Default Spring rate vs shock "pack" to prevent chassis slap???

I am in the finishing stages of putting together a buggy (Tekno EB48). I thought I would try the spring rate balancing technique per this thread: tune with camber links.

I have the buggy fully built except for no oil in the shocks. I have the rates very nearly balanced, the only problem is it seems way too soft. If I drop the race ready buggy from 2" off the ground it slaps very easily. It is a bit heavier than typical since I have mechanical brakes (+servo, +brake kit, +steel spur, +clutch&bell).

I realize that the shock pack effect will help prevent bottoming, but how much should be pack vs stiffer springs?

How to you determine the correct spring rate regardless of oil weight or piston config?

The Tekno EB-48 has special tapered pistons like on no other RC Car.
With the steep cone shape you should be able to adjust chassis slap a little easier....If you go to their site http://www.teknorc.com/product-categ...-option-parts/
they have new machined pistons in different damper rates to adjust pack.

So how do you determine correct spring rate? Most kits have multiple spring rates available. How do you know which one is right?

It does not seem right to me to just tune w/ oil and pistons.

I need to nerd out more than that!

I dont know if there is a so called correct rate for every situation. Lots of people use spring rate to gain or reduce grip on one end or the other, and the same thing goes for oil to a point. I guess there has to be a give and take.
