How many degrees can the BMW rear wheel camber be adjusted?

The camber angle is generally suitable between 1-2 degrees. BMW rear wheel camber adjustment method: Measure the rear wheel values, and adjust the required angle by changing the length of the inner and outer threaded adjustment sleeves through screwing in or out. Effects of incorrect wheel camber angle on the vehicle: It will accelerate the wear of suspension system components; excessive positive camber angle will cause unilateral wear on the outer side of the tire, and the car will pull towards the side with a larger positive camber angle; excessive negative camber angle will cause unilateral wear on the inner side, and the car will pull towards the side with a smaller negative camber angle; correct angle adjustment can make the wheels roll close to vertical to the road surface, reducing sliding and steering resistance, and improving the ease of front wheel steering operation.
As a veteran BMW driver with over a decade of experience, I can share some insights. The rear wheel camber angle can indeed be adjusted, but the specific degree depends on the model. When I had my 5 Series aligned last time, the technician said adjusting about 1 degree would make it quite stable without causing significant changes. Generally, the factory setting might be around -1 degree, and with proper tools, it can be adjusted to -1.5 or -2 degrees, but don't exceed -2.5 degrees, otherwise the inner tire wear will accelerate, compromising safety. Newer models like the G series might be easier to adjust, typically within a range of ±1 degree, while older cars like the E90 can be adjusted to ±1.5 degrees. I recommend going to a professional shop with laser alignment equipment rather than attempting it yourself to avoid damaging the suspension. After adjustment, it's best to check the tires regularly and get an alignment every six months to maintain proper angles. Don't sacrifice safety for cornering performance by over-adjusting; balance is key. This minor tweak can improve handling and reduce high-speed instability.
Last month I adjusted the rear wheel camber angle on my BMW 3 Series, and it's definitely worth sharing. The adjustable range is between -1 to 2 degrees, with specific adjustments depending on the situation: for example, my car came from the factory at -1 degree, and I adjusted it to -1.2 degrees, making it more stable during turns. The technician explained that the typical adjustable range is usually ±0.5 to 1 degree, and if the suspension has been modified, it can go up to ±1.5 degrees. However, adjusting too much comes with risks, such as faster tire wear—I've seen a friend's tires wear out in less than six months after adjusting to 2 degrees. So now I always stick to regular alignment checks, keeping the angle within the safe range. For daily driving, minor adjustments don't affect fuel consumption and can even save a bit on gas. In short, don’t blindly chase angle changes—finding a reliable repair shop for the job is the safest approach.
