It’s an Maranello MK3 chassis. These chassis are mostly used on shifter karts and are very competitive in the shifter classes. In non-gearbox classes however they are super rare to see. I am the only one using it on the whole grid of the Dutch championship so i can’t really compare. However the chassis is really close to a CRG and CRG chassis are very common and competitive here in the Netherlands. So i feel like if you understand it and drive it right it can be really quick. I never drove on an OTK though.
Putin your head foward is actually worse for the aero it’s going straight up the Nassau in to your helmet they are designed to direct over your helmet when your sitting properly in the seat …. You’re the only one doing this and you see the kids do stuff like this … otherwise not bad driver .. hand placement and that is your only technique flaws if your hand placement is more even you will be less jerky and smoother which all adds up tenths over 20 laps makes a difference
