It's that stupid rear wing that's bugging me the most. I like the idea of the driver adjustable front wings though. Should be an interesting season...roll on March
It's the wheel covers many a team put on to help the airflow around the wheel. I don't understand why they insist on painting the wheel spokes on them, it looks a bit off.
If I remember correctly, McLaren didn't bother with them last year but most of the other teams did. The benefits looked like they were rather marginal though.
Btw, I've heard Ferrari are having issues with the new car. KERS isn't working out for them, the front wing isn't up to scratch on performance and they apparently need to redesign their exhaust outlets as they break the rules...oops.
