So, it sounds like on tight tracks, you need less camber so you can get more bite off the corners & use more brake. And on bigger tracks w/ more momentum ,you can use more camber. I really enjoy these kinds of write-ups, awesome!
I agree with both, it just depends on the overall dynamics of the vehicle. Chassis tuning / design is always a compromise, there is no perfect set-up and driving style is an important part of the set-up considerations.I believe it's just the opposite. On tight couses more camber is OK. On long fast courses reduced camber because you want lots of tire on the pavement for straight line stability. It's better to tune with spring and sway bar stiffness than relying on camber alone.
Chassis set-up is definitely a black art, and for most amatuer racers, the most significant points to focus on are......
Does the car remain stable under heavy braking?
Can you trail brake with confidence to improve weight transfer and induce vehicle rotation?
Can you use the entire track effectively, IE, turn in, hit apex, track out without making constant corrections?
You should be able to turn in to a set sterring angle, and hit your apex and track out with minimal steering correction if any at all.
IS the car balanced under steady state cornering? IE no bobbing, pitching, rolling etc
Is the car stable on corner exit/under acceleration?
Unless you are running with the pros' looking for a 10th of a second per lap, having an overall balanced set up is all that's needed to have a competitive vehicle, the rest is just driver skills and consistency. (brass balls help too!)
When trying to resolve handling issues and troubleshoot what needs to be corrected, ( sometimes it's just the driver, not the car) Carroll Smith's "Engineer In Your Pocket" is going to get you sorted out 95% of the time.
If you are serious about getting your car set up for track events, this will be a big help. If you need more in depth technical reference for chassis dynamics I recommend his book, "Tune To Win".
Remember there is no PERFECT set-up, however driving style and set-up must match.
My sway bars are somewhat stiff, (the largest made for the focus) but springs are a touch on the soft side since I like to tag the curbing alot. You always have to be looking far ahead of where you are, focusing on where you are going to be 5 seconds from now. Tagging the curbs is my way of knowing where the edge of the track is, without drawing my visual focus to the front of my car. When i'm really dialed in and driving my best, I can run curb to curb with confidence on all but the most difficult corners.
