I had to hack my Mazda wing at the reedy race and that made the car terrible to drive. The rear end wasn't the same anymore. Going by roar rules the caddy that Mo has been running is legal. That's the body that I have been using and I really like it. We'll see how the tech is once we get down to the track.

The ROAR Rule book does not specify a wings max. or min. dimension for touring cars in their diagram on page 67 of the rule book. It only shows that the roof must be at least 117mm high and on page 47 (Touring car class specifications) it states that the wing must not extend more than .4" off the rear of the body and may not extend above the roof height.

My wing ended up super small at nats. They were measuring the "wing chord". It had to be 40mm from the top rear corner of the side dam to the lower front corner of the side dam. Atleast thats how they measured mine. Then the wing could also only be 20mm tall. I don't think anyone's wing stuck above their roof height once they cut their wings down to that size . After the wing was small enough it looked wierd sitting on the back of the car.

The same thing happened to a lot of guys at the 2003 asphalt nats in NC. R.O.A.R. really needs to build a tech stand.

Ok guys, here at the track with foams and having a problem. The car is hopping the rear end a bit from the middle out, costing me some exit speed. I am using 80wt front, 60 wt 60 wt rear oil with ae copper fronts and 20.91lb rear springs. I am thinking about giving the car more negative camber and possibly dropping the rear spring down 1 rate. any ideas?

With Foams i found the rear to hop when it had too much rear grip, make sure you run enough camber so that the tires cone slighly inwards, also try lengthening the camber link i found this to free up the car on foams. I also found that going to the second outer hole on the rear arm kept the car much flatter and more stable through fast changes of direction.

It might also be an issue of too heavy oil combined with too light a spring. I am finding the car likes light oil (35wt) with firmer springs with foam on asphalt.

Gary-- I have been using 30lb front springs w/60wt and 3 hole pistons. 28lb w/50wt in the back. The car just seems to work better when its stiffer.

Your oil is WAY to heavy for the springs being used (heavy spring is ok, but not oil) You should never have to go more than 50 or 60wt in the front! Here is a quick story....One day some guy told Paul Lemieux his oil was to light for carpet/foam. So Paul poured out all the oil from his shocks and then layed down some of his fastest laps of the day

E-mail me for a setup paul@schumacherusa.net

Gary,
I have experienced the "hop" you are having trouble with. First, take out the riser plate. I have my mounts 1 mm spaced up from chassis. Then no spacer on the ball stud, for the alloy rear hub inner hole, upper center hole on tower for camber link. -2 deg camber, 0 toe in(you need the alloy arm mounts to reach this) or .5 with the plastic should still be ok. Unlike what Paul Wynn says, I am going to try a heavier setup for a techical track, and will keep you posted. Our cars are getting faster every night we run them. My sponsor and I run Mi2's and try a little different stuff and compare. I started with a hop, my hop has gone, now I am concentrating on going faster.
