So I'm looking to perhaps shed some unsprung weight. Problem is If I go down to 18's I can't hit 130 in 4th which will throw off my 60-130 data because ill need that extra shift. That is only true with the stock 245/40 tire size. Now if I go to a 255/40/18 will that give me the ability to hit 130 in 4th? With stock 18's we are hitting 129.96 in 4th.
Setup I'm looking to do.
18x8 Enkei RPF-1 with 255/40/18 Michelin Pilot Super Sports
