How can you change the spring from firm to soft for the drags in 10 minutes? Wouldn't you have to do the whole procedure again to change the spring ~35 min per side?
I wondered the same thing but instead of asking I just assumed that all you would have to do is take the two top mounting bolts out, swing the unit out (again, assuming there is enough room) and then remove the spring and install the new one. If that`s the case then 10 minutes sounds about right. Even less time with air tools.
wrenchjeff is mostly correct.

Remember that the 45 minutes per side included removing the stock suspension, assembling the coilovers, and mounting the new coilover.

To change a spring:

Lift car and remove wheel (already doing this anyway when changing to drag radials at the track).

Loosen top spring mount all the way by hand - 30 seconds?
Remove one 3/4" bolt at bottom shock mount - 1 minute?
Remove lower spring mount - no tools - 10 seconds?
Compress shock by hand move away from lower control arm, drop spring, Replace spring - 1-2 minutes of jimmying stuff around?
Reinstall bottom end of shock in lower mount, tighten 3/4" bolt - 1-2 minutes of wrestling stuff around again?
Reinstall lower spring mount - 10 seconds?
Retighten upper spring mount by hand - 30 seconds?
Install drag radials.

Done.

I need to do some work on my car, so maybe I'll actually time the process tonight. But that's all there is to it.

Thats cool. I thought that maybe there was a simple process and I was overlooking it.

Yes - see my new thread. I timed it last night: 4 minutes 30 seconds. Not including changing the tire. So if you're changing to drag radials at the track, add 9 minutes total (both rear shocks) to your procedure and you can completely change the rear springs.
