Thanks guys for the "all the best" for the NSR race, it will be a blast.
Thank You guys for letting us run these cars.
Allan, is it OK for me to repair the J car, the windows have come loose and are floating, I'd like to glue them back in place if the rules allow this.
It is not having any real effect on the car as yet but it may do if it comes totally loose and flops around.
The track was washed clean before we qualified them, I split the cars into two groups, rubber tired cars in one group and urethane and silicone tired cars in the other.
We ran the rubber tired cars first at random order, washed the track again and then ran the rest of the cars also in a random order.
This way no car had a dirty or dusty track to contend with, ie the rubber tires didn't have to deal with the dust from the urethanes or the silicones pulling up the rubber from the track.
As Mike said, the rubber tires do run better on this surface, they always have.
My theory as to why is they are softer than the urethane tires and when cornering they hold better because of it.
That is just a theory as we normally use soft rubber tires form most of the cars we race.
We do have a class of old school Trans Am cars where most cars do use urethane tires but the quickest we have them running is around 5.0 seconds using 16k to 18k motors.
We mainly use urethane tires for these cars to keep them consistent over each lane and during the race.
We will get to race day as soon as we can after we get back from 'the big one' next weekend.
There were some really great running cars in this bunch,
#23 Porsche is a great runner, awesome handling car with that very cool custom chassis, hats off to the builder of that one.
#70 stands out also stands out for being the best car to drive using urethanes.
Other cars have some simple issues hindering performance, things like tires coming loose off the rim while cornering, front and or rear tires not running true and bodies rubbing on tires as it tilts during cornering. These simple things can and do have a huge effect on how the car runs on the track.
Thanks again Guys, I'll keep ya posted when race day is on - Dave.
