hey guys i have some H&R hubcentric spacers for my s13 and when i put it on, it seems loose in the rear. whenever i go over cracks or undulations in the road, the rear seems to follow it. im guessing it has to do with the spacer because it doesnt happen without them.
heres the spacers in question

i took it off the spacers to test it and it does seem to lessen the frequency of the loose rear end.
do any of you guys have this problem with slipons? i dont feel safe driving like this on the freeway.
