I would prefer to stay at the softer adjustment and creep up as if you start out to firm with the damping it may be the shocks doing all the work and not the springs.

In any case, there should be experienced people there who can point you in the right direction as to how to go.

If not already done, get a good wheel alignment before the track day, this will be of more benefit than playing with the damper adjustment, which in your case jackmack has already been done.

I will be there so I can point you in the right direction for getting set up initially and let you learn the track and the car if you want.

Correct, on initial turn in.

Unfortunately shocks are not that simple, being the function of velocity rather than displacement such as springs, changing the setting can have all sorts of results at various points through a turn. Throw in separately adjustable bump and rebound and it makes the situation much more complex.

One tip I was told years ago which probably applies more to mid corner to exit is the the end that is loose, make it firmer, or make the other end softer. this like most shock tuning tips is a fairly general one and not always the right one, but I have found that this has helped me a lot. Typically I find that you adjust it in small increments and it gets better and better then it sort of drops off a cliff where it gets much worse, I then go back a touch and it is pretty good.

Cheers,

Tim

Its definately correct on initial turn in, and not definately correct all the way through the corner.

Looks perfect for a FWD car.
