Dogbox For the S2000
I have a guy here in Gaithersburg, MD that is a dealer for Phil pfitzner gears in austrailia and he asked me to find how many people would be intrested in getting a Dogbox for the S. He just told me today that they will be designing one for him in a couple weeks as soon as they get the trans from him. But we are just looking for general intrest and possible buyers for the set when it comes out.

Before the question is asked (pilfered this explanation from another forum):
There are two types of engagement: Synchro and Dog.
Synchro engagement (also known as synchromesh) is what most passenger cars use.
Advantages:
a. Smooth operation on the road
b. No special driving style required
Disadvantages:
a. Synchros and shifting forks can break when abused and shifted aggressively
b. Slower to shift vs. dog engagement
Dog engagement is what most race prepared vehicles use.
Advantages:
a. Engage at any rpm
b. Allows for wider gear design
c. Will flat shift (Flat shifting is a practice where the clutch or gas do not need to be totally lifted in order to shift. Users will slightly lift one or the other to unload the dogs to allow a very fast shift)
Disadvantages:
a. Difficult to drive on the road
b. Recommended only for race use
c. Special care required under normal street use
What is a dog box? A dog box is the term for a transmission utilizing a dog engagement. A dog box can have either helical or spur gears or both.

I'm certainly interested in the progression of this as well. My car isn't a completely dedicated track car, but is more and more purposed that way.
My transmission grinds worse than Brett Favre's knees, and as I've been contemplating replacing it, I was wondering if anyone made dog ring gears for this application.
Keep us informed please.
