Shock setup and drop test

[Chevy-SS]

I just bought a set of MSR5 Integy shocks for my race Maxx. My local race track has some sizeable jumps. Has anyone set up a set of these shocks for jumping? What oil and pistons you using?

Also, for you racers and jumpers out there, do you ever use a drop test? You know, drop the whole truck from a foot or two? Or perhaps just lift up one end and drop it? If so, what is your drop test and what kind of results do you look for? Do you want the truck to hit with a thud and sit still, or should it bounce? Also, kindly include what kind of jumping or bashing you are doing? I am most interested in developing a drop test that will simulate good-sized jumps.

Cheers :beer:

If you set it up so it doesn't bottom out from a 2 feet drop, it will probably be too stiff for anything but big jumps and flat landings. I set up my cybermaxx for the big jumps in my yard, and it was undrivable on a rough local track.

sounds sweet, got any pic? i was thinkin about switching to using just 4 buggy shocks or supermaxx shocks.

The drop test I use with my buggy and might also work with a MT race setup. Using the flat surface as 0 degrees and if the buggy/MT was completely vertical being 90 degrees, life the front or rear up so it's at a 45 degree angle then drop. When it comes to rest the arms should be parallel to the surface. Keep in mind that this is just one of many methods and of course track conditions will dictate how much or how little rebound you want.
I think the preferred method is to observe the machine on the track while running. Trial and error. Dropping something from a static height of 4 feet doesn't take into consideration that on the track you have two elements to do with. You have a vertical drop with forward momentum. Below is a good link about chassis dynamics. Weed through most of it and you'll find some good stuff on shocks/suspension setups.
