"OK, so you've talked all 450 of your horses back to the rear axles, now what will you use for rubber to get it all on the ground?"

I bought one of this the other day just to see the fitment and offset: http://i60.tinypic.com/ric2l4.jpg
Probably I will use 235x35x18 in the front, and 295x30x18 in the rear.
I changed the 4 wheels using Mustang GT 5 bolt pattern and adjustable damper all around.
I widen the body to accommodate big tires. I will take picture of the suspension once i get back from Connecticut.

To simplify how the two system works:
The LSD (POSI traction) works: when one of the rear wheel is spinning (slipping), the LSD apply more power to the same wheel.
Whereas the QUAIFE ATB, is the opposite: When one of the front or rear wheel is spinning (slipping), the system apply power on the other
wheels that its not slipping......which is common sense. Why would you apply power on the slipping wheel? right?

I'm in agreement with the numbers you stated Frank.
That's why When I built the new 355 SBC for my roadster, knowing I
have to resist the desire to race it, it was set up for street use mainly.
With the 650 cfm eddlebrock I figured my car for a lbs/hp of 6.47.
The car is very streetable and I'm not putting any real strain on the engine.
The Tremec 5spd has a .62 5th so it cruizes nicely 2500 +/- for 75 mph.

I'd think the RB with the 5 spd. & R200/quaife combination should be more
streetable than you think. Hairy ........ yes, but only if you get on it.

Hopefully......civilize that I projected. I'm getting too old - my response and vision are fast failing.

s2kseven, I somehow forgot his actual forum handle on z31performance, but I think I found the same guy on zilvia and sent him a PM. Seems like he doesn't check Zilvia as frequently but I will let you know if I hear back.
