PMGPete Posted July 20, 2018 Share Posted July 20, 2018 Has anyone l fitted one, in particular to a 2.7? What brand did you go for and was it worth the spend? Link to comment Share on other sites More sharing options...

Draven Posted July 20, 2018 Share Posted July 20, 2018 I guess the real question is whether you ever find yourself feeling as if you're spinning the inside wheel up through the bends. 1 Link to comment Share on other sites More sharing options...
PMGPete Posted July 20, 2018 Author Share Posted July 20, 2018 Thanks @Craiglm68 I will have a good read through that. @Draven I have always had M cars (still own a v8 M3 alongside the Cayman) so I like to step the tail out a little when the notion takes me and the Cayman is very snappy with the open diff.

Fair enough - but you've obviously got a lot more power and a front engine setup with the M cars, so you'll be making use of the diff far more. Don't get me wrong, I have nothing against diffs, I have one on mine, but in most cases I can't see the lack of one being a problem on a 2.7 Cayman, unless you're intentionally trying to break traction, which is appears you are, so I'll stop interfering and let you track one down now ?

Founder Beanoir™ Posted July 20, 2018 Founder Share Posted July 20, 2018 Cayman’s are certainly not snappy in any form unless something is either worn, broken or not set up correctly - often the latter. I found little benefit in having a factory LSD on a Cayman (however I drove it - track, mountain roads or pissing rain) over one without, but I did really dislike the added understeer it introduced. Mostly overated on Caymans. Aftermarket diffs are available for the Cayman and would probably perform more aggressively, but still I struggle to see how it would really be of benefit in a well set-up and driven Cayman. On something like say a Nissan 200sx with all the weight at the front and barely anything over the driven wheels an LSD has definite benefits to traction. I have one on the M5 and you can actually feel it working sometimes, but again it’s a car that needs it through high power and lack of inherent mechanical traction. That said, what keeps that car on the road is the other electrical gizmos more than the diff. Link to comment Share on other sites More sharing options...

crafty1 Posted July 22, 2018 Share Posted July 22, 2018 (edited) I am not sure of options for the 2.7 / 2.9 Cayman but I agree a LSD would be nice, I think it was Walter Rohrl who said the Cayman would be quicker than a 911 with a LSD, which was part of the reason Porsche did not fit one. From the research I have done the factory fit LSD available on the S and standard fir on the R is not of great quality and wears out, I have heard good things about the Wavetrac TBD (Torque Biasing Diff) which is a fit and forget item with a lifetime warranty. For sure LSD can induce some understeer but in my past experience it can be mitigated to a degree by set up and the understeer was generally only in slower tight corners where the car had a tendency to push on, but get the car rotating better into slower corners and the drive out should more than compensate, I will be fitting one. The only slight problem with attempting tail out oversteer fun in a Cayman is the PSM which cannot be fully turned off plus mid engined cars tend to want to spin easier once sliding but makes for a challenge. Chris Harris looks like he enjoyed the R in this video against the BMW 1M, it would be impossible to do that in my open diff S like mine.

PMGPete Posted January 23, 2019 Author Share Posted January 23, 2019 Yes would love to hear thoughts from someone with an aftermarket diff. My cars about to get the GT3 master cylinder plus better discs, pads, fluid and lines. LSD is one of the next things high up my list Link to comment Share on other sites More sharing options...
crafty1 Posted January 23, 2019 Share Posted January 23, 2019 Not yet fitted, I have been struggling to find someone locally to do it at a half sensible price, but hopefully this month I will. Will let you know once done. Link to comment Share on other sites More sharing options...
