Thanks for the help Trent !!
I ended up going lighter on the spring as the carpet was not ozite, and although it was a great surface to run on, there was a lot of fuzz from it, and loads of wheelspin, so I went for a smoother feel.
The deal with this is that they add together every single lap you do all weekend long, so at the end of it all I had 239 laps total, I won the event by 10 seconds after all that running !!
Great weekend, thanks again for the help, another title for T-Bang !!
