Sam@IoM Posted October 30, 2018 Share Posted October 30, 2018 Hi all, My Cayman R is off to Center Gravity in a few weeks to have a full geo setup done. Has anyone on this forum used Center Gravity before? My car will see track time next year and I can see three possible options: 1. Full OEM geo setup 2. Maximum front camber via the top mount oversized holes with OEM Toe, caster and rear 3. GT3 Front LCA with -2.5deg Camber with OEM toe, caster and rear - Ran these on my racing car and they were perfect but could be too much for the road. Anyone had any experience of the above with a Cayman? I will probably run the car on Cup2s come spring time. Link to comment Share on other sites More sharing options...
Red Square Images Posted October 30, 2018 Share Posted October 30, 2018 Interested in this. Is the car under warranty? Do the LCAs void it? Link to comment Share on other sites More sharing options...
Sam@IoM Posted October 30, 2018 Author Share Posted October 30, 2018 My car is not currently under Porsche extended warranty but I am considering it..... the car passed a 111 point check as part of the buying process. I don’t want to be tied into N spec tyres, standard LCA and standard brakes..... Link to comment Share on other sites More sharing options...
Mk1 Posted October 30, 2018 Share Posted October 30, 2018 Ran my manual CR on your ... `Option 1` set up for road (Michelin PS2 N rated) plus one track day (Anglesey on Cup 2`s). I was happy with that but being my first Porsche I had nothing to compare to. Ran the Cup 2`s on the road for a while, no issues at all. Not used CG but they do come highly recommended. Have you considered using OEM wheel spacers, a friend used them on his CR and spoke well of their benefit - including max OEM front -ve camber with parallel front toe., not sure on the rear set up but would assume max OEM -ve camber with slight toe in. I assume that you`d be driving to the track events, ultimately ... the limiting factor ? Link to comment Share on other sites More sharing options...
Founder Beanoir™ Posted October 31, 2018 Founder Share Posted October 31, 2018 I’ve run different geo set-ups on different Caymans to ultimately achieve the same result. On my Gen1 CS I had OEM + a slight hint of -ve camber which was enough on that car to remove the understeer enough that I could then lean on the car more and steer on the throttle and have the car move around me nicely. In OEM setup the CR didn’t do that at all and I remember hating the factory dynamics when I first got the car. Small tweaks didn’t cure it either as they did on the CS. I ran a hybrid of option 2 but achieved 1 -ve without enlarging the mounts (although I would have no problem doing so if needed), along with 7mm front spacers to widen the track. Anybody running a CR in OEM geo is seriously missing out! I personally don’t see the need to add more camber than that to a Cayman if being used for road purposes and track days. If you’re planning to race it then that’s a different story altogether. 1 Link to comment Share on other sites More sharing options...
Dougle_turbo Posted October 31, 2018 Share Posted October 31, 2018 How much do C of G charge for a geo set up? My S is due for a 4 wheel alignment in a couple of weeks and wondered how it compared to a specialist's price. Hijacking slightly but Beanoir can you recall your geo setup on the S?

Sam@IoM Posted October 31, 2018 Author Share Posted October 31, 2018 Thanks for the feedback, I have been quoted £340 to have the following: Test drive/Initial assessment Health report of suspension & tyres Geo set up with vehicle massed up with drivers weight Final test drive. Does anyone know the part number for the OEM front wheel spacers? Are longer bolts needed too? I think I'll get a set ready for the geo set up.

MJ Posted October 31, 2018 Share Posted October 31, 2018 will watch this with interest. CoG come highly recommended. I met Chris at Oulton park earler in the year and he's a total enthusiast....and honest! I enquired about spending a day at his for my old 911 but he said he'd follow me round for a few laps and see how the handling looked. He told me the car looked spot on and didn't think it worth the long trip up for me. Not many firms will talk you out of giving them more business!

Interesting you mention spacers, I've read differing options on them. Am I right in saying the conscientious is front only (factory 5mm spacer)? Or is the recommendation 5mm all round?

Depends what you’re trying to achieve, but to help eliminate understeer you want a wider front track - so front only 1 Link to comment Share on other sites More sharing options...

crafty1 Posted November 1, 2018 Share Posted November 1, 2018 Centre Gravity fitted and set up my Ohlins. They not cheap but it's an education in suspension and set up if that's your thing and worth every penny imo. Link to comment Share on other sites More sharing options...
Peopleandcars Posted November 1, 2018 Share Posted November 1, 2018 (edited) Interested in knowing what you end up alignment wise On p9 hear a lot of max caster, camber F -2.5 R -2.0, zero toe front, 1/16 toe in rear from various enthusiast/instructors And -1.5 -1 if also street You'll probably need adjustable front lca for the first and maybe also to reach over -1 front?

Sam, I have 4 x second hand OEM 5mm wheel spacers that I picked up a while ago. Looks like its only the front that are required for a Geo setup. If you wanna buy 2 off me send me a PM. Not looking for much. 1 Link to comment Share on other sites More sharing options...
