Having zero toe doesn't mean greater resistance in a straight line, it means less.
Think about it.
When the tyres set to toe-out, in a straight line you are pulling both tyres slightly sideways which is why the inner edges scrub off so quickly.
I did say," if anything!,"
and the reason for a zero'ing the track potentially increasing drag? caster angle offset, which "BIG-Mac"-ferson
has inherently because the hub carrier is flapping in the breaze by a compressed spring and shock!!! to get all the bits right and reduce the compromise, full wishbone! not possible I know!
Obviously excessive toe out would ruin the inside edge of the tyre, taken, but it's not normally out by a great deal, but Camber angles that are created as a result of lowering the vehicle (as in TI etc) cannot be compensated by toe correction!! ever!! period!! !
NOw, if you're after a car that goes round a corner, with good turn in, and increased grip...camber high, and toe in! Simples! no good for road use!! doh. have fun out there!!
