I've watched 3 full races with the GX cars and I don't think either Mazda made it through the race without some type of engine issue(s). Hope they've gotten it all sorted out because the competition sure isn't going to be any easier in the prototype class. At least in GX they had control over the chassis.
Really looking forward to this amalgamation - can't wait for the series to get under way! Nice to see some press about it.
