I've got QA1s all the way around for going to the track but my car is about 80% street car. The rear shocks feel are so stiff you can't even push the car down and they are set to 0 and it bounces like a badly lowered car and it sounds like something is loose but I have checked everything. The fronts if not set to 3 will float like some worn out shocks. I have 300 lb springs in the front and stock springs in the rear. Is there something I can do to fix them?

Not knowing what else is in the rear of the car, sounds like some broken shocks to me. The car should easily move up and down when pushing on it, mine does. Add to that the bounce, I think you have a locked up shock--or some other issue that's causings SEVERE bind in the rear suspension.
Up front, the car should float on those shocks on low settings, that's what they are meant to do, transfer weight. You need to fix the rear first and re-assess the situation.

Stock springs are stock height.... But Koni's have a provision to allow a slight lowering (5/8-3/4") in front w/stock springs if you want to use it. We can lower the rear about 1/2" with other methods.
Stock springs are the best combination of not low, weight transfer, decent handling. Some lowering springs launch pretty well (the ones without ballistically stiff rear rates, like ours and a few others), but the car is still lower and the front springs stiffer and shorter and that doesn't promote weight transfer. That's what you DON'T want from lowering spring and it's why drag spring are very tall and very soft.

I have Strano springs with koni adjustables, I wouldn't trade em for the world, huge difference, and I can still launch just as good as I could before, but now I can turn like a go cart

but it doesnt say what spring rate they are (i.e. 275, 300, 325) Im looking for something a little stronger than the QA1 springs I have on the front end.
EDIT: I just saw his answer on another post

Maybe you missed it when he said--
"I am running Koni SA shocks with stock springs and Sam Strano sway bars and my car rides and handles great.... I have cut a 1.48 60' on them and ran a 9.78 @ 150 mph so I have no plans on going back to a QA1 shock."
Seeing how he had QA1's already (and AFCO's), I think he has a pretty good idea what he's after. A large reason he went to Koni's in the first place is because the car drove like crap on the road. Please correct me if I'm not recalling that correctly speedracer5532. And I think that might even be with not quite skinnies, but smaller than stock tires and wheels on the front. All reports are the car drives better and launches just fine too, which is what the original point of this thread was. I'd not call 1.48 shorts and sub-10's a slow car. How much faster does a street car need to go, and what are willing to give you in *streetability* to get it?

Sam the reason speed got the setup he did is because I just killed him in the turns and he hates to lose. The will handle now, but I dont want people to think they will cut 1.50 60ft times unless they have 1000 hp. Not many people no here will have speeds power.
His 60ft would be much faster if he had drag setup. As always you can have a drag setup or a handling set-up. Unless your speed and making 1000hp.

To bring this thread back on topic. The Konis are an excellent shock on the street and they do pretty good at the drag strip also. When I put the Konis on I looked around and found a pair of the rubber top shock mounts so I could put the front AFCOs back on fairly easy when I went to the track but after seeing how well the Konis performed for me I will be selling my AFCOs and QA1s.

Ya with 1000HP just about any shock will do well. And if you want to go faster all you do is turn up the boost. Not everyone has that option. your 1.5 60ft sould still be 1.2. With your set-up you should be 9.3 not 9.78.
