From the diff to the wheels, are there any improvements available? Excepting the R200 which I know will do the job I have in mind, a LS3 through a 4L85E transmission.

everything is pretty sturdy. that being said the axle stubs WILL break when abused. there is a supplier for cromoloy axle shafts and the axle stubs, http://www.modern-motorsports.com/stub-axles.html . other than that, axles hold up well at 500+ ftlb. your going auto so the abuse wont be as dramatic as a clutch car.Hmmm, Whats next?

What's the go on these now? Any alternative suppliers? I contacted the vendor in this thread and they only have axle stubs for the 240/280zx and not the z31.

Yeah they can, just confirmed for about $800 a piece or $500 if they make ten. I'm waiting to hear back from Mark.
Do 4 more people want to get stubs and save me $600? lol

I also got a reply from Mark Williams Enterprises but sounds a bit hard. Not sure if I'm willing to be the test case for these unless someone here has precise dimensions.

I don't think Satan is running the Z31 rear end anymore. A lot of us are swapping in the 240SX subrame. That Z31 axle stub is just a ridiculous affair to remove and install, why not use a system where the axle goes right into the hub, better alignment ability and more LSDs and diff ratios to play with when running 350Z diffs.

For my purposes the long nose R200 has a service limit of about 500whp which is OK for now, suitable ratios for it are no problem too so that's why the driveline question was raised. Rather than change to a S chassis rear suspension setup, for under 500whp I'd modify the semi trailing arm suspension unless it is certain the S setup would give a low enough ride height. I've played with the S setup before but not on a Z31, getting it high enough up under the body was a impossible then without difficult major body work..

I'm guessing that there is a difference between the capacities of the short and long nose R200's. There have been a couple of recent instances of pinion failure in a road race long nose R200's, the extra pinion shaft length may lead to flex and misalignment of pinion to crown wheel.

On the subject of high strength stub axles, I may be interested in a group buy.
