As E46s get older and see more track-use, they start develop cracks and bends in places that see a lot of stress. One of the most stressful areas is the front subframe. It's a good idea to reinforce your front subframe the next time you're doing any suspension work. This kit reinforces the upper and lower tabs of the subframe where the motor mount is located. Requires welding.
