The gt30r should make for a much better street car. Like speed said a more useable power and. But vdubkilla uses 35r with a huge ar. He made well over 500 on race gas. He also used it to tear up mustangs from lights in OC. So his car did well on the street too. I guess it's about what you want as the end result. Is this a street car? Or a strip car that's driven on the street sometimes.
