911's are renowned if not infamous for having a lot of weight hanging out at the back, unlike their thoroughbred competitors.  It's absolutely essential therefore that you make sure your 911 is corner weighted and balanced properly - especially so if your intending on taking your 911 to the limit on a track. 

Geometry setting is a job for professional to get it right.  It takes time and money to do it properly. If you adjust the corner weights and balance it will effect geomtry. Corner weight and balancing should be done BEFORE you play around with the cars geometry.

Its also important to do the corner weighting with the driver on board
The car is going nowhere without a driver, so it is pointless to do it without the driver
All the 911s I have corner weghted with the driver on board run super heavy on the driver's side rear corner
This effectively means you are sitting on a 3 legged chair!!

+1 Carlo.  I've ended up being the balast for some peoples 911'a while the corner weights are set.

If you guys are interested, I would be happy to post "Set Up" guidelines that I did for my guys at the shop, just gives general procedures for preparing the car for set up.

You could also tell me to stop poking my nose in!!

Hi Nick - please do post your guidelines.  Much appreciated.  Perhaps put it in the 'Reference Library' section.....Much appreciated.
