You are going to be limited on your front camber adjustment (more negative camber), unless:

1. You install lower control arm offset bushings (or use adjustable lower control arms)

2. You install some type of camber adjusting plate in your front upper control towers. I use Ground Control (along with their coilover kit) in my '73 autocross car, but there are many other options available since I did the conversion 10 or so years ago. Ground Control was the only player at the time.

3. Rear camber is not as important, but it helps.

Going back to the LSD option, I found this OBX on e-bay from what looks like an authorized dealer.

I think my differential is an R200 out of a 280zx so I'm assuming this unit will work. I understand that I'll need some ancillary parts like shims, but I can use my existing axles. I've been reviewing the following youtube video which seems informative (how did we survive pre-youtube?).

Honestly, I have no idea!!

The OBX LSD ebay listing indicates that it fits the 84 to 89 300ZX. As far as I can tell, I have a R200 out of a 280zx so it should NOT fit my differential. But, from what I read in a posting here on ClassicZ is that the difference between 84 to 89 R200's and the 75-83 R200's is that the 75-83 R200s used a ring gear bolted to the carrier with 10mm bolts while the ’84-89 used 12mm bolts.

In the video by Stewart Motoring, he had used bushings to fit the 10mm bolts into the 12mm holes.

Does that mean that all I need to do is purchase the same bushings he did from McMaster Carr and that will adapt the LSD to my ring gear? I'm assuming that I can retain my existing side shafts or half shafts (whatever they are called) between the rear wheels and differential.

NEW TWIST: The vendor shows the OBX unit is out of stock but he has MHP LSDs at the same price.
