Quaife has agreed to design and manufacture a Torque Biasing differential for the R230 rear-end used in the 1990-1996 Nissan 300ZXTT!! They make them for just about every performance car out there except our Twin Turbos. I (Randy Roth) have sent Quaife a used R230 for engineering and design purposes. If everything goes well, we may have units designed and built in time for spring racing. HOWEVER, we need to get a commitment of 30 firm orders before Quaife will build the units for us.
Please vote, and email me at rroth@vitex.com if you have an interest in the Quaife LSD. If you prefer to call, my number is 704-663-5858x102.
