Can anyone tell me what the late 80's Cup Cars were running for front and rear suspension?? Springs, torsen bars , sway bars etc.
Are the parts still available (springs) ?
Were these options anyone could have had when ordering a 951 ?
Thanks

I can't vouch for how accurate it is, but here is a source of suspension specs.

I know that I am part of the minority, but I love my cup suspension on the street. I live in frost-heave land, too. I do NOT, however, drive it everyday.
It is tons of fun

 

Thanks all.
I was thinking of upgrading the suspension. I do some Autox and want to start
doing some De next year maybe. Was trying to see if the turbo cup springs
and rear helper spring setup could be considered a factory option. Thinking of running stock class solo2. Guess it doesn't matter if the springs aren't available
anymore.

 

whats the relation of the escort cup and the actual cup suspension? thats the suspension I'm after, is it the same setup? is it better or worse?

i dont think that escort cup setup is as mild as you say... did you take a look at it? I'm no expert however, and considering your name, you might be right? it seems like they are sold with heavy valving, and setup for a lot more then 400/300 lb springs... and they ARE coilovers as well...

The stock Escort valving as designed by Porsche/Bilstein is over 600 pounds. You can have Bilstein revalve relatively easily.
The Escort cup setup is THE cup setup. The Bilstein IMSA Firehawk is also a race shock, but slightly softer.
I have the Firehawk on my ITS car and Escort on my turbo. I had Canadian cup Konis on my turbo before (double adjustable threaded sleeve).
Firehawk rear - conventionl non-threaded body shock
Firehawk front - threaded body shock
Cup front - threaded body shock
Cup rear - threaded body shock (rubber eyes)

Bilstein's body are threaded. Konis are slip on sleeve threaded.
NONE of the Bilstein 944 competition shocks are adjustable.
Anyone who wants non-speculation first hand experience with these suspensions, shoot me a pm.

 

I do, but i'm doubting your going to be around anytime soon... with the car... Where did you get the escort cup setup, what springs and T bars and sways etc are you running it with, and do you have photos?

so what is this then?

I'm trying to understand exactly, since i have a future purchase at stake here.

I agree with turbocup, the Cup setup is only for race and really too stiff for a road use !

I have the 968 M030 setup (at 90% stiff) on my 951 and the Bilstein Cup suspension on my Turbo Cup, and the Cup suspension is way over the 968 M030... for a race use !
For street use, the Cup suspension is too stiff and the car is jumping everytime. A 951 or 968 M030 setup is better for this use.

Don't forget the aim of the suspension is not too be as stiff as possible but to keep the 4 wheels on the road and help to use the power. Too soft on the track is bad but too stiff on the street is also bad !

 

Im setting up the car to prefferably see almost as much track time as it does street, therefore, track has a priority for me.

Listen, - I am telling you what is for sale now. The "polish" package is a new nickel plating that Bilstein has just switched to. Do you own any of these suspensions?? I have owned ALL of them, kido. Shoot me a pm, Turbocup, so I can tell you what you are talking about.

 

special tool,
from your experience, which setup is best for track only use?

Thanks.

 

I have to say, they are both good. We are running 1:04 at Lime Rock in a LEGAL
(as in passes SCCA tech LEGAL) ITS car with just Firehawk. I actually think the Firehawk is a little soft with stock t-bars in the rear, but it is illegal for me to modify number and type of spring, so I can only change t-bar diameter.
In a more open class, I would use cup, but they are stiff for the street unless you are a weirdo like me.

 

So does anyone know if Porsche offered for street cars an option for rear
coilover shocks and the progressive rate 190-400# springs up front?

My reasonong for this is that if it was offered as a factory option then I might
be able to justify to my local SCCA SOlO2 club the rear coilovers and heavier
springs and stay in a stock class.

The M030 Koni setup works well for street but I think the springs might be to soft for what I do with the car.

I guess I'm reaching hear.

I heard that Excelence has an in depth look at the 951Cup Cars this month.
May this will answer some questions.
