1. Given available tire sizes, you wont do better than 305/30-20. The next size up to retain a similar diameter is the 345/25-20. However, it requires a 12"-13" rim.
2. You can't use the 10.5" on the front at all since it pushes the face more than 33mm outward. Close to an inch of tire would not be covered by the fender.

A 56mm offset would give you the 15mm extension you are looking for.
Agreed: a 4-square tire/wheel application ( same size all around) is not necessary and only looks good on cars that have no accentuated rear flares like the F-Type has. (My C4 Vette looked good with 315s front and rear). If you want to increase the front wheel/tire dimensions proportionately to the 11.5" rear with 305s, I would suggest using 265/35-20 tires in front. That will closely match the diameter of the 305/30-20 rear tire and can still be mounted on your proposed 9.0" rim.

info - crisp
Ferrada Wheels FR2 20x 9.0 5x108 et35 Matte Black w/ 265/35-20
Ferrada Wheels FR2 20x11.5 5x108 et30 Matte Black w/ 305/30-20
Pilots and the extra inch should greatly improve handling in the sloppy rear since i don't have 4wd!
You guys are the best!

I know, practice "don't go nuts with the throttle", but on anything but a perfect road I find I can't get into full throttle in the first gear until 5000 rpm or so. I don't think I could improve rear traction any further without heavy mods since I already have MPSS. Any tricks for getting faster into open throttle? Am I being overly conservative and should let the rear slide a bit?
