I am also "frustrated" with chassis flex, as a former 1/1 scale person, but do agree about the true feedback and adjustability we lack when compared to full scale.
Here's another thing I am wondering about, 3* or so of rear toe. Why so much? never came close to that in full scale. Anyone have a "good" explanation, other than its possible, it has a positive enough effect, vs the negative drawbacks, so use it.
Thanks.
