Walter's clicks

http://www.total911.com/interview/wa...e-nurburgring/
Total 911 caught with Porsche legend, Walter Röhrl at the Autosport Show to talk about rallying, development driving for Porsche, and Bilstein suspension.

You had new Bilsteins fitted to your 964 RS. As a test driver, how important is suspension setup in the design process of a new racing model?

I would say that it is the most important thing. On a race track, it is relatively easy to make sure that engines are levelled. So, suspension can give you the only advantage.

Look at the other elements of the car; tyres, aero, brakes. There is no point trying to perfect these until the chassis is working properly. The 964 RS, which I regard to be one of the best cars to drive is a great example.



From the factory it is too hard up front compared to other Porsche models. It has a hard spring and a soft damper. When you change to the BILSTEIN PSS10 kit, you can really make the car drive much better.

When I drive mine on track I run six clicks on the front and nine on the rear. On the road I run ‘three’ front and ‘seven’ rear. Set like that, the car drives perfectly! If you have this car, you should try it!

We need some in-car vids of Walter hustling his PSS10-equipped 964 RS around the 'Ring.

Wow I was only thinking of installing that suspension in my rs this year
I need some comfort....getting old I guess

So is this click from full hard or soft?

On PSS10's the adjustments are labeled 1-10, so no guessing like some damper adjustments where you have to count only by the "click" feeling. Which means on track he is one shy of full hard on the rear. Great info though, not far off how I've run mine which sits on harder than stock PSS10 springs.

Jetta, thanks for sharing. I will be fitting new PSS10's this winter along with RS bars. Great info.

Hal, the dials are numbered. The higher the number on PSS10's the stiffer the set-up. I believe he is referring to "clicks" as numbers. So 3 clicks would be number 3 on the dial. The dial clicks when you spin to the next setting.

Gents, note that this is applicable to all dampening adjustments (KW whatever) as a ratio front to rear.

Love this Röhrl quote:-)

"If you asked me which I thought was the purest drive, I would have to say the 964 though…"

HalV

Thanks! That makes sense. I have KWs and they count clicks from full Hard.

Adding that to my signature...

Walter use's PSS10 on HIS OWN 964RS.

He has had them in it for a while now,he went looking for a black 964 rs around 3 years ago before prices went too high!! Doubt it make the prices go up!

What spring weights is he running? / talking about on the PSS10's

well, he`s a customer of my mechanic with his cars. I don`t know what suspension is in his 964RS, but my mechanic loves - and always recommends - bilstein stuff and dislikes kw.
For pure street driving bilstein pss-stuff should be quite perfect. For some more or harder usage, the street coils are far to soft with its spring-rates. Even if you "close" the clicks on the damper, the spring is still so soft and you drive on the oil-cushion...

I just get original RS-springs with 964 cup dampers in front and 964 RS dampers on the rear for my car during winter hibernation. The 964-cup dampers have the same rebound like 993 RS damper - round about 10% less than 964 RS stuff. The cup dampers are said to be less harsh in the front compared to the orig. rs-stuff and far more sensitive in response.

I`ll also remove the h&r sways and switch back to the 90-C2 setup and not to the orig. C4 setup with 18mm in the rear. I`ll also use rubber top-mounts an no monoballs...

So that would mean he's running a 'soft' front and 'stiff' rear to favor oversteer....which I guess is exactly what we would expect from Mr Rohrl.
