I totally need big n lils with my manual rack goodness. You can has my Zr1's with the red lip!!! 17's should raise you up enough to lower it more.

I dont see how its that low and not scraping everything. It looks like we have the same exaust and mine scrapes on the hwy right now. The rear of my car is lowered but the front isnt. My buddy had to run mufflers on the header in order to not scrape when his car was that low. IDK, maybe the LT1 header's are higher?
