I've found a way of ducting exhaust right to the diffuser edge like in 2011 and created a new wheel fastener that could allow sub 2 second pitstops see them here --> My 2013 F1 Concept Project
As promised here is the first update for the 2013 car. It is a rear wing; however this shows the wrong picture, as the profiles are on top of eachother , instead of well how they are meant to be.
Sorry. I think I already said that the aerfoils are incorrect but maybe I didn't. Anyway, I fixed that straight away after Wesley told me; I just cba to post a new picture, unless you guys wanna see it?
