Did some tuft-testing yesterday.
As expected the back needs some sort of spoiler/kamback, and maybe extend the spoiler on the rear.
Front wasn't as bad as I expected it would be. Turbulence around the A-pillar, a high pressure zone in front of the windscreen. I think the new mirrors do help quite a lot.
Wat do you think? I have some short clips, if anyone is interested i'll put them on youtube.
