So now that I have decided on what I want to do....More help needed
 

So now that I have decided I want rims and tires....
What size rim can I run?

Will 18x9.5 with +50mm offset fit?

What size tires can i run?

id go 17 X 9.5 for better perf... but...I think u can run upto 315s

But what i need to know is will an 18x9.5 rim fit on my car? all 4 corners

anything can be made to fit with a big enough hammer. Not positive, but I think you'll run out of clearance on hard turns at speed (when the suspension compresses, and near the lock) which is really hard to see, but can be dangerous (wear a hole in teh sidewall of your tire while running a curvy road at any speed)

to be honest i think 17's will ride amazing compared to 18's. plus tires are SOOOOO much cheaper for 17's.i would do 17" chrome Z06's on your car, but good luck with whatever you choose, it will really make your car stand out a lot more.

The 18X9.5's will fit without a problem.
