For those that don't know, all BMW E46's suffer from the Subframe crack issue, this is a kit you can install to help reinforce the weak areas and prevent it from happening. Looks like fun.
One of the most wildest cars I've had a ride in, is a BMW E46 M3 supercharged....so I have a major soft spot for these cars.
