Default Drag bag help

Just installed a set of drag bags and a set of nitto dr's. I would like to know what psi you guys are running with these. Tried 15 and just spun with no traction. Then went down to around 8 and got wheel hop again. Best 60 ft so far is 1.9. Just looking to improve this. My mods are full exhaust and intake.

Each car is going to be different, I have had guys run them anywhere from 15psi to 30 psi. What kind of tires and what pressure are you running your tires at? Tell us a little more about the car and we can definitely help you out.

I run mine at 10-12psi.

For the tires, on the street I ran 28psi and 20-22psi at the track.. Just depends on track conditions. 28psi seemed to get the best life out of the tires. I've had tires last 15K, 13K and 10K(still have tons of tread left)

It's an auto with stock suspension other than the drag bags. Full exhaust and intake.

Any spring upgrades on the rear or are you still running stock coils? I ordered Pedders Drag springs and wow...what a difference even on my stock car. Didnt really change the ride either.
