The kit was designed to work with stock wheels and tires, HOWEVER, it seems that something might have changed in the rear suspension geometry somewhere along the lines. I have probably got 300 of these kits out in the market place and I have had 2 issues with stock wheels rubbing the shock in the rear after the install. I have plans sitting on my desk in front of me to try a slight angle adjustment on the rear kit to hopefully correct this rare problem but I have not had a chance to finish it and get it out to my tester. I'm hoping to have them in the mail by Friday for testing, then its just a matter of time before he gets the parts and puts them on his machine.

For the most part, spacers have not been needed, but I wont tell you that YOU will not need them for sure, sorry...
