I'm starting to become interested in shocks, and I have a couple of questions perhaps some of you might be able to answer.
Question 1
Say our car is in "mythical steady state cornering" at 1.3 g's...
Lets say the shock travel from rest is 10 mm at this point....
Where would you ideally like to see the transition from low-speed to high-speed response on a dyno plot?
10 mm.s^-1 ?
20 mm.s^-1 ?
(see point "x" in graph attached)
Question 2
Are you looking for your (transient roll stiffness?) "turn-in" (with a smooth driver) to be dominated by the "low-speed response" of the shock?
Question 3
If "yes" to question 2, is it ideal to have an equal "low speed response" in both rebound and compression?
Question 4
Or are you wanting the "high-speed response" to be dominate turn-in, and since rebound has typically a greater damping rate, you end up concentrating on rebound settings in transient lateral g's?
Question 3
If you are primarily tuning the transient lateral g's using rebound settings, does this mean the car will dive in transient lateral g's? (and get less roll on turn in / more roll on corner exit?)
Thx in advance to responses to this fairly confused questioning
