I currently have a stock ride height 95 Cobra with 275/40 x 17s.

Coil overs for the front are on the way within a week or two. Likely going to see about a 1 inch drop on the car once the coil overs are installed.

Eventually I am regearing the car to a 3.73 or even a 4.10 and I'd like to run a slightly taller tire than I am now. Same aspect ratio/width but only on an 18 will give me about the one inch extra diameter I am looking for.

Any serious issues by going with the slightly taller tire? I know that my current size is around 25.6 inches which is slightly smaller than the original stock tires. If I go with my planned 275/40 x 18s it would put me about 1/2 an inch over the original stock tire diameter.

yes the 275/40-18 is too tall ... run a 275/35-18

Are you upgrading from the 17" rim to the 18" rims?
If so, what width are the new 18" going to be?

9s for the front, possibly all four corners. Slight chance of running 10s in the rear to go 285/40x18.

I'm looking to run 3:73 to maybe even 4:10. If I run a 4:10 then I want the larger tire diameter on the rear.

I'm looking to stay right in the 26 inch tall sweet spot for the front. So maybe even going 275/35x18 front but step up in diameter and stagger somewhere between a 285-295 on a 35-40% aspect ratio on an 18 for the rear.

The 17x9 03 wheels I have now would be used more for track day wheels with same tires on all 4 corners, that is until I can get some much lighter wheels. Staggered 18 inch setup would be more for street, mileage, and the drag strip.
