Default KW Coilover - Hello mouth guard!

Proud and happy older owner of 987.2 2011 Cayman S. Bought used this came with the venerable KW coilover kit (probably type 2?).

It handles beautifully and is to die for lowered about 1.25”. Problem is, for these old bones, if I hit the wrong spot in the road (not even a real pothole), I need a mouth guard. Feels like I may break a wheel or a tooth.

As I contemplate options one savvy friend suggested that the car may have been set-up with the most aggressive springs possible and might benefit from a different spring rate. The other possibility is that I need to go back to factory.

Where can I find the right answer? Also, a young gun might really want this and be willing to trade for OEM.

I’m clueless so seek your advice before I need prepare to look for dentures which I will surely need of I don’t get a little relief

I'm curious to know which coilovers you have as well. If you're located in the California bay area I'd be willing to trade! I drive an 09 base cayman with 28k miles.

Alas, I’m in Georgia. For others who might be interested or if for some reason you don’t mind your car being un-drivable while we do cross country swap let me know. My type was confirmed by KW as V3.

The tendency with most people is to over lower their car, which limits travel, increases preload, and makes the car absorb very little. The V3 has a lot of adjustability for compression and rebound. You might start by raising the car to a more normal ride height, and softening up compression and rebound a bit before you decide their fate. Ultimately the X73 kit from Porsche is the best suspension setup available for your car in terms of a sport suspension without being jarring. It's not expensive and includes beefier anti-roll bars, struts and springs, all engineered for your car. It was the sport suspension option for your car, and lowered the car 20mm from standard. That base Cayman suspension is not X73 and is the polar opposite of what you have now. You would notice a lot more body roll when cornering and the car won't feel as sharp.

Adjust to the softest setting and see how you like it. You should be able to do that by hand and without removing tires. Check KW website for instructions.

Thank you for your reply. Would you have a suggestion for securing a quality used X73?

Would you have a suggestion for best way to secure the X73 (quality used)?

I have both a X73 suspension (12K miles) and a KWv3 suspension (1K miles) that needs a new home. Both removed from my 981 GTS w/PDK.
Just upgraded to JRZ Pro3 plus a lot more.

987.2 is very different from 981 - sigh

This.

I have KW v3s on my 987, and in the stiffer settings it can be jarring like you describe. However, if you adjust the to the softer side, it can be surprisingly compliant. You can definitely tell the difference adjusting by only a few clicks either way, so play around some and you'll probably be able to find a more reasonable setting.

That’s the plan - I wish I could do it myself but I fear need to enlist a pro setup guy

^THAT and also consider the state of the tires.

Old tires get crusty and hard, which can affect the ride considerably. If they're old and crusty its time to replace 'em anyway.

New softer rubber can make a huge difference. Something more along the lines of luxury performance tire.. Like Nitto Invo's.
I think the P-Zero's on my Cayman are too soft and cushy.

I'd look at new rubber first and then take it in for the coil over adjustment.

Thank you - tires are Bridgestone R71Es (I think) and fairly new. I don't need to upgrade right now, however, will probably go to PS4s when I do. I will look at your options when its time. Hopefully, I don't have to go to 18" wheels to make the ride tolerable - that's a last resort

RE71s have a very stiff sidewall - ask any installer about the challenges mounting and unmounting, even in a 19". Assuming you aren't tracking, I would replace with PS4s then sell the RE71s - there is always someone looking for them since they wear so quickly (but provide awesome grip on track).

Drive it for a bit on the new tires then have a shop adjust the coilovers if needed. You should not have to suffer a jarring ride, just needs a few inexpensive tweaks to get there.
