The better the quality of the damper (think shifting large amounts of oil through high quality (ie precision) valving quickly) and the better the matching of spring and damper rates) the less low ride heights will affect the ride/compliance.

With road suspension compliance is king, and keeping the available amount of travel to the maximum will improve your chances of getting decent compliance. But by the same token, you can have all the suspension travel in the world, if your spring and damper rates are wrong/out of kilter, it'll never ride nicely !

Well I wouldn't consider KW V3's "exotic" or indeed any dampers of that ilk/price point either smile

But I digress, this owner :

http://www.planet-9.com/987-cayman-and-boxster-com...

has fitted a B12 kit and looks to have experienced a drop of nearly 2.5" on the front, not sure how much travel there is at static ride height to the internal bump stop coming in to play, but either way, that's a big reduction in travel unless the shock body is shorter and the bumpstop engineered to allow similar amounts of travel as stock.

And please don't think I'm questioning your sanity, but 2 years ago and what 40k miles ? could you be suffering from "rose tinted glasses syndrome" in regards to the Box's ride at lower ride heights ?

Either way, worth giving Chris at CG a phone and asking his thoughts, or better still ask him if you can drop it in so he or Peter can take it for spin ?

Just wanted to say as someone beginning to line up the possibility of buying a 2006 - 2009 Porsche Cayman, this thread is invaluable and great fun to read!

Loving the photos especially. Beautiful car.

I don't think it's acceptable for the front to be so much lower than the rear. I purchased Eibach springs on an Ek9 that were like that, the car looked daft so I sent them back.

Also reading with interest.
I increasing dislike the slightly vague and squishy front end of my Boxster. Throwing in £20k+ to change to a Spyder seems pretty unjustifiable, so wondering if there is another way.

Me too - although the title "bore score edition" does nothing to belie my fears over potentially buying a bad one wink

That does seem super compressed! Have you spoken to Eibach? Maybe send them a tweet, normally gets companies moving!

They are completely coil bound. Either wound from the wrong wire, or not the correct spring at all I would have thought? Have you x-checked the part numbers on the springs?

Yeah, I'd be sending them that pic, that's ridiculous frankly.

Does it have any travel left?!

Must handle/ride horrendously.

I know! It's frustrating as I'm fortunate enough to have the cash for a 987 in great condition and it's everything I want, but this spectre of bore scoring looms large! frown

Where do the spacers you mention fit?

Hi

Sorry if I've misunderstood something...but

Surely that's what's compressing the spring so much then, without them fitted the spring wouldn't be coil bound. All they are doing is preloading the spring, changing the natural compression due to the weight of the car. If the springs are really so much too soft then you're not going top fix the problem this way.

But I think you said, if with the weight off the car you can slip these in between the spring and the top mount then the springs must be too short?!?! Which will be your ride height problem not the spring rate.

I've decided that if I go that route, I'm either going for a later 2.9 (privately), or getting a 3.4 backed by a Porsche warranty. Both around the same price, the former will be the benefit of a newer car though.
I know the whole bore score thing is potentially overblown by internet stories, but it's always be in the back of my head...

Car is looking lovely as usual, slightly odd stance aside chap.

The spring thing is a ballache. I had fund times working out what to do on mine but went to Ground Control in the end as they were helpful in giving recommendations on matching Eibach springs to Koni sport yellows. I think you might try route, or better yet some more tasty (expensive) kit from the usual suspect (Ohlins / KW / Nitron etc.).

In any case good hunting - loving the updates , even including the occasional scraped knuckle / other niggles, bravo thumbup

Hi

I don't disagree that the springs are wrong, that's not what I was getting at.

I thought these pads went between the top mount and the strut top. If they go under the strut top i'd say Mikeeb is correct, you're adding pre-load to the coil springs by adding these pads.

If you get no joy trying to return them, i'd just look to replace the springs with some other aftermarket springs.

PS. It's sad to see you being a bit precious and not wanting a debate / argument on the internet. Never thought i'd see you say that, it's your forte! wink

Did I see you this afternoon OP driving along the B4507 near Uffington? I was on my road bike going the other way but if it was you the car looked great!
