to much for me to understand, what is an Ideal curve?
The one thing every camp can agree on however, is damping on the rebound side.None of us want to over-damp a spring in rebound damping, as this leads to "jacking down" onto the bumpstops and will cause an overly harsh ride and even worse handling.Well actually... I say everyone, but in truth the Autocross community is one of the worst for running shock absorbers with entirely too much rebound damping (and often compression damping as well).You mostly see this in stock classes, where the rules prevent you from changing springs.Basically they crank up the shock absorbers as high as possible, giving up all-out grip in favor of transitional response and feel.The one time the average stock class autocross guru will go against this conventional wisdom of the herd is in the wet, where the higher grip of the more relaxed damper settings will payoff much better than the "death grip ultra responsive" over-damped settings.
My personal opinion on shock absorber damping:I think it depends ENTIRELY on your use of the car and the condition of the roads, race track, or autocross course you are going to drive on.There just isn't one damper setting that will work for EVERY condition out there; this is the reason we are seeing more and more "magnetic ride selection" options being made available for various sports cars from various manufacturers all over the world.It's the reason the GT-R, Corvette ZR1, and Porsche 911 Turbo just to name 3 examples have multiple shock absorber damping profiles to fit varying conditions.The super soft under-damped shock absorbers found on the 06-08 NC sport models will not be optimal for autocross or track driving, and may not even be suitable for someone seeking a truly sporty handling vehicle.And the inverse is also true in that a autocross or track driving setup will not be optimal for the 06-08 NC owner seeking a comfortable cruising car.What's best for absolute grip in the dry on 225/50/15 R-comp tires on a smooth as glass autocross course will never work properly on the same car sporting 195/50/15 street tires on a bumpy road in the rain.Shock absorber damping is like anything in life, it's a compromise.The trick is figuring out the priorities, and spending your money accordingly knowing full well the pay-offs and compromises involved in your decision.
And the last item of contention on my last post: You CAN have a car that rides great, handles great, and has enormous amounts of grip. Hard to believe I know, but with the right combination of spring rate and bounce frequencies and proper bump/rebound damping ratios, it can be done.
