Here's the rest:

The housing. I will state that the tube structures are less than .100" wall thickness, with the actual axle tubes being of a different dimension. Sorry specific details are proprietary, I hope you can understand. All of the tubes for the Watt's location do two things: one, they are responsible for carrying ALL lateral loads and transfering it into the frame via the Watt's link. We do not tolerate deflection, or fatigue issues. Two, this structure, as well as the additional back-bracing creates a very strong (in bending) axle assembly, while allowing light weight materials (load paths considered). So what? Well, one very important thing: axle assembly deflection. Today's tires stick pretty darned good, and in addition, horsepower doesn't seem to be the limiting factor in most cars these days, north of 500 HP is considered normal. These two factors result in one really nasty outcome for a car: toe-out during forward acceleration. Our opinion is that this MUST be avoided at all reasonable cost, especially in corner exit, a toe out condition in this case will make the car tend towards oversteer, so the driver will have to back off of the throttle to let things settle, we don't like that. Okay, that's all fine. What does it weigh? All in, the axle assembly (without axles, center section, or brakes)weighs a touch less than 60 pounds (we can custom make lighter ones for race applications). Add in an aluminum gear carrier from Strange, which is about 14 pounds, and the rear is right around 70 or so pounds. How much does a 12 bolt rear weigh without brakes, axles and center section? Honestly, we don't know, but we are completely confident that there is no possible comparison in overall strength, torsional and bending rigidity.

I am sure there is something I left out. Please be patient with follow-on questions, we are working very hard to get ready for the show, and I cannot spend a lot of time behind the keyboard. I hope that this at least gave you something to chew on (other than pretty pictures), and if you have other specific questions, please bring them on. I'll do my very best to answer them without giving up specifics of the design that others can grab without having to do the dilligence that we went through. Frankly, I live for the tech, and I have complete confidence in being able to describe our design, and why it takes the form that it does, in any level of technical detail. And if I don't know, I'll tell you. If you have a better idea, we would LOVE to hear about it, we thrive on learning and applying new ideas. And please guys, I ask all of you guys to relax, this forum is the best one going right now, I hope we can keep it that way.

Cheers,
Mark

Edit: Added another pretty picture, well, I think it's pretty.
