I've got to find out how to adjust these as there is no mention of procedure in my manual. I am trying to correct a handling problem I'm having, the rear end of my car just won't stick as well as I think it should. Michelin Pilot Sports at the recommended 36psi. Problem is very noticeable in low and medium speed corners. I assume firming up the rear shocks might help. Looking for any advice... Allan

Strangely enough, stiffening up the rear will make the front end stick better and stiffening up the front will make the rear stick better. If you have the Koni adjustable shocks & struts which should have come with M030 option, the rears must be removed from the car, the bump sopt rubber pulled out from the dust cover and the shock collapsed fully to engage the adjusting lug then turn clockwise to firm up and counter-clockwise to soften the shock. You will notice the difference by the amount of pressure required to collapse the shock and the speed of return to normal position. The front struts are adjustable with a removable, knob which is placed on the top of the strut and turned to firm or soften the struts action. Good luck, bob blackwell.
before you go adjusting shocks to try to resolve a handling issue, realize that shocks are supposed to do one thing and one thing only - they dampen springs - their entire purpose is to control the bounce of the spring, and the natural frequency of the suspension - they are not to stiffen up the suspension - they are not to correct oversteer or understeer
far too many people set their shocks and struts way too stiff, hoping that stiffer is better - it isn't always the case - the settings must match the springs - it really fakes you out, and you think you are going faster, but if you looked at entry and exit speeds, you would find this not to be the case - stiff shocks on too soft of a spring actually scrubs speed
i don't know what the setup is on your car, but if you have an oversteer problem, i would first look at spring rate balance front to rear - then, swaybar settings - then i would check your alignment geometry
it is very possible that you have too much negative camber - i see this all the time - people set up a car with a lot of negative camber, thinking that this will improve cornering - in reality, it can easily mean less total contact patch in a corner, and ugly weight loading of the outside tire, resulting in both understeer and oversteer
while too stiff of a setting on the rear can lead to oversteer, it will always show up in a very jouncy rear end, especially with gas shocks like konis, and their inherant preload charge - it will cause the car to dance around on bumps and such - if this is not the case on your car, your problem is definitely elsewhere
everything works together in concert - i would first establish that everything is right before doing the fine tuning of shocks - if you don't, you could easily make things worse, and a lot less predictable
