reverse manual keeps me from trying to grab a higher gear on the track, and hitting nuetral. this may seem simple, you only have 3 gears, right? but when you're on the track, and the adrenalin is pumping, it's easy to try for one more, even though there's only 50 feet to the next turn (where you need 2nd!) i've caught myself several times going for one more. performance would be the same without the idiot factor.
in a street/performance situation, i would install a reverse lockout shifter. then you can't hit nuetral, can shift manuallly nice, and didn't spend the money on a full manual trans.
