If you have to mod it to make it good, just buy the one that's already good enough (gt3)
On another note I pushed the sports button today on my car - quite a difference in steering feel. I am a happy camper. There is still a slight faux feeling , since the steering is not mechanical anymore, but on Sport the heft is back the way I like it. Happy camper now.
