Depends on how sharp you want your car Phil. Steve at Jazz has a lot of 993 cup experience. Paul would probably have a set up also. Going to the event in April?

Yes going to the April event (my 8th or 9th edition, have now lost count--still remember when it was costing 400 euros for the 3-day package [
]). My car not in the UK so parameters would need to be relayed to my mechanic. I'd like a "comfortable/stable set up", something not too nervous, as I will be driving quite a lot in all sorts of conditions (not just climatic but some people can be unpredictable).
I loved the set-up when I drove the RSR: http://www.youtube.com/watch?v=SMbAN6nDuQ0
This was on slicks, full stiff roll bar at the front; mid-range at the rear (cambers front and rear were quite high, never knew exact values).
I now have a 993 CUP, on Michelin Cups (to be replaced by slicks for the April event) and I have had the roll bars adjusted in the same way as the RSR (still not idea about camber settings). My understanding is that full-stiff and the front and mid-range at the rear is the set-up of choice (transition from turn-in understeer to neutral on full throttle exit) for the long fast curves.
Awaiting any input on set-ups that people might have.

Phil, I'd take it to a race team that have experience wherever the car is and ask them to do it for you. 911's are incredibly sensitive to geo and damping changes. Just one click on a damper can make a difference. with a 993 cup having so few roll bar settings, any adjusment will be huge to the balance of the car as will camber changes and all that will depend on your ultimate tyre choice. If you guess it, you will probably end up with an evil handling car

I thought i gave you the settings,more than good enough for track days.
When i run the car i had who i would consider one of the very best in the game set the car up initially,sadly now retired from the game. .
Also mich cups are not much slower than slicks,if you want some value out of your tyres and lap times dont count,go for dunlop slicks,you can wear them out,unlike the mich slicks..Or even the dunlop track day tyre is very good,run them on my rs for years.Less camber needed because they are softer,and will overheat if you dont.The cup is nothing like as sensitive as a fully rose jointed rsr,infact when you are on 100% the car squirms from flex.
You will find that you lose speed/time from the front end and not the rear,lots of grip in the rear.

Paul, thanks, set-up definitely worked very well.
Tried it first with my initial "typical" Spa roll bar set-up of one off full hard at the front and mid at the rear, but the car understeered like a pig--"warmed up" the front tyres to 3.5 bars!!!
Went straight to one off full hard at the front and full stiff at the rear and after re-inflating the front tyres, the car was beautifully balanced, with very nice turn in and nice balance on power. The camber was just right and I could actually see the "former camber angle tyre wear" higher up on the side wall, so more camber was definitely required. Could easily stay on power until the compression at Eau Rouge with excellent turn in for Raidillon. Managed a 2.44s on not fresh Michelin Cup, so not bad set up at all!
Having significant ballast on the right seat sometimes upset lines (quite significantly actually). Understeered three times at double-left and had to take the long way around in the run-off area.
Thanks again for set-up, which was a revelation.
Saying all this, seeing a GT3 Cup S flowing around the track about 20s faster than the old banger was another revelation! Time to move on?

Good to hear the set up works,with fresh tyres its normally spot on for spa.
Extra camber is great in the dry,problem then is if its wet , you then have less grip!
Cup cars on pirelli slicks, used to run 4 plus neg on the front,and 3 to 3.5 rears.And of course a army of people to re set if wet.[]
Time to move on! well its what you are setting out to achieve, fast lap times on a track day or sheer fun.
The grip in the later cars is awesome but very expensive to run .
Best fun i had on a track last year was in my 74rsr at spa,8,000rpm ,open pipes and 335 tires on the rear.

I think Paul is spot on with the fun bit; buy a single sestet for max speed
an old formula ford will do it but a nicely set up 911 that moves around is a challenge and great fun
i do wonder if the later cars for all their undeniable pace loose in fun what they gain in pace and do seem to cost a big leg up in bills with all that extra flab
I was reflecting how although slower on road tyres the rs does have more feel than toyos?

Yes, a very nice set-up...
Yes, I can relate to your 335 rear tyres fun when I had 305 on the rear with the 964 RSR. It gives the notion of driving 911s with all the weight transferred on the rear a new meaning!
Now, it did not seem to me that the 996/7 GT3 Cup brigade was missing out on any fun.
I certainly want to try one out to see what it feels like.

deff go for one,996 or 997 is great on track,just even more expensive to have fun.
The r and rsr versions are even better,some could be a wise buy if you can find the right cars.
