I have an ZX R200 3.9 rear end in my 78 280Z with stock stub axles.
I am looking to put in an LSD unit and think I am down to two options:
1. The Calmini, that I have confirmed with them is a 29 spline.

2. The 240SX NISMO LSD
Limited Slip Differential (240SX 1989-1998 w/o OE LSD) SKU: 38420-RS661

Any thoughts or opinions?
This is a street car (Daily Driver) that I autocross and track occasionally.
Thanks,
Fred
