I recently purchased an 03 cobra, and it has silver/grey 18" Cobra R rims on it. Now My problem is Whoever had this car before me put G-force Sport 275/35 Z-R 18" 95w tires an rims all around. Now the front right rubs pretty bad to wear its wearing away at the inside lip of the rim. The front tires are obviously too big my question is what size tires should I run in the front.
I plan on keeping the same rims in the rear so im just replacing the front 2 rims and all the tires. I am just unsure what size to get, also should I put 17"rims in the front with a little more narrow tire and keep the 18's in the rear? Also keep in mind the car is pretty modified it dyno'd @ 515 so Im not sure if that effects what tires or rim size I can put on it.
One more thing is, im getting new tired cause the G-forces just don't hook at all and I would like some suggestions on what brand and style of tire to get.

I'm not exactly sure on the rim size's beside that they are 18's not sure on the width I just have the tires that are currently mounted on it, but the front and rear tires look the exact same size with the same tires. Also keep in mind the care is lowered with a drag suspension.

 

get drag radial, atleast nittos
front shouldnt really rub maybe get a spacer
