Hey guys.
looking for spring rates for my car. I have afco DA for the front that came with 14'' 300lbs springs and for the rear. stange DA coil over with 14'' 200lbs springs.

My set up is... iron 5.3 ported 241, pt88 turbo, 4l80e trans (no brake) py3400stall, MWC fab 9, Full spool, 3.50 gear, anti roll bar,

This will be 60% street car. looking to go 9.5 on the 5.3 and I have a built 365 just waiting to go in. looking for 9.0 or faster with it.

I feel the springs on the car now may be a lil heavy 300 on the front and 200 on the back, I put the 200 on the front he other day just to see how it would sit and with the springs NOT cranked all the way up it was sitting on the k member.
what are you guys putting on the cars to get to them to drive/60ft.
thanks guys

Had the car scaled? that would help. Chances are a 275 up front and a 175 in the rear on a coil-over setup is what will work.

After looking at your thread.. I think I would go with 300 front and 175 rear.
