I was at the race were jilles stripped the gear.
It's a very rough track, it was also very hot last weekend.
On my own car i had a piece of tar stuck between the gears which had come loose because of the heat.
Maybe this also happened on jilles car, but he just went full throtlle in first gear on the back straight.
Every one waited when the engine gonna blow up.
But he was lucky that the track isn't really fast, second place driver could really come close on the straight but jilles was faster in the corners, and the guy who came in second had some bad luck in the pits during refuelling.
