I guarantee with shorter gears, you will pick drop your ET and pick up MPH... As long as you can get it to hook, you will notice a huge difference.... Trust me I have run just about every tranny combo and as for OE, this one and the straight GSR are the best.... Its just that equal medium between the quick accelerating short gears of the B16/ITRs, and the top end of the LSs... It's damn near smack dab in the middle....
