Another thing to consider, is the value of Technique and Speed when Evaluating Under/OverSteer.
MOST cars will Understeer at Lower speeds.
The Higher the Speed, the More Likely a car is to oversteer with any given combo.
The Trick is a combp of technique, AND Taking into account the average speeds at which you will be cornering.
If you want a Neutral car at 80 MPH, you may well continue to Push/Understeer at 20 MPH in a TIGHT Hairpin.
If you're set up for Tight Auto-X, you may well end up BACKWARDS at 80-90 MPH in an "On the Edge" Corner.
Technique can affect response at ALL Speeds.
Even Pro's have different techniques which lend themselves to Over/Understeer.
You have to find a set-up that's Right for YOU, AND for the Speeds at which you're concerned with "Finding the Edge".
BTW, on my S2, I have the SVT Bars from the Factory, and SVT Springs which I've Added.
MY Car is set-up for more rotation at Lower speeds, so I have Koni Yellow Rear Shocks set at Full Stiff.
I Hope to get Fronts soon, to allow more adjustment.
Right now, I'm definitely a tad Tail-Happy, but not Overly so at most speeds that I see on Backroads.
