In order for my new rims to clear my calipers I had to put 1/4" spacers on the back wheels. I also put 7/16" spacers on the front but 1/4" would do the trick. The shop didn't have 1/4" at the time. Am I going to run into any problems with this? They're the cheap kind of spacers not the H&R style. I would get the nicer ones but I'm low on cash right now. I'm just worried I'm gonna launch hard at the track and my wheels are gonna fall off.
