Hi Guys
I have been following this thread because of two things. The first having 
been involved in FJ's a long time ago in the UK and second because I actually 
like the challenge of setting up suspension systems on open wheeled cars and 
trying to get it better than the next guy. 

OK lets take the point that the new generation are going for heavier and 
heavier spring rates. They are in a different game!  They use better rubber 
than we can and distance between the underside of the car and the track 
surface is a critical factor in the way they want the car to work. This is 
not just for the F1 boys either, the lower ranks are also involved with this 
stuff.

If you fit 1000# springs to you car you had better get some good reaction 
times because, IMHO you are going to need them. They car will slide with 
great ease!
The roll can be controlled with the right spring settings and the right roll 
bar. From memory we used 350-450# depending upon the circuit and track 
conditions. That to was regarded as overkill by some! But it seemed to work 
for us. 

Just putting in my . 02 cents worth.
