It's personal preference. I tried to run my softer, but there was just not enough body control.

Definitely a better ride on the softer settings.

I have come to the conclusion that there are at least three things that you can't use forum refences for. They are just to subjective.

1. Suspension settings
2. Tires
3. Brake pads

All three things vary a lot by driver ability and preference and on a forum, you have A LOT of different skill levels and preferences.

Yes Mike. Give that a try and give it some time too to get yourself oriented with the car that way. At least 2000 miles or so. Dont let your first impression about the softness fool you. Softest setting is more comfortable than OEM suspension and yet much firmer with significantly more feedback for the driver.

PSS10 is a very sophisticated and well tuned system. The car will behave well on softest setting even on aggressive driving.

This is but here is a pic of Garming GPS showing 313 kmh (195 mph) driven LEGALLY on a public road on the lower right corner...

 

Guy- I also find it very interesting that you use the softest (1) settings on the PSS10s. I may give that a shot and see how she feels. Whats the risk? Nothing... I will just turn the **** and stiffen them up. No prob!

Also, you are crazy for driving that fast!

 

Thanks Steve!

Even a smooth autobahn will be bumpy on high speed. With good tyres, alignment and suspension 300kmh is really not a big deal. Our cars were made to handle that. Even for prolonged times. It feels safe and the car goes straight, no need to squeeze the steering wheel. The aero dynamics downforce start to work its magic after 160 kmh. I think this is the difference between a natural born supercar and a high powered family car (M5, RS6...).

It all comes down to aerodynamics and suspension wether the car is safe to drive fast or not. You NEED a significant amount of downforce and a good suspension to keep you on the ground at the speeds that will take 735.000 pound Jumbo Jet off the ground.

 

Actually our cars aren't that good at downforce in standard trim at all. I would say the faster you go in 911 the less surefooted it feels until you learn to trust the grip. Due to rear engine there is no room for under tray diffuser to generate serious downforce. This means our cars achieve zero lift but no real downforce to speak of. Hence the floaty sensation at speed. All our spoilers amount to is 40kg downforce which merely equalises the lift. This is why you see ridiculous wings at Porsche Cup series racing. If you look at Ferrari for example, the under tray diffusers are responsible for majority of downforce and is what generates its 200kg of downforce above 200km/h. I have taken some high speed sweepers at 300km/h and I was definitely thinking I need the big F/O Porsche Cup wing, should I be doing this often. ;-).

 

Wow... I havent driven any other car at 300kmh so I am biased. 996tt sure felt safe and on the ground at that speed. I´ve done that many times and did not feel any floatyness.

 

You guys are talking about soft/hard regarding the settings...while that may be the appropriate description for some things..., it is not exactly right for the suspension. The settings correspond to the dampening rebound rate (1 slowest, 10 fastest)...now back to your regular programming.

 

Take some corners on German autobahn on uneven surface at that speed. I bet you won't feel that safe anymore. ;-).

I've driven f430 at 300km/h. The car feels much more planted. You can really feel the downforce at work the faster you go.

 

Wross I think you confused matters a bit by using word suspension instead of shocks?

Soft/hard is appropriate description for suspension (suspension as a whole; springs, shocks and sways). However, you are right if we are talking just about shocks - then it is all about rebound rates.

And guys don't forget pss9's are reversed to pss10's.

 

Running 4/4 on my Pss9s and it fixed the bobbing in front. I would like to try 1/1 and see what that feels like as well.

 

Very interesting read. However, I was under the impression that since our engine is located in the rear, we should set the rear to harder than front, in order the support the heavier back? any thoughts? I used 4/3 (F/R) previously, and found it to be too soft especially in the rear during cornering, just switch to 7/7. good in handling during smooth roads, but abit harsh in bumpy road.

 

I'm set to 7F 10R for street and track.

 

My PS10's are set at 2 in the front and 4 in the back.
This is stiff enough for the street and several DE track events a year.
My car feels better in turns if the back is several notches higher than the front.

 

Stock sway bars or aftermarket?

 

Stock sway bars for now.
Tarrett front & rear sway bars are my next mod.
