Saxofonist Posted December 13, 2016 Share Posted December 13, 2016 I am a newbie. In the process of building a Velo Rossa out of a 240z. I have a R200 open differential already installed, but the driveshaft is not in yet. I have a racing buddy, who has an extra limited slip R200 differential that he wants to keep, instead of sell to me, as he may need a differential in the future. He locks his differentials, to the point that one wheel will bounce when you take a slow turn. Is there any reason my friend would rather lock up a limited slip diff versus an open diff? I would assume it is way easier to weld the open diff than to weld the lsd. Your thoughts? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 13, 2016 Share Posted December 13, 2016 You can shim the LSD tight. That's probably what he's doing. Either that or running it without any additive. They chatter really badly without additive. This thread has more on shimming. http://forums.hybridz.org/topic/27605-r200-lsds-and-breakaway-shimming-done/ Quote Link to comment Share on other sites More sharing options...

Neverdone Posted December 13, 2016 Share Posted December 13, 2016 You can't unweld an open diff. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 13, 2016 Share Posted December 13, 2016 LSD > welded for autocross, road racing, sporty driving, etc. The tighter you shim an LSD the more push you get, but you can get the traction with a lot less push out of the LSD vs a welded diff. 1 Quote Link to comment Share on other sites More sharing options...
