Just put the motor back in the other day and my clearances were pretty good all around using the stock S52 M3 Header and Down Pipe. However the down pipe was about 2mm from the frame and just touching the sway bar and about the same to the e36 rack (shimmed half under and half over). My question is I tried shimming the motor this morning, my spacer is 8.25mm it seemed to help a lot all around, but will it create other problems. I like the extra ground clearance. Also I shimmed under the arms would under the mounts be better. The car is a 91 318is, S52, e28 535 mounts.
Thanks
