Well that did not go according to plan. Jefferson wound up getting run in a reverse configuration. The course started at the #11 corner station and ran clockwise until corner station/corner #1. I only managed to get 2 honest runs … Continue reading →

Snap oversteer on drift transitions

Posted on 08/10/2016 by Yoshi

Haven’t written in a while so let’s give this a go with some setup theory. This past weekend I got to drive quite a few cars. But the two that stuck out were an E36 and E30. The E36 was … Continue reading →
