My 07 GT came with the premium 18" wheels, and appearance wise I absolutely love the wheel. I think they fit the car about as good as one could ask for. One of the things I miss about aftermarket wheels is how their offset fills up the wheel well from the left to the right.

On one of my old FWD 200hp vehicles, I got a cheap set of wheel spacers that IMHO helped out a bit.

For a RWD vehicle making 300hp, I wouldn't want to put the same cheap POS's on there. Is there any wheel spacer out there that will kick the wheels out and be safe for the vehicle without replacing the studs?

 

Good quality & SAFE wheel spacers NEED NEW STUDS!!! Go to Mustang Wheels..........He has great spacer kits. But wheel spacers without new longer studs
I would NEVER put them on my car. your asking for big problems............Accedent just waiting To Happen!!

 

check here, I have run these type of wheel spacers on a 700 rwhp Porsche and a 500 rwhp Mustang drag car with no problems

wait, so when you go up in rim size, say 20's like I have, u need wheel spacers?

 

No, you don't need them to go up to 20's. I need them though for my 18" Torq Thrust M's if I want to upgrade my brakes though.

 

Cool, I can definitely do the longer studs, I've just never put those on myself. Anyone have a quick how to on doing that? I just want to be safe!

I'd only be looking to kick them out 1/3-1/2 of an inch, maybe a hair more, so its nothing major...key is safety, then simplicity :-)
