I do believe AE had posted on FB that the team drivers were running Centro C4.2's..could be wrong though...
Went back and double checked on FB....AE says multiple times "Centro converted B4.2" So I'm not exactly sure what that means lol. Looking at the shock towers of the C4.2 (front is carbon) and the C4.X that the AE guys were running at the shootout...it appears that they are running the C4.1 (stock AE plastic front tower)
Things that make you go hmmmmm....
lol
