Regarding the KONI 2812's bump and rebound settings -
I assume the settings are (-) softest, (+) stiffest. 8 settings B and R.

I set my bump at 6, rebound at 4 FRONT. For the REARS, bump at 4, rebound at 3.

My reasoning is that I wanted to keep the rear at a softer setting vs. the front to compensate for the "twitchy" rear characteristic of our car. I put more rebound in the front since more rebound is supposed to enhance understeer. Our cars oversteer at speed. I tried to tone this tendency down a bit by running more rebound.

Many questions, I have.
* What do others have their bump/rebound settings at? Mainly interested in track settings.
* Does anyone vary their settings front to rear?
* Can anyone explain the specific handling effects of increasing/decreasing bump and rebound?

* Anybody have a good base track setting to progress from by making incremental adjustments at the track?

Thanks in advance.

The late great pmum recommended:

3/4" lowered - any more and shocks pack up on bumpy tracks
bump on 3 all around
rebound on 2 up front, and 4 in the rear.
(I might have the bump/rebound reversed, I'll have to check)

The lowering affects the values. Compressing the springs makes the car feel much different, and only after I lowered the car 3/4" did those settings really come into their own.

Also, add a track alignment to that. I'm running -1.9 camber up front and -1.5 in the rear at the moment. Car is nearly 50/50 balanced. Its like a new car compared to the stock align/ride height/shock settings.

I haven't played with the settings much. If anything, I might soften it a bit to try to let the weight transfer easier, then slowly go to firmer.
