Hi guys , have a 09 tt with awe 650s kit and damptronics. Looking at the next step to improve handling without sacrificing the dd comfort( too much) so the car is more solid around tracks . Do i go with sway bars and thats it or switzter package with dsc moudule ? Suggestions and opinions apppreciated.

 

sway bars and tpc module.

 

Sorry i meant tpc but had switzer on my mind . do you the module with sways on damptronics. ? how good is the new module?

 

i personally don't have it on my car yet (my next round of modding will be in spring).
ive personally met the guys at tpc , they worked on my 996 a couple of years ago, and Mike Levitas (the owner,and professional championship winning driver) was telling me about this module and a little bit about how it worked etc.

its essentially a stand alone computer for the suspension, but it is active...
im not sure if you follow formula 1 (i am a f1 junkee).. back in the day, there was a team that had a "self leveling" suspension, where the car would ALWAYS be flat around corners (all types of corners, low speed and high speed).. allowing it to corner at greater speed...


audi had the same idea back in 2003 when they introduced "DRC" on their RS6 which cross linked the front right to rear left, front left to rear right struts to have the same effect.

there are two ways to get the car to be flat on all corners at all times. you can either control the ride height (hydrolic or air) (thats what formula 1 did). or you can control the stiffness of the shock to achieve the same result (thats what TPC does, because we have coil springs, not air suspension).

mercedes benz has something similar as well, but they use air suspension to achieve their goals... great for a mercedes, not possible on a 911.

youre probably wondering, "isnt that what sway bars are for" ? yes and no. sway bars are adjusted for high speed turns or low speed turns. lets say youre on a track with very tight low speed turns. youre going to want to set the sways as stiff as possible.. but if youre on a track with high speed turns, you'll want sways that are a little softer so the car doesnt snap on you.. thats a passive or "reactive" suspension component.

although TPC hasn't released how their system works (they do have a patent pending on it), i would imagine it they use a couple of sensors (yaw sensor, steering angle sensor, throttle position, and (not sure if this is even possible for our cars) the amount of pressure on each strut at a given time to adjust the cars balance... the fact that they have a plug in unit leads me to believe that it processes data MUCH MUCH faster than the oem unit and can therefore be a true active suspension device...


im not sure if this device is even legal in motorsport teams, as it was banned in formula 1 because the team that used it (Williams F1) would literally be MINUTES ahead of every other car by the end of the race... MINUTES , not seconds.

 

i forgot to ask the obvious question, you have a set of street and track tires right ?

 

Yes, running RE 11 for track but will be purchasing R compound in the future as wanted to try Bridgestone to compare.

 

if you are putting a legit 3000 track miles a yr out of 10k total then absolutely set it up 100% for the track.

 

Re11 are great tires.

 

^ ^ ^ this. Except my guess is that OP doesn't track 3,000 miles per year....but maybe 3,000 including driving to and from the track.


My car will be doing approx 33% track, 33% airstrip, 33% DD. But most of the track and airstrip miles are put on the car actually driving to the events...so the car needs to be comfortable. But it also needs to perform much better than stock.


If you want marginal performance (+10%) gains over stock, then you can do something like the Bilstein coils which allow you to retain factory PASM
so you can DD in comfort and track in sport (pasm on).


But if you want something MUCH better than this, then you have to open up your wallet.


I have other track cars and wasn't looking for a marginal performance upgrade. Frankly I was not impressed with the factory handling at all so I knew (on the test drive) that the suspension needed to be gutted. I ended up consulting with former RSR ALMS race team @ BBI Autosport and after long discussions I ended up with Ohlins single adj coils with BBI end links and LCAs with a corner balance alignment. This set up is extremely comfortable and dramatic improvement over stock as the twitchiness is all but gone, particularly the rear-end and finally feels like a proper chassis. In the few weeks I've had this set up, the limits of the car have been far extended....I will look forward to my first track day.


While my car was being worked on, Tanner Faust's personal 996 Turbo DD was there as well with a KW rep working with BBI on a custom valving set up with KW Clubsports. This would be an even better choice if the comfort goal was achieved. And I understand from BBI that Tanner was extremely pleased. Can't get any better of an endorsement on this forum or anywhere else.


Good luck.

 

The good days of Senna vs Prost!

 

^yea man. those were the good days...
now the closest thing we get to witness is multi 21 lol... although turkey 2010 was exciting as hell to see !

 

Don't think that multi 21 will be needed anytime soon the way Red Bull started with testing this past week!!!

 

yea , tell me about it. i really hope they sort everything out.
look at that rear !!

 

It s the Weber curse!!!!! Wonder if Weber is smiling inside???
