The N15 Design E46 rear subframe bushings were designed to improve rigidity in the rear subframe assembly. The stock bushings allow the rear subframe to shift and twist to the detriment of handling and structural integrity of the rear axle carrier panel.
These bushings feature a hybrid delrin/aluminum construction and are SCCA T2, Grand-Am, and BMWCCA legal. Precision CNC machined from 6061 aluminum. Stiff enough for a race car and add minimal NVH for street cars. You’ll wonder why these cars didn’t come with these from the factory.
While these bushings significantly reduce the flex that creates the conditions leading to RACP failure, we still recommend reinforcing the chassis subframe mounting points.
Compatible with all E46 models.
Full installation instructions are included with each set.
