Dettagli prodotto
These offset rear monoballs for the rollover strut on F8X, G8X, & E9X M2/M3/M4 correct suspension geometry and roll center on cars that have been lowered a lot. When lowering ride height the suspension arms end up at a different angle than original, which will affect their orientation, travel, and operation - specifically affecting the roll center of the car. Our bearings replace the inner bushing on the subframe.
This is a spherical monoball bearing with an offset housing and slightly different in design and purpose than our standard inner bearing upgrade (link). The offset housing corrects for lowered ride height and installs with the mounting hole in the highest position. This restores the geometry of the rear suspension closer to original. Unlike others we chose to replace the inner bushing instead of the outer because it gave us an opportunity for a larger bearing capable of higher loads and the outer bushing is a sealed bearing already. The stock outer bearing is already a monoball design and there is not much improvement over the stock part.
The spherical bearing inside is a full solid bearing capable of sustaining high loads and with zero deflection. It's similar to the inner bearing found on the GT4 race cars but with a higher load rating. Because of the solid, non-sealed design, this is only recommended for track and race cars. For street use, we recommend our non-offset Sealed Bearing Kit (see Related Items below).
This monoball rear bushing replaces the OEM rubber installed on the subframe for the rear rollover struts (aka camber arm or spring arm). The offset housing is zinc-plated steel and we recommend a tack weld to hold it in place on the rear subframe. Install the housing so the bearing sits at the highest position (and aligned plumb). The bearing is replaceable without having to remove the housing.
Sold as a complete kit and fits E9X non-M, F87 / G87 M2, F80 / G80 M3, and F82 / G82 M4. It may fit other models with the similar rear suspension (E9X 335i, E82 135i, E82 1M). Other spherical rear suspension pieces are recommended (see Related Items below).

Bought the Infinity Design S65 Modular Carbon Plenum for my E9X M3. The finish is excellent and it completely transforms the look of the engine bay. It feels like a properly engineered piece rather than just a cosmetic upgrade. Really pleased with how it looks once fitted.

I went with the Endless MX-72 Plus Brake Pads for my G8X and they've been a great upgrade. The pedal feels positive and the pads give plenty of confidence when braking hard. They also work well for normal road driving, which was important to me. CPC Clubsport made the whole ordering process easy.

Had the Nitron NTR R3 Coilovers fitted to my E9X M3 and the difference is impressive. The car feels much more controlled and planted, particularly through faster corners. The adjustability is a big advantage as well, allowing the setup to be tailored to how I use the car. Excellent upgrade for a car that sees both road and track use.

Fitted the Ferodo DS1.11 Brake Pads F8X (Front) to my F82 M4 and they've been excellent. The initial bite is strong and the braking feels much more consistent when pushing the car hard. They’re particularly impressive on track where the brakes stay predictable through repeated heavy braking zones. Very happy with the purchase and service from CPC Clubsport.
