Running SPG springs and 16" Super Aero's w/205/55's. Anyone have a definitive answer on preferred settings for enthusiast non-racing back road driving? Different front-back? Have a similar set-up on two c900t's so lots of work to remove and re-set them. Thanks!

Well a softer setting has more positive rebound damping, a firmer setting less.

generally softer on the front and firmer on the rear will provide good road holding for a front wheel drive car.

in reality the koni adjustability always used to be there to compensate for wear - the koni manuals used to say only increase the firmness when damping performance begins to decrease due to age/wear etc.

I think somewhere they say not to go to the hardest setting when new / newish as its hard on the shock absorber.

Hey Thanks! for the reply. Had about given up on anyone responding.
FWIW, I started at setting #1 on both front and rear. After a bit of driving, bumped up the rears to setting #2 (of 3) and the fronts to #2 (of 4) on the SPG. On the '93 c900t, #1 on the front and #2 on the rear. Can't tell much difference but I like the #2/#2 set-up better. Reminder: both have SPG springs, SAS spacers in rear and 16" Aero wheels.

I think when I installed mine I left them both full soft and was so happy with the ride and performance and behavior over bumps that I never bothered to pull them back out.

Or maybe they are both in the middle. I never felt the need to mess with it.

I had a 9000 Aero with Konis and the rears were set to one notch firmer then the front. I never touched them again because the ride was so good. It made the 9000 feel more like a 900.

I have a set of Konis for my 99 hot rod project. 99 fronts, 900 rears. Thats a way away though.
