber range needed to dial the rear back into spec for street or track.

The SPL G8X rear upper arms are sold as a complete four-arm kit, covering the rear wishbone and rear guide link at both rear corners, so one kit does the full rear upper setup on the car.

Description

SPL Parts Adjustable Rear Upper Camber Arms for G8X BMW M2 / M3 / M4

SPL Parts’ Adjustable Rear Upper Camber Arms for G8X BMW M2, M3 and M4 are a complete four-arm rear upper kit that addresses the aggressive rear camber curve these cars carry through bump travel, a geometry trait that becomes a practical problem as soon as the car is lowered. The camber goes negative faster than the factory eccentric adjustment can compensate for, tire inner edges wear unevenly, and rear grip balance shifts in ways springs, dampers, and factory alignment range cannot resolve. This kit provides a wide adjustment range that covers any camber target at any ride height, and what sets it apart from the F8X version is the curved 6061-T6 billet aluminum upper camber arm with SPL’s double adjuster, which lets camber be set without removing the arm from the car, a trackside task rather than a workshop job.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
