If I run 18x9's 255 50 18's in front and 18x10 285 40 18's in back is my speedo and odomo going to have to be recalibrated with a tune. and how should car ride with those two different sizes.

 

That's a great question, I just got an order for my 18X10 bullits yesterday, and I'd like to know this too

 

Are you running 18x10's all around? Do you know what tires your going with and what color bullits you going with. I just ordered an 07 gt. in silver with two tone charcoal and light gray interior. Im putting on most likely black racing stripes front to back and thought I'd go with black bullits with 3 spoke spinners and ford center caps. what you doing on wheels?

 

Hey daniel06gt, forgot to ask you about your tint - It looks great - I dont know whether or not to put a side window louver on, but yours tinted looks nice especially if I go with black stripes.

 

If it's different from the diameter of the stock tire then your speedo will be off.

 

I'm going with these wheels that I just got yesterday:

I'm only putting those in the back. I'll keep the stock ones up front and since these wheels look the same style Bullits and color, it won't look funny. I just like the way they look with the big wheels in the back, it gives it a "mean stance". I have been thinking about getting the Roush louvers, Classic design CDC Ducktail and the 10pc 3d Carbon Body kit.
Oh and definetly get those black racing stripes, the same style as the GT500. Although this will come later, i still need to build up my savings account [:@]

I'm running 18x9s in the front and 18x10s in the back also. I checked mile mhp and I'm off by 3mph(used my handy dandy GPS).

 

Ah, that's not bad at all!
It's good to know, and i'm assuming you're 3 mph slower on your speedo right?
Not faster.
