What vehicles do the SPL Parts Rear Upper Arms for F8X fit?

The SPL Parts Rear Upper Arms for F8X (RUA F8X) fit the F80 M3 (2015-2018), F82 and F83 M4 (2015-2020), and F87 M2 (2016-2021). Confirm your chassis before ordering these SPL F8X rear upper arms.

What is included in the kit?

The SPL F8X rear upper arms are sold as a complete kit for one car, 4 total arms, replacing both the rear wishbone and rear guide links on both sides of the car. One kit covers the full rear upper setup.

Why do I need adjustable rear upper arms on an F8X?

The stock F8X has an aggressive rear camber curve through bump travel that is pronounced on lowered cars, causing inside-edge tire wear and traction loss. The SPL F8X rear upper arms give a wide camber adjustment range to dial the rear back into spec for street or track.

What do these arms improve over stock?

The SPL F8X rear upper arms replace the soft factory rubber bushings with Teflon-lined FK rod ends, eliminating bushing deflection under load. That gives more consistent rear camber geometry and sharper, more predictable handling than the flexy stock links.

How are they adjusted?

The SPL F8X rear upper arms use the exclusive SPL 360-degree 6061-T6 aluminum Rotating Clamp design with titanium socket-head cap screws, so rear camber is set and locked quickly and precisely without fighting jam nuts.

Will these add noise?

Some. The FK rod ends transmit more feedback than the stock rubber bushings, though the self-lubricating Teflon liner keeps operation quiet and smooth. A slight increase in noise and vibration is normal for a performance rear arm on a street-driven M car.

Description

SPL Parts Adjustable Rear Upper Arms for F8X BMW M2 / M3 / M4

SPL Parts’ Adjustable Rear Upper Arms for F8X BMW M2, M3 and M4 maintain proper rear camber and reduce tire wear on the street and track. The stock setup has an aggressive camber curve through bump travel that is very apparent on lowered cars, where excess negative camber wears the inside tire edge and cuts acceleration traction, while too little camber limits rear grip in corners. These arms provide a wide adjustment range for precise rear camber that is easily optimized for street or track, and Teflon-lined FK rod ends replace the soft factory rubber bushings to eliminate deflection under load. The kit replaces the factory links commonly called the rear wishbone and rear guide links.

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.
