Re: Lower Springs verse Coil Overs???
The reason you have the gap there between your tires and the fenders is this, your tires aren't as tall as the stock ones that came on your car! Might be hard to beleive, but I bet if you measure the tire height on the stock wheels and tires that came on your 05 you will find those low profile 18s to be shorter than your stock ones, and you also probably messed up your speedometer at least some. You might have to buy a chip to fix that. I am former Air Force, Supply, Mat. Facilities Spec, Feb 70 til Apr. 73, don't envy you being in Alaska man!
The stock GT 17s that came on my 06 pony pkg have very little of that gap at all.
