The rear sway bar mounting points on your e30 are very thin and could break under heavily driven cars, this is common for cars with larger upgraded sway bars (and even factory bar cars driven hard) that adds additional stress on weak rear sway bar mounting points.
If you track, autocross or upgrade your e30 with a bigger sway bar, than we recommend you strengthen your mounting points with our reinforcement kit.
This Reinforcement Kit includes:
Rear Sway Bar Reinforcement
If you want to strengthen your entire chassis and save some money at the same time, order our Complete subframe Reinforcement Kit here!
