How much frame to rear axle clearance You got

How much frame to rear axle clearance do you have? I have 2 inchs at best. Some say 3 to 31/2 is better to stop bottoming out. I got 250 lb springs coil over and 350 lb springs. Its a 29A sedan. I dont think that the 2 inch is enough. Problem is I have to jack the ass end of the car up. Makes it too high in the ass

 

2 inches isn't enough. Anyway to modify it?

 

Thanks Choppin all I can do is lift the ass on the lower shocks mounts.
Or take off the body and notch the body frame deeper. A lot more work. Thats for the winter not now.

 

Post some pics up, maybe we can come up with a better "fix".

 

3 inches should be minimum. Bump stops are your friend...

 

I have very little and the new fad diet aint working either!! my buddy gave me a set of 90s chevy truck cab mounts, took the larger nonmetal one, sliced it on the band saw and popped it over the axle...works great! i wanted to step up on my spring weight but didnt want to make a pogo stick out of my roadster!

 

Thanks guys I bumped her up on the lower mount one inch. I have a good 3 1/2 inchs now.
