Has anybody tried soft springs in the rear on 1/4 mile semi banked asphalt

My question would be softer than what?
Obviously, you don't want to bottom out the springs.
As an average, I see a lot of people running 175/185 Left and 185/200 Right.

I'm not a chassis guru by far; But, I think it would be some trial and error to find the right combination that would work for your track.
I know several people that are running 175 Left Rear and 185 Right Rear. We had one guy experiment with springs as soft as 140 on the rear and he could not get it to work.

If you have some spare springs and shocks laying around, perhaps set them up and start lowering your spring rates by (lets say) 5 pounds. At some point, you would get as soft as you can go with the rear springs. Then, I would assume, that you would have to start playing with the front springs. I can certainly see where a spring and shock dyno would be fun to have! I would also guess that you would need to take a lot of tire temps and see what they are telling you.

If you watch the shootout, soft enough that the RH side steps are basically dragging the ground, probably 100lbs or less.

Your average racer is in the 250/275 neighborhood.

Jason,  If they are running 100 lbs or less up front at Shootout, what are they running on LF and for rear springs? Thanks!

Definitely not an expert, but you can definitely tell certain things from pictures of top runners.

They call this coil bind setup, they run at the flat 1/4 miles like charlotte, Atlanta, etc. My understanding is it takes some getting used to because you have to set the car going in and mash that RF spring and keep it mashed the whole corner otherwise you upset the car. I've never driven it, but I hear the guys that do it well are hard to beat. I know a guy won SP in 2015 with a conventional setup, but coil bind is normally superior at Charlotte.

I think they run a 90 RF, not sure about the others.

Coil binding is extremely prevalent at Charlotte. I think the only ones running it at Atlanta are the guys that come down though. Most of the cars here are setup conventionally (250/275, 175/200 ISH)

How do you guys do against the fast guys running coil bind? Can you guys beat top 3 shootout competitors? If not, you will probably have to go coil bind at some point.

The guys running soft springs are also the same guys that sell used cars for 15-20k, so there is a lot of money/parts that go into this discussion as well. That makes it harder to determine where the real speed advantage is.
