914-6 GT fast road/track suspension settings Options

[amallagh]

Hi,
I'm just about to have the suspension set up on my 914-6 GT project and wanted to see if anyone had any advice. I have never done this before (my first 914) and was looking for a fast road/track set up. I think the range of settings people seem to talk about on Toe and Caster is fairly small but camber settings vary wildly depending on what people want to do and type of tyres.
I know the theory about track set up and measuring temperatures across the width of the tyre but this car will spend more time on the road than track (albeit I could be called a spirited road driver!), and tracktime ain't cheap !
Suspension components are :-
FRONT -
Sway-a-way 22mm hollow torsion bars
Weltmeister 22mm sway bar
Bilstein shocks
Weltmeister camber plates
Fuchs 7X15s with Goodyear Eagle GSD3 205/50s
REAR -
Weltmeister 140lb springs or 180lb springs available - need to decide which ones are best to use ?
Weltmeister 16mm sway bar
Koni adjustable shocks (yellow)
Stable Energies rear strut tower camber brace.
Weltmeister chassis and suspension arm stiffening kits
Fuchs 8X15s with Goodyear Eagle GSD3 225/50s
Tyres will be

This is what I was planning to do based on some previous indications:-
FRONT -
Toe in(each wheel)- 10'
Camber- 1 degree negative
Caster- 6 degrees
REAR -
Toe in(each wheel)- 15'
Camber- 1.5 degrees negative

#############################################
I think these are the factory settings -
FRONT -
Toe in(combined) 20' +/-10'
Camber- 0 degrees +/-20'
Caster- 6 degrees +/-30'
REAR -
Toe in(each wheel) - 0 degrees +15'
Camber- 30' +/-20' negative
##############################################

I would welcome any advice or opinions. If anyone has any advice on initial settings for the rear Koni shocks then that would be a real bonus. All advice gratefully received and without prejudice.

Auto-x "Autocross is a form of motorsports that emphasizes safe, low-cost competition and active participation. An autocross is a timed competition where drivers navigate one at a time through a temporary course marked by traffic cones, rather than racing on a track with multiple other cars, as in road racing or oval racing. Autocross tends to place more emphasis on car handling and driver skill than on sheer horsepower, and events typically have many classes which allow almost any vehicle, from economy sedans to purpose-built vehicles, to compete. Speeds are slower in absolute terms when compared to other forms of motorsports, usually not exceeding highway speeds, but the activity level (measured in discrete turns per minute) can be higher than even Formula One due to the large number of elements packed into each course. Autocross courses are typically 40 to 70 seconds in length. In addition to being a national-level motorsport in its own right, autocrossing is a good way to learn skills that transfer to road racing, as drivers learn vehicle control and club ethics.
Autocross events are usually held in large paved areas like parking lots or airfields. Typically, new courses are created for each event so drivers must learn a new course each time they compete. Prior to driving, a competitor will walk the course, taking mental notes, and developing a strategy to be refined upon subsequent runs. National organizations such as the Sports Car Club of America (SCCA) and National Auto Sport Association (NASA) sponsor autocross events throughout the United States, and many areas have independent autocross clubs. Automobile manufacturers and their associated clubs (e.g. the BMW Car Club of America) sometimes hold marque autocross events."

Unlike Autcross in your part of the world which is akin to a rally stage over here.

"In the United Kingdom, autocrosses are typically held on a grass or stubble surface. In fact the attraction is the challenge of driving quickly on challenging and difficult surfaces. Cars compete individually against the clock, although more than one car may start at the same time if the circuit is long enough and wide enough. Because the course is usually bumpy and there is a risk of contact with other cars, most competitors use specially prepared cars (which vary from very inexpensive to specially engineered racers) brought on trailers. Events are usually held on a region-wide basis, with the RACMSA (Royal Automobile Club Motor Sports Association, now often called MSA)) overseeing rules and regulations."
