Does anyone have experience with recommended setting son Thw QA1 shocks for setting front and rear for AutoX, drags or daily driving?
Ant experience is helpful.

IF the car has stock springs and swaybars, you should probably stiffen the rears up to like 9 if not 10 (maybe more, but work your way up) and then bring the fronts up until you're comfortable with how the car can be a band aid for bars that aren't setup how you want them to be in mostly transient situations.

For Drag racing I am using 0 on the fronts and on the rear I used 8R and 9L. We were playing with the settings earlier this week and when everything else failed to produce a spin free launch we set the rears at 12 and it finally hooked.

For road racing I put them at pretty much the highest settings on all 4 corners.

WHEN I had swaybars (stock front, HO rear) & stock springs, I had them at 5 all around. Seems to be about stock DeCarbons. When I removed all the swaybars (stock springs), I put them up to 7 and its a lil stiffer but I don't get as much body roll staying with 5. It's a good comprise. For drag racing, 0 for the front and about 9 for the rear. Before I moved, I was playing with settings at the local track. 9 clicks with 15# in the pass side airbag with IC brackets has netted me 1.7x 60 foots on a 'ok' prepped track. Previous BEST was 1.87 with an average of low 1.9's.

Thanks this gives me a good starting place.
I guess I should have added that I have a wagon.
Eibach springs front and rear.
Hotchkis Bars front and rear.
Hotchkis rear trailing Arms.
285/40-17 tires
Air lift bags in rear springs with Individual fill.
I was running the stiff Bilsteins, but I'm converting to the QA1
Did the fronts today.
