docman Posted November 11, 2020 Share Posted November 11, 2020 I recently bought an 06 Cayman S with 35k miles. The previous owner installed Eibach springs & Tarett stabar/drop links with pronounced negative camber. The car sits so low, I can't get up my driveway without scraping. I went on a Porsche club back road run and I spoke with another member with a Cayman S that was running Cayman R suspension. Supposedly that drops the car 20 mm but his sat as low as mine. I'm considering going back to factory standard springs to stop my car from scraping. I also checked my tire pressure today and it was pretty much 22 psi all around. Even at that low a pressure the Eibach springs gave a rock hard ride. I'll likely never track my car, it's usage will be daily driver with the occasional back road weekend trip. Recommendations? PASM springs (10 mm drop) I almost prefer staying with OE. Link to comment Share on other sites More sharing options...
Founder Beanoir™ Posted November 11, 2020 Founder Share Posted November 11, 2020 I suspect the problem you have with ride quality is using lowering springs with standard dampers that aren't designed to work with a 35mm spring. Your car looks lower than a Cayman R to me, particularly at the front. Link to comment Share on other sites More sharing options...
Lennym1984 Posted November 11, 2020 Share Posted November 11, 2020 (edited) I have my car lowered on Cayman R springs with B8 dampers and it isn't that low. There is a clear arch gap front and rear whereas your looks quite "tucked" on the front. Based on my before/after measurements, mine now sits ~23mm lower than standard. Provided that you drive carefully, there is no scraping on speed bumps (and even if you don't, it is just the edge of the front flap bits). Mine has a lot of camber up front so looks a little lower than it really is but the arch gap is 2 fingers on front and 3 on rear.

Lennym1984 Posted November 11, 2020 Share Posted November 11, 2020 ...And a Cayman R for reference (not mine...sadly) Link to comment Share on other sites More sharing options...
mc5 Posted November 12, 2020 Share Posted November 12, 2020 From what Ive seen these 35mm eibachs & h&rs arent fit for purpose unless you want a slammed ride. Had a similar issue on my z4m always on the bump stops at the front. I would go oem or r springs or coilovers at great expense. 10mm pasm springs could be an option but will they be well matched to non pasm dampers Link to comment Share on other sites More sharing options...
Ben Posted November 12, 2020 Share Posted November 12, 2020 Mine rides on H&R springs and standard dampers, no significant issues with scraping, and doesn't look as low that Link to comment Share on other sites More sharing options...
banjo Posted November 12, 2020 Share Posted November 12, 2020 i fitted H and R to my old 987 and the drop looked supurb and rode better than stock. have heard of others having issues with the eibach though. Link to comment Share on other sites More sharing options...
Edmundo2 Posted November 12, 2020 Share Posted November 12, 2020 I'm on KW V3 with R geo and 19" rims. I have to say the ride is superb and can be adjusted to your preference. No rubbing on bodywork and no scraping on ramps etc..Well worth a look...( apologies I can't upload image due to size ) Link to comment Share on other sites More sharing options...
Nate Posted November 14, 2020 Share Posted November 14, 2020 I'm about to install H&R coilovers, here is my question..is there anything else I should change? adjustable rear toe kit? drop links? Link to comment Share on other sites More sharing options...
Mavrik Posted November 14, 2020 Share Posted November 14, 2020 (edited) I fitted H&R -35mm springs on my CS & still have a 2 finger gap front & rear... On 18" rims though with 5/15 spacers. I have to negotiate speed bumps carefully & the front nose scrapes a tad on gradients to flat but coming at an angle is fine. I'm on Bilstein B4 shocks & have zero issues (stock drop links/LCA's etc but I've elongated the turret strut mounts for max neg camber) ... I'm running fairly aggressive geo from stock settings...

Defo change the strut top mounts (false economy not to imo) re anything else, if you plan on tracking the car (or fast road etc) you'll want more aggressive geo settings for best affect... You can go the whole hog on adjustable LCA's etc but unless it lives on track then it's a bit overkill imo... Link to comment Share on other sites More sharing options...

Also was thinking about rear top mounts but didn't see any about. My Cayman is purely for road use. Where do people go for decent geo? Centre Gravity is nearly 3 hours away for me :(.

Mavrik Posted November 14, 2020 Share Posted November 14, 2020 @Nate No need to go to a specialist geo centre imo. A decent tyre shop that has the latest Hunter laser setup is sufficient... I paid £125 for full Hunter 4 wheel setup to my own geo numbers... 1 Link to comment Share on other sites More sharing options...

Mavrik Posted November 14, 2020 Share Posted November 14, 2020 (edited) @Nate I'm running 0.01 toe on the front with -1.35 camber & 0.08 toe on the rear with -2.00 camber. If you want a more aggressive front -ve camber then you'll need adjustable LCA's/top mounts (I elongated the strut mount holes inboard to gain as much neg camber as possible) Of course, if you're fitting a decent coilover system, then getting geo & corner weighting done might be more preferable? ... Depends on how deep your pockets are lol... Edited November 14, 2020 by Mavrik Link to comment Share on other sites More sharing options...
Nate Posted November 14, 2020 Share Posted November 14, 2020 @Mavrik thanks for the info Mavrik. That is similar to my S2000 set up only the S2000 has a bit more negative camber 1 Link to comment Share on other sites More sharing options...
