New to leaf springs. Any help would help out alot

[nebraskabowhunter]

I need to know what angle the shackle should be at on the left side at ride height. I have seen it stated at both 90 degree and at 40 degree. Which one is right?

[nebraskabowhunter]

Car weight is 2600 Running 1994 shocks on both rear with 175 multi leaf. And 1994 on rf and 1993 on lf. 12rf 14rr 10lr lf8

And one more thing could I put my left shackle mount at 51 inches and 53.5 inches and not be floating the RR. Rules will not let me float RR. Is that going to mess with weights and ride heights running in 2 differant holes right?

I floated my stock car and a mono leaf mod and put shackle at 40 degrees on both. The weights will change some. Tire temps will tell you alot.

This is what the IMCA rules say about the RR. Does anyone know if you could run a 15x7 and still run within the rules? I want to run more stagger. Thought this might be a good way to do it. "May use IMCA approved bead lock, on right rear only. External, steel bead lock only and it cannot make wheel any narrower than 8 inches and no wider than 8.75 inches".

I run leaf springs on an asphalt car and am faster than most even against guys running triangulated 4 links and 3 links. Loose condition can be fixed in many ways. Softening up the rear is one of them but with 175 lb springs I would start with shock and air pressure adjustment and make one adjustment at a time starting air pressures.
Whats the rule on sway bars? A smaller bar will tighten you up. Adjustable bars allowed?
Also, if your not running a track bar or watts link your rear leafs are binding and giving you a higher rate.
Another option is to stiffen up the front. Bigger bar or higher rate spring and or shock.
