Ok Guys, what do you think....
Want to get a racing tranny for my track car with Sebring in mind. What's the best set-up? Is a LSD a good idea? Quaife? How about a cooler? What's an intermediate plate?
Thanks for the all the help, I'm really green with trannys. (IMG:style_emoticons/default/biggrin.gif)

A tailshifter can be converted to side-shift, but for the amount of money and work involved, I never could understand why anyone would.


The Only reason to do one is if it is a 914-6 Tail Shifter - you want to keep the Correct Case Numbers & the different Gearing

To comment on the option that Brant mentioned to use a locker diff ... I have one in my 914/6 racecar. I have been happy with it, and plan to continue using it instead of a differential. There are a couple reasons to not use a locker though:
1. If you ever intend to drive the car on the street or autocross it - cars with lockers don't like to make sharp turns AT ALL. I'm talking about the kind to pull in your driveway, park, etc. This is not an issue on the track.
2. For lower horsepower applications, the scrubbing of the inside tires that you get with a locker probably eats horsepower. For a momentum / lower horsepower car, you wouldn't want to give up the horsepower.
