jkube Posted October 9, 2003 Share Posted October 9, 2003 I managed to finish install of the R200 3.54 diff with the Retrofit Limited slip kit and the modified R180 mustache bar. After an easy trip around the block to make sure none of the bolts were loose. I dumped the clutch at 4000 rpm to see if I could break the mustache bar ( I have NA L28 with Racer Brown 325 cam and headers..I know...not really a ton-o-power!!) So far after several starts like that the bar is still in place and there are no clunks or signs of failure. I did have some fun attempting some drifts in the nearby parking lot!! Now I just need some more power Quote Link to comment Share on other sites More sharing options...
A. G. Olphart Posted December 27, 2003 Share Posted December 27, 2003 So now that you have had your Retrofit limited slip installed for a while, how do you like it? How about posting Retrofit's info? I'd really like to know how these stand up to V8 abuse... any info/links appreciated. Thanks- Quote Link to comment Share on other sites More sharing options...

jkube Posted December 29, 2003 Author Share Posted December 29, 2003 Iv'e installed the Retrofit Limited slip kit into both my car and my uncle's 240z. Both differentials have settled in now. On my car the setup "loosened off" a bit because the diff gears are very worn. It still locks both rear wheels but the breakout force (car up on jackstands) is less. Actually this is a better setup for wet road conditions because there is less understeer going into a corner. During the winter I'll add some shims to adjust the breakout force a little higher. My uncles diff has stayed with a higher breakout force because his diff was in better condition to begin with. He's thrashed his more than I have and its still going well, with no problems. I believe you should be able to use this on your V8 project. This part doesnt appear to be the weak link in the drivetrain system. But you can ask Retrofit yourself about this.

A. G. Olphart Posted December 29, 2003 Share Posted December 29, 2003 Many thanks... I had been wondering about the durability/longevity esp. if a guy spins the tires occasionally at a stop light (not that I would ever do that ). Quote Link to comment Share on other sites More sharing options...
260DET Posted December 30, 2003 Share Posted December 30, 2003 Me too. What does a Retrofit LSD consist of and what limited slip mechanism does it use eg clutch pack? And how much doe$ it cost? Any web sites? Questions, questions............. 8) Quote Link to comment Share on other sites More sharing options...
fl327 Posted December 30, 2003 Share Posted December 30, 2003 Im interested in specs on it as well. Looks like a Phantom Grip, which is more like a mini spool than LSD. R200 already seems to lock both axles just fine in a straight line, its the doughnuts were missing here! Quote Link to comment Share on other sites More sharing options...
