QA1 adjustable shock settings.

I am wondering what your preferred settings are for the strip AND the street. I am getting ready for drag racing this year, and have always just left them at 6 all around for street use. Consensus seems to be softer in The front and stiffer in the rear. I am running nitto 555r drag radials, sfc, aftermarket lca and panhard, have 12 way adjustable qa1s front and rear with I think the 300 lbs springs in front. I'm an A4 car too, just looking for a starting point, maybe what works best for you guys street and strip.

Never really got to dial mine in at the strip (0 front, 4 rear but rear was too soft, was bouncing on every shift) but on the street the car was fairly happy with front and rear at 6 or 7 for a little more firm ride.

4 to 5 on extension up front . 10 out back for compression

To clarify, I was running 12 way single adjustables, and @dawdaw is referencing double adjustable.

I am running the single adjustable. I just checked them again, I had the rears at 10, drivers side front at 5, and passenger front at 10 (wtf) I now have the rears at 8, and the fronts at 6, might move the fronts to 7, still a little bouncy.

Yup. I can't really remember how single adjustable go weather it controls the compression or extension but for a radial tire the setting I put above are pretty sweet. If you have doubles on the front run the extension at 40% extension 80% compression, rears 80% compression 50% extension. That will drive that radial down and keep it there. .. run the lca in the lowest or next to lowest hole and the torque arm in the 2nd to highest hole... pinion at -1.8 to -2.2. .. The nittos aren't as good as mickeys but those settings are as good as it gets.

How do the singles work? Adjustable extention with a set compression I'm guessing?

Single adjustable is both compression and rebound, adjustment for the same. The doubles are nice because you can independently set the compression and rebound. But the singles are still great considering how many people over the past........15-20 years I guess now.......have used them just fine.

Is this the settings you're using for the strip? Only reason I'm asking is I just installed a set of QA1 double adjustable on the rear of my car. I know ever car is little different, just trying to get a starting point on where to set for street and track.

From my experience, the rear shocks don't make as big a difference as the front. I always left my rear single adjuables in the middle. Also was involved heavily with George Baxter's low 8-second 30th SS convertible, and even though he replaced his front single QA1's with AFCO doubles, he kept the QA1 singles in the back. Don't know where they were set. Steve Spohn set the suspension up in his shop, and I don't ever recall anyone changing the rears, but I wasn't always at the track when he ran. Car pulled regular 1.2X 60's.

I know he was also running stock 4th Gen coupe springs, because Madman convinced him to use those, and I traded George my Formula rear springs for his Eibach Drag Launch rears.

Thanks for response. Stopped at UMI and they told me the same thing about stock rear springs. Said guys are running in the 7's with stock springs and drag shocks. He also mentioned guys run just as fast or faster with coilovers. I have a set of the double adjustable that came on a car a bought. I have installed them and plan on using them. Just seeing if anyone can give me some insight on where to start with my settings. Maybe I'll do what you said and start in the middle.
