I don’t want to ha e to do a bound up dogleg down shift creating turn 16, which is off camber decreasing radius with an entry of 120+ Mph. It’s also not like there are a lot more wheel options in 18. The goofy offset up front makes for very few options. One of the great things about the 350 was 18x10.5 on stock suspension, cheap light available.
