my 96 GT 5 speed has 4.10 gears installed. never been to the track yet. trying to figure out the optimum diameter for track use for 15" rim. I don't want to be redlining at the end of the track since my car makes no useful power after 5500 rpm. any advice? 26" or 28"? 28's look badass but id rather get what I need for lowest ET possible. thanks guys!
