Default 255/40r18 fitment, I need more gear

I'm thinking of upgrading my 2005 wrx to an 18x8.5 wheel and 255/40r18 tire. I am on Kw variant 1's. I have a close ratio ppg gear box that I feel is too close now that the motor is built. 3rd gear tops at 86 at 7k. I need more gear. I'm wondering if i go with an 18.8.5 wheel +44 or 48 if i will have clearance issues on the coilover side. Fenders will be rolled.

Any particular reason for only stepping up to a 245/40?

Because it's taller than stock, but not 255/40 tall....which is tall.

Thinking of going with a 17x8 or 8.5 wheel and some 245/45r17's instead. Same od as the 245 40 r18's I will be stepping up from a 225/50r16 on the stock wheels. Will a good performance summer tire in this size still handle well and not feel mushy?
