IIRC, increasing scrub radius helps drifters keep the steering angle while sidewards, without much effort because the inner tire is so positive cambered and castered that it follows the momentum of the car.
I don't mind a little more offset for road racing and autoxing, the added track is usually worth it. I have some 15x9 with a +26mm offset coming for the miata, and stock is 14x5.5 with a +40mm offset. Quite a big difference! |
It's for a daily driven application. A change in steering effort is perfectly fine with me, but I just don't want to ruin the suspension geometry for what's effectively going to be an aesthetic modification.

That's what I figured needed to be done, but none of my textbooks or online information had any relevant information. Thanks for the help
