Back in 1989 how old where you? How many cars had 18" rims standard? What was the stock OEM Hp rating for the car? Ok, fast forward 10 years +. How many of us are running stock cars? How many do you think have tampered with your so call engineered theory of the cars original platform? It's not an "intellectual" argument. You wanna drag race? Use your OEM rims with a high sidewall. For the track use a 18 rim with a 30 or 35 series. Or you could say every Top manufacture's wrong I listed and just do as you like. Pretty much the norm here anyway. Bickering, when I simply asked you a question up top.
