Cayman R skittish rear end
Discussion
Just by way of background, my previous car was a 2006 Cayman S which had its wheel alignment checked and adjusted on a fairly regular basis.
I’ve had the Cayman R now since December and had a few chances to stretch its legs on dry roads, and I’ve noticed a distinct difference in the way the rear end feels compared to the Cayman S, and I have to say I’m not sure I actually like it, I don’t feel like I can really lean on it in the corners like I could with the S and feels like it’s about to let go much sooner.
Tyre pressures have been checked, and checked again. I realise a full wheel alignment is an obvious port of call but I’m just wondering if the addition of the LSD on the R is what may be making a difference in the way the car feels compared to the S, I’ve heard comments that it can feel like the front is being pushed along sometimes? ? First Porsche I’ve had with an LSD (had plenty of other cars with them) and I wasn’t expecting it make such an apparent difference in the way the car feels TBH.
Anybody with experience - or have I answered my own question...?

geo ,geo ,geo and tyre pressures.
My cars pretty much stuck to the road, the R does though have a stiffer rear ARB and is more tail happy than a normal Cayman.
Not to a point one is scared of it though.
perfect set up to me is still widen the front track 7mm spacers at front each side, move the top mounts to give you -1.2 camber up front, little toe up front if any, stock rear settings and Pilot super sport tyres.
I am still in love with how this thing is on UK roads set up like that. LSD is a low % lock unit so I cannot tell it's there 1/2 the time.
ALso drive with Sport mode on to stop the nanny PSM cutting in at every bend, gives the rear a slight slip.

Thats what I thought. When you have the geo done do they alter the top mount settings for you easily enough? My cars pretty much stuck to the road, the R does though have a stiffer rear ARB and is more tail happy than a normal Cayman.

Odd.
I have a CS but I fitted a Quaife LSD as soon as I got it - I also have a more aggressive set up to dial out the standard understeer so it's a bit more pointy.
I find that I can really feel the diff working when the car is already set in the corner and I start to apply the throttle on the way out. The car actually starts to tighten the line (like oversteer but it's a different feeling) but just feeding the steering out a bit progressively with the increase in throttle and the traction is fantastic out of corners.
I'm not describing it very well

no with the setting I just gave you up front and rear factory. front spacers are a key point to the feel.just look a the 981 wider front, GT3 wider front RS even wider front GT4 even wider front again !

Interesting, i've not seen that done before.
Where do you get your geo done?
OPC did my R, but you need one who will allow you to go to a non Porsche set upWhere do you get your geo done?
Chris Frankin did my Spyder as I added adjustable LCA to go even more extreme.
JZM,PARR or any good motor sport shop can do it, not sure what is in your area.
I've got PS2 (N) all round (as I did on my previous Cayman), fitted by Paragon in December when I picked the car up, done 1,500 miles on them now so should be well worn in.
JZM is actually quite close by to me, so perhaps i'll head that way. I need to get my new exhaust fitted so was going to ask them to do that also.
