They make them for may other cars and even the 260 and 280 and 350Z's but not the 300ZXTT or NA. If we get 30, that will be enough for a production run and we can probably get a wholesale price in the $1,200 range. I will need to send them a complete rearend for 2 months. I am all ears if you know of a source for a geared LSD vs the Viscous or clutch type. I had a Torson unit in my 240Z and it was awesome.
