For those who want to use a polyurethane bushin, Harrison Motorsports and AKG offers a 75D hardness. 75D is by far the hardest polyurethane compound available on the market for a BMW and will tremendously improve many aspects of a race car's handling characteristics. AKG's 75D polyurethane bushings utilize the correct compound polyurethane required to control a racecar's suspension geometry during the rapid movements a race car experiences on the track. For those who want to go a step further, we also offer aluminum bushings for most models.
