I bought a gsr tranny w/ a PG cradle for my car... the car is a street/strip car, but I probably wont drive it extremely far on the street. After I bought the tranny I've thought more and more about not having 5th gear (b/c the cradle replaces it)... So, I was just wondering if anyone knew off hand what rpms you turn at 55, 60, 65 mph in 4th gear with your gsr trannies? thanks in advace

 

4,000@60mph in 4th
3,500@50MPH in 4th

 

guess that's not too bad...how tall are your tires? my tires are 26" tall so that should help me some

 

don't know exactly how tall they are but im sittin on 205/45/16 if that helps

 

i think they are like 23.2 and mine are 26.1... I turn mine over about 100 less times in a mile than you, but I'm not sober enough to figure out how many rpm's that would save me
