Your roads must be covered in dirt (not sure what flat asphalt is...). There is not reason the PSS 255/295 shouldn't be capable on a 414 hp, 295 torque car...
I have some bolt ons and running on 245/275 DWS (not by choice, came with car) and I can drop the car into 3rd and take off in 50 degree weather, no problem.
If you want sticker tires, get AD08s, RS3, Dirreza ZII, RE11s. AFter that, you are talking about track tires, the NT01s, etc.
