1)If the frequency in the front is say 1 then I would want the rear to be somewhere around 1.1 to 1.2?
2)Is this front to rear ratio more important for a shorter wheelbase rig like a samurai, Jeep, or baja bug?
1) Yes, at least for speed work
2) Actually, no. The faster you're going and/or the shorter the wheelbase the less important the difference front to rear. It has to do with the time between the front and rear going over the same bump. The longer the time between front wheels and rear wheels hitting the same bump (which you can calculate as (0.0568 * wheelbase in inches) / speed in mph ) the more by which you want the rear suspension quicker/stiffer/higher frequency than the front so it reacts faster and catches up and therefore the front and rear tend to act together instead causing pitching up and down.
I'm going to add a bit more to the article on this and will post it up here too. Should be done today.
