I have a pro kit with 18x9's all around with 255/35/18's in the front and 265/35/18 in the rear and I have too much fender gap so you should be fine.

 

Awesome, They said that the 35 isnt that much difference with the 40 series??? Ok then, thats good to hear. Thanks bro

 

I think when I was getting tires the 40 series was 1/2 " taller then my 35 but i can't remember for sure.

 

That is a good amount of tire still huh??? if your going to work at tire place, at least know what your talking about... LOL Oh well just as long as i get what i want. To returns

 

245/40/18 should be a 25.7" tire(stock height). the 275/40/18 should be a 26" tire. both will be fine even if you lower it some.

 

Your rear tires will be around 26.66" tall, so almost 1" taller than your fronts. Still, they should all fit. I have a 285/35/18 in the back on a 10.5" wheel and roughly a 2" drop with no rubbing. I've also had up to a 275mm tire up front on a 9.5" wide wheel (any wider and you are going past the fender lip) with just slight rubbing at full lock. So it can be done..

 

Jeremy, I have yet to see pics of your car.I woant to see it as it sounds awesome.Can you post'em?

 

Yes, let me dig some up. It looks like crap because the clearcoat is peeling and I haven't gotten around to painting it.

 

Here's a pic with the hood up, it doesn't show the bad paint too much. The only thing different about the car now is the charge pipe you see under the passenger fender is now painted black and tucked up a bit further. Anyway, I think the wheel offset is about perfect.

 

That looks sweet bro!!! Yeah thoes wheels do fit perfect.

 

Looks like I'm going to have to head over to Sparks sometime and take a better look.Maybe1 of the times I go to Summit.
Sorry for the hyjack Ramair.

 

Thanks guys. I've had it for over four years now and I'm still not done.. heh.
