Leading evidence: 'Run sticky tyres' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'matter of opinion' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Run on the rears' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Idont have spacers with my 20's, used 15mm H&R spacers front and back when I had my 18's on.

Thanks for posting the Pic's, What size rubber are you running on the rears?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

OK, I have finally bitten the bullet and asked my Porsche tech to order me some Eubach springs for my non-PASM
cayman
.
I know a few people have these. Does anyone care to comment on experiences? How is ride affected on the street? Do you bottom out on driveways?
What about the track? Is there a noticiable difference in lap times due to the lowered centre of gravity, stiffer springs, decreased roll rate and increased negative camber? (My porsche tech has told me that as the car lowers the top of the whells slides in under the wheel arch increasing negative camber).
I run sticky tyres already. I have nearly worn them out after 4 track days. I am now down to within 3 seconds a lap difference between my
Cayman
and the fastest car in my class, which is a full rally spec lowered 996 with cage, GT2 seats, harness etc. This is only at my 2nd ever club sprint so the
Cayman
has good potential.

I would be somewhat wary of this technician. What he says is of course true, but then the first thing you should do on lowering the car (or any mod to the suspension) is to do a re-alignment to correct the camber. Lowering the car without re-aligning will play havoc with your settings.

He will be doing a full alignment. This guy is the most experienced Porsche motorsport technician in Australia from what I have heard. He has only just started taking on reg. customers, as up until recently he only looked after cup cars etc.
Sorry, just me being picky. I had Eibachs put on my 964, and re-alinged by the tech who fitted them, but I still wasn't really happy with the handling. I was then reccomended an alignment specialist, who re-did it taking note of the lowering of the springs, and the difference was dramatic. Hope it works well for you.
John H
if done properly you will love it. To me the ride is just as good,...maybe better than previously. definitely agree with an expert alignment afterwards to correct for the new height (camber and so on). Your ride will settle a just a bit after a few weeks. Not sure if you should have it looked at afterwards or not...may be overkill. Good Luck!...and post some pics for us to see!
I have the Eubach springs on my Kman. I wasn't able to compare it with stock suspension because I had my dealer do the work before taking it home. I can tell you that you have to be xtra xtra careful with alot of driveway. You'll find your self having to go at a 45 degree angle. Sometimes you'll avoid scraping but not always./fckeditor/editor/images/smiley/MWPX/cry_smile.gif
sorry to jump in this thread guys, but i was told by someone that H&R springs are useless and i'm better to stick with my stock springs. this person also told me that, eibach makes much better springs.
is this true?
Idont have spacers with my 20's, used 15mm H&R spacers front and back when I had my 18's on.
As far as H&R springs go....well, I had H&R coilovers on my audi and they were real squeaky. had to have them messed with a bunch of times by the shop to get them at an acceptable level. But I was disappointed with the overall noise they generated. Not sure about the H&R springs alone or the ones available for the
cayman
. Most of the Audi guys I used to talk with said Eibach were better than H&R though. Probably a matter of opinion.
I have H&R's on mine and they have been wonderful. I have heard no pro's or con's of Eibachs or H&R myself. I just read that Eibach now has specific springs for the
CaymanS
. The H&R's that are on mine were actually for the
Boxster
but they fit the same for the
CaymanS
. I believe Red Rocket will say the same thing for the original Eibachs.
BTW, I have 18' RH custom wheels on mine and I have 15mm spacers on the rear and none in the front.
AmerLemans, Can you post a Oic of your car, I'm thinking of putting on spacer and not sure what size? I have 19' carrera sport wheels on the CS and want to push them out a little, I've had recommendations from 5-mm all the way 15-mm ....
Amer: so there is really no difference between the H&R and Eibach?
I keep hearing different stories from different people. i'm really confused right now.
btw, i heard that H&R will get lowered by itself after sometimes using it.

If I had to do it right now, I would go with the Eibach as they are now 'specifically' for the
CaymanS
. Here is a pic of mine with the H&R's and 15mm rear spacers. I think it has lowered a touch even more since this picture. Every now and then I tend to think that it is too low when I look at it from different angles.

With 15mm spacers. I think these particular wheels come with the right amount of offset but I was sent ones with the incorrect offset thus I had to get spacers.

will lowering shorten the life of the stock shock? what should one look for in buying lowering spring that can still keep the stock shock in as if the shock is in conjunction with stock spring?
thanks
Yes - always. If you are really worried about it, the only answer is to buy coilovers instead of springs. I would assume a spring with a rate closer to the stock spring rate (I do not know what that is) that does not lower the car too much is going to give you better shock life than something else, but that would defeat the purpose of doing the mod in the first place.
I've seen some cars (not talking Porsche here) go 12,000 miles on a set of springs before needing new shocks, and I've seen other cars go 50,000 miles - there is no rhyme or reason to it.
