thanks for the feedback
i guess the issue isnt that it bounces some, thats understandable on a street suspension.
the issue is the unsettled feeling and harsh movements up and down when the car is lowered. like a rapid slamming feeling, basically throwing you almost out of your seat.
in the end, ive decided to go with the bmw performance suspension setup in full and almost certainly adding the m3 front control arm retrofit kit
id rather not run the subframe bushings at this time due to the massive labor involved.
