It's the same way across different brands, pro setups where the front collapses and the front outside tire hooks in turns and lift the inside rear wheel, provoking rotation and then when it settles down you just punch it. The B4 is that way, the XXX, the B44, most 1/8th buggies...
Spring wise I haven't found a car that was close enough with the box setup, most of them are front biased. Pistons only now we see drivers using staggered piston hole diameter front to rear, most still swear about using same piston setup front and rear.

And what they came up with was what they used going forward on their cars. I think that interview pretty much demonstrates the tuning knowledge they have.
They knew the basics of where the roll center height should be and that long arms are better. They have to, the front uprights are a sign of that.
I'm happy with the balanced everything method, still have a B5R I want to test but it shouldn't be too different than the B4 I had. One question to Fred though, do you have to run less rear toe on your new setups? Both 1/8th buggies I ran last year I end up with 2º toe and sometimes I get away with less.
