I bought a set of cheap futura ultra Z tires which grab surprisingly well for the 100 bucks paid... putting them on was a nightmare for them though.. I have 17 x 9 cobra r's and the tires rubbed extremely bad... soo they told me if i didnt wanna go back to a smaller tire, then to take my tails off and run 1/4 spacers..... so i bought the spacers and that took care of the rubbing on the quadshock, and they were nice enough to bend my hangers soo my tailpipes would clear... no rubbing now... question is... are wheel spacers bad to use?? anddd will they throw the alignment off? I would assume they wont mess with the alignment right?
