I am about to install a set of KWv3 coil-overs on my 997.1 and am trying to gather some data for suggested/recommended compression & rebound settings.
I will do the install myself (I like turning wrenches on my cars - it is a bit of a Zen thing: becoming one with the car...) but I will have a professional corner-balance & alignment done right after.

I can do a lot of trial & error settings until I find what I like, but it would be nice to have a recommended place to start - to save some effort and time.

I have heard things like "set the front softer to reduce understeer" but is that true?
Is there a guideline as to how close the compression and rebound settings should be to each other?

My car is my summer DD (so ride quality is a factor - this is not a race car), mixed with eight or more track days per year.

Any experienced advice will be appreciated. (I will also get advice from my trusted and experienced 911 shop, but I like more than one opinion).

Thanks,
John

 

Hi Johnstoy,

As a Premier KW Suspension Distributor/Dealer, we have a fair bit of experience with the product line, more specifically the Porsche Line. I would suggest running them without any compression or rebound adjustment to start.

KW presets each V3 with what they consider to be ideal all around settings. Each damper is dyno’ed before it gets packaged to make sure it is within their spec. The preset adjustments are derived from extensive testing on their state of the art Formula One 7 Post Chassis Shaker Rig.

That said, I would set your desired ride height and run them as they are to establish a baseline, then fine tune from there.

 

johnstoy,

I've attached some scans I've made of the KW installation guide for the 997.1. As you can see, KW provides you with a recommended setting for normal daily driving. From there you can adjust the settings to your liking, but in my experience, most people are very happy with KW's recommendation. The bottom of the second page explains how to achieve those settings. It also explains how each setting will translate into "feel" when you're driving the car.

 

Thanks. FedEx just dropped of the package (my wife sent me an email) but I haven't seen it yet - so I didn't know they included recommended settings.
This should be fun.

Thanks,
John

 

+1 on leaving the settings of the KWv3 the way it comes out the box, KW sets them at the ideal setting, anything after that is personal...I have mine set at KW settings out the box and I love it... but unlike the kw settings my car is a lot lower than they suggest...I think 6turns
