Cup shocks for a GT3 and revalving..?
A friend of mine is going to change renew his cup shocks.
1.- Can they be directly fitted in my 2003 GT3 ? and,
2.-. Can I send them somewhere do have them revalved ? and,
3.- Wil they behave " as new" after the revalving ? and,
4.- Is it worth doing all this ?
Thanks in advance for all your answers..

Hi
Have you driven on the Circuit de Cataluna? It is very very smooth. The standard Cup shocks are designed with that kind of surface in mind. From 2003 (I think) onwards, the Cup shocks are adjestable. However, they are not the most sophisticated, in terms of their adjustability, as they do not need to be as they are used on a very liumited number of very well maintained race tracks.
The Cup cars which run at the Nürburgring all have their shocks, and springs, changed.
As far as I can tell, you drive on the street, smooth tracks and bumpier tracks. Some of your street driving will be on very poor roads.
If I were you, I would find a company that specialises in suspension systems and work out a plan as to how to get from what you have now to an ageed 'perfect' system and set up.
The very best Öhlins systems are sufficiently adjustable that you can use them on street and track. In your shoes I would look to having the shocks set up for double digressive valving.
It may pay for you to swap out some GT3 parts and substitute GT3RS parts as these have sliughtly superior geometry and are a better platform to build an 'ultimate' system upon.

Thanks Nordschleife... The fact is that I ONLY drive my car on spanish tracks which are usually "reasonably" smooth. As far as I know, nothing comparable to the Nürburgring. The only streets that I have used this year is the one that gets me to the Jarama track and back home ( 80km) all over. I take my car by truck to the rest of the tracks.. I am now considering a "serious" rollover cage which will legally exclude my car from the streets.

BUT - if you are modifying your car so that it is no longer legal on the street, the economics all change. You might be better off getting a GT3 Cup for the track and a SEAT TDI for the street...
I was looking forward to you driving me over the Sierra Nevadas early one morning, before anybody gets up....

2. Yes, if they are Bilsteins you can send them back to them for revalving.
3. They can set them to whatever car weight and spring rate you specify.
4. That is the big question. After going through the whole thing I would now recommend using ajustable shocks.

Nordschleife,
Thanks again.
In any case, for the moment I plan to keep my GT3: nor a Seat ( I already have a....Mini), nor a Cup ( I am really affraid of the maintenance costs involved ..). My thoughts on changing the shocks came after a conversation with my friend - the one who is gong to renew his Cup suspension and discard his present shocks (!) - and thinñing that: 1) the slicks will surely benefit from a stiffer setting and 2) that the suspension of my GT3 has 24.000 km out of which 12.000 km ( the time the car has been of my property ) have been made, solely , on tracks adn - probably - the shocks are not keeping anymore their original properties..
The cage is abecoming a ...must. This year, two of my track mates have rolled over on different track days . One of them quite seriously on a 110 kn corner, after a slide that hitted a protection that finally sent him flying. Something that could happen to anyone. Fortunately enough, both were driving cars fully prepared for racing ( cage, fire extinguishers systems, etc..). I wonder how my GT3 Porsche tequipment bar would behave in such a circumstance...

Mike K,
Thanks. I understand , after your comment and Nordschleife's advise, that the adjustable schocks ( Ohlins,Motons,..) should be the best option. In this case, it will depend on the revalving cost from BIlstein... If it's cheap enough, I will probably opt - in this stage - for the Cup shocks ( as they will come , nearly, as a free option..)

I see a lot of GT3's with Öhlins and looking at the results, it's superior to the Cup Car suspension, even on smooth tracks it seems so. Crucial is that you get them setup correctly, it can be a PITA.

Per shock.
+1 for the the DA's. The DA's (double adjustables) will bolt on with no modification to the vehicle, only additional ancillaries. You will need the top mounts with their corresponding bushings. We have those on the shelf if you need to source.
You'll also need a spring set with helpers or tenders. Add about $700-1000 for a complete set with perches, hats, couplers, mains and helpers. For tenders add an extra $300. Eibach is the brand we carry and recommend. They stay accurate longer and of all the springs we've run are the least likely to "coil bind". I recommend you run a 2.25" inch spring combination.
To make the most of the doubles, you can also upgrade to the Cup Car or RSR control arms. Of course as we all know, the GT3 possible upgrades list is a long long list with all kinds of financials involved.

Austin,
Sorry to keep you busy..
Then , the figures in order to rebuilt and install the Sachs in my car will be (?):
Revalving 4x 300 = 1200
Perches= 1000
Tenders= 300
TOTAL 2.500 ?
