E82/E87 1 Series Hardrace Rear Camber Arms

Hardrace adjustable rear camber arms give you greater control over the rear geometry of the BMW E82 and E87 1 Series, with a choice of uprated rubber bushes or rose jointed ends depending on how track-focused you want the car to be.

The factory camber adjustment can become restrictive once the car is lowered or you start moving towards a more aggressive track alignment. These arms provide a wider range of adjustment, allowing you to set the rear camber around your tyre, suspension and intended use rather than being limited by the standard setup. This item comes as a pair.

What it’s good for

A great upgrade for E82 and E87 1 Series being built for fast road and track use. The additional adjustment allows you to properly dial in rear camber, helping you manage the balance between lateral grip, traction and tyre wear.

For more dedicated track cars, the rose jointed version also reduces compliance in the rear suspension under load. This helps the rear geometry remain more consistent through high-load corners, particularly when running coilovers, stiffer spring rates and high-grip track tyres.

Rubber or rose jointed?

Uprated rubber (7594)is the better choice for cars that still see plenty of road mileage while being used regularly on track. You get the additional camber adjustment while retaining some compliance in the suspension, keeping NVH closer to the factory setup.

Rose jointed (6831) is our choice for a more track-focused car. Removing the compliant rubber joint gives more precise control of the rear suspension and reduces geometry changes under load. The trade-off is increased NVH and a greater requirement for regular inspection and maintenance.

What we like about it

Having both options means you can choose the arm around how the car is actually being used. You don't necessarily need rose joints to benefit from adjustable camber, particularly on a dual-purpose road and track car.

Once outright track performance becomes the priority, however, the rose jointed version makes more sense. Combined with a proper alignment, it gives you much greater control over the rear axle and allows you to build the geometry around the way you want the car to behave on circuit.
