Upgrading Suspension on my Turbo - Need Help

Porshapwr · 01-26-2002, 07:48 AM

Hi Everyone,

I've spoken to a few people on these boards about upgrading the suspension on my 88 951 (Non S) and have heard a few opinions.

Well I've got the money together and really need some advice on what parts EXACTLY people have used.

Keep in mind that I like the suspension VERY tight and the car being stiff doesn't bother me in the least. I originally considered doing Bilstein Coilovers but I feel that they really aren't worth it for a street car.

Thanks!

PH front springs, progressive.
28 mm front sway bar fixed.
Weltmeister adjustable sway bar in rear.
Koni adjustable shocks front/rear.
Monoball at top of struts front.
1.5 degrees negative camber front.
Don't know what rear is - dealer did it 1/2 degree?
Ducted brakes front with PF 93 pads (corrosive pads).
Frozen rotors.
Weltmeister strut tower brace.

My opinion is that this gives a reasonable street ride yet can be used on the track. I'm not M. Schumacher so it is good enough for me.

What exactly do you want out of your car?

There are quite a few different suspension solutions out there.

Koni yellows with stock or aftermarket springs

Bilstein Sport with stock or aftermarket springs

Bilstein Soft Road Race (coilover front), need at least Turbo S front springs and 25 mm or larger torsion bars. This combo has great ride quality.

Bilstein Soft Road Race (coilover front) 300 lb/in 2.5" ID 10" long, may require custom spring hardware. 28 mm rear torsion bars. Turbo S upper strut mounts. A little less ride quality a little more handling and response.

Weltmeister adjustable sway bars front and rear no matter what.

FYI the car doesn't have to feel stiff, it has to be right. Stiff is full coilover setup with the hard set of Bilstein Road race shocks, 400 lbs front springs at least. And even then it isn't bad on street rubber. Solid bushings make things feel realy stiff as well.

Lawrence,
Try moving up to PFC 97 from 93. Last longer and has great feel and improved modulation especially release characteristics. Really good for trailbraking.

Pilot, I'm due for some new pads so I'll give them a try. Can I use the old 93's on the rear with the 97's up front or must I use all 97's?

If you're basically using it on the street, go with Koni's. I found a used set and being adjustible, are the perfect setup. If its just a track set-up you're looking for. Go to Huntley Racing for coilovers. They can be had for $2000 all around and offer a wide range of spring options. I also agree with others that the Weltmeister adj. sways are the way to go.

Lawrence,
You will be fine with the 93s on the rear until they wear out and you can replace them with 97s.
