Got my 1" bolt on spacers from TonySS. He used to have them on a Malibu g-body wagon that had the same wheels I have. He made me an awesome deal, Thanks again Tony! These spacers were built by Fred at

Before the rear spacers my 5.5" backspacing wheels looked a little too tucked in and the front track width was a little wider than the rear. The photos don't illustrate really well just how goofy it looked but here's an idea...
After installing the spacers- My car will be fairly low so I rolled the fender lips. I had my wife jump on the bumper and it has to compress about 3" before any contact up inside the fender well. I think they'll work out great.
