SPL BMW F80 F82 F83 F87 Titanium Rear Upper Arms for M2, M3 and M4
Upgrade your BMW F8X rear suspension with SPL Titanium Series Rear Upper Arms, the ultimate adjustable rear camber arms for F80 M3, F82 M4, F83 M4 Convertible and F87 M2. These motorsport-grade rear upper control arms replace the factory rear wishbone and rear guide links to deliver precise camber adjustment, sharper traction and reduced inner tyre wear on road and track. If your F8X is lowered, these are a must-have to correct the aggressive factory camber curve through bump travel.
At Nforcd we have installed and used these on customer cars and our own builds. The difference in rear-end stability, traction on acceleration and even tyre wear is exactly what fast-road and track drivers want. Customers consistently report easier alignment, repeatable settings and confidence-inspiring grip.
Why choose SPL Rear Upper Arms for your BMW F8X
- Correct rear camber on lowered cars to reduce inner tyre wear and improve traction
- Wide adjustment range for street, fast road and track day alignment setups
- Eliminates soft factory rubber bushing deflection with smooth, quiet FK spherical bearings
- Lightweight construction reduces unsprung weight for sharper handling
- Quick, precise on-car adjustment with SPL’s 360 degree rotating clamp design
Key features
- Gun-drilled 2024 aluminium links, black anodised for durability and corrosion resistance
- Exclusive 6061-T6 aluminium 360 degree rotating clamps for easy, precise camber adjustment
- Blue anodised titanium socket head cap screws reduce weight without compromising strength
- Tapered stainless steel knuckle mount spacers for a secure, OE-quality fit
- Low friction three-piece PTFE Teflon lined FK rod ends and spherical bearings for quiet operation and smooth articulation
Engineering detail
FK spherical bearings and rod ends are manufactured in Connecticut, USA, and utilise a PTFE liner that is self-lubricating and self-cleaning for robust reliability in road and track environments. The liner is chemically bonded to the inner diameter of the race and offers high load capacity with excellent dynamic wear characteristics. Operating temperature range is -65º to 325º F.
SPL’s rotating clamp system removes the hassle of jam nuts and keeps bearing orientation correct while you dial in camber, making alignment faster and more repeatable.
