Ok I have a 08gt. Currently have polished ctsv wheels on it. Which I'm trying to sell. But i found a good deal on some weld wheels. I wanna run 18x5 in the front and 17x10 in the back. Using welds website it says the front bs should be 3.20 and the rear should be 7.8. Ive been doing lots of searching and everyone has a different idea of what I need. But I plan on running a 185 in from and 275 Mickey Thompson tires. And I wanna lower the car too. Just wanna make sure they don't rub any. Any input could help with pics. And what springs would be good lol.
