Everyone told me it was a pain and it will vibrate my fillings out of my teeth. Such BS. Spoken by people that never had one. Rubber mounts shake the car WAY more. Same people that said I couldn't run a tunnel ram, much less 660s, and a spool on the street. The SG is easier in turns in a parking lot, but overall, the spool is super easy, easier than the Dr Diff locker on the street
