V3.2 uploaded, improved the roll stiffness equation and shock piston starting setup equation. See how my setup is balanced front to back Still haven't got to the track but hope to be there in one hour.
Found others explaining that softening one end of the car lessens weight transfer, so when I went for the mid hole in the rear arm for the shock my JQ transferred less weight side to side and that's why I gained steering, as I said before tire load is very important and it should be what we should be after and not straight to softening front or rear springs.

Fresh from the track, it was back to how it was I can't believe how much difference that change did to on power traction, now it almost pushes on power and has actual good traction, using the outer hole in the rear arm -a higher suspension frequency- a complete opposite of what you read around here.
That's why most setups and complaints are easy to debunk. Racers complaint that X car has no traction on/off power/doesn't steer, that the front/rear suspension was softened and it doesn't work so the car is a POS. Well, there it is, make the car press the tire down, increase tire load not decrease it.
Another thing I want to address:
-Springs and pistons control chassis up and down movements, roll centers and ARBs control roll and kick-up and anti-squat control front to back and vice-versa weight transfer. If you do suspension tuning by tuning roll with springs/shock oil like 95% of racers out there then your car will always look "bad" on track. For example, ever see a MP9 with the stock setup going around a track? Looks like a pillow and has a reputation for being the King of rutted tracks. It has the total package, years of R&D, comprehension and understanding of what's going on the track and almost every buggy out there "can" be tuned to perform as good as it is but racers are lost in the shock and roll centers voodoo and mumbo jumbo. My Programming teacher told me to break a big problem into smaller ones. The car doesn't soak the bumps? Thinner shock oil, still too much then softer springs front and back to maintain balance. Doesn't grip? Induce more weight transfer by ARB or roll centers. Roll too much? Less weight transfer... Don't change shock package to control roll.

Motion Ratio(MR) again:
They don't have to be equal front to back, if the shock package is balanced front to back its all it matters. With that said, a good approach would be to run a setup that doesn't require an out of this world shock oil/piston combo, see the spreadsheet for a recommendation, and desired droop.

I'm happy when I see more and more setups with different front and rear shock pistons and racers trying to think outside the box. That's why I do this, to make everyone go fast and have fun.
