Can you post a list of things to try?
You can look at my first post, as that has some things in it. Quite a bit is based on traction level, like I can't say "always run a 12lb spring", but I'll try to point some stuff out I think is important. I hope some guys who have had success will post what they think is important too.
*Relatively soft car- I think the tire compound being what it is, basically from 1996 (lol), you need more mechanical traction than current TC tires. So springs at the very soft range are appropriate. This lets the tire work w/o overloading them.
I really only was able to figure this out last week, since if the tires got hot, they wrapped with fuzz from the track (too sticky). I had seen shades of this in 8 minute main races where the car would get funny handling part way thru the race if you overdrove it.
If you calmed down, it would come back. My car was too stiff, especially in front. Softer=faster, and more consistent for 8 minutes.
*Higher roll centers- I think this is dependent on the car, but if you follow with softer springs, the car will roll more. A higher hinge pin mount will take some of this out of the car. I am now starting to think the front roll center should be equal to or higher than the rear. My car rolled across the nose a lot in the main, and was loosing speed due to this.
Also, Mike Haynes (Dominator of the Gate)has the hinge pins higher in the front than the rear in his setup. Jimmy S (g12314), who was very fast last week, also has higher front pins, and my buddy Kevin K did too. Notice the trend?
I think it works well with the softer springs since it lets the car rotate off the rear end more. Probably helps the front tires from getting roasted too.
*Less Rear Camber- I'm not as sure about this one, but I think you may as well use all of that big honkin' tire. I know that my car didn't get loose at 1* of camber like it did before. Still, not 100% on this...
*Stuff that may or may not be so great....-
Sway bars-I put them on my car since it rolled a lot. I wound up removing the rear bar for the main, but I think it was a mistake. It actually helped control some of the front end roll. The rear of your car actually influences things a lot, especially rotation. The good thing about swaybars is it can keep your car flatter in the corner, but let the weight get on the nose or back to the rear dependent on throttle. Some people don't like them...
Long camber links-I wound up here more by chance than anything. The front needed it, but the rear was unchanged from when I was looking for more rear traction when my car was picking up fuzz. Longer camber links aren't as reactive.
Droop-My car seemed better when I had a lot of rear droop. Not sure why. Normally I wouldn't run a lot of droop, and the track conditions were a bit odd, so I will have to review this.
Hope this helps
