The parts store at Haas HQ is looking a little threadbare, according to Team Principal Guenther Steiner, and as a result he's given his drivers one guiding principle to get them through the Canadian Grand Prix: "No crashes this weekend!"

Haas’s crash-strewn start to the season – in particular with Romain Grosjean, who had significant shunts in both Baku and Barcelona – has left a dearth of spare parts available to be bolted onto the Frenchman's and team mate Kevin Magnussen’s VF-18s, with Steiner describing the spares situation as ‘very lean’.

"The spare situation with old parts, it's quite bad," he said. “I think with the spares position we are in now, we had a few crashes lately, so that never helps you. And at the same time we were planning to do the upgrades, so you had both things going on and that's why you end up with no parts. It's one of those things.”

So thin on the ground are Haas’s spares currently that Steiner revealed that the team opted to remove certain parts in Monaco to avoid the risk of damage – something that would explain their lack of pace over the weekend, with Magnussen and Grosjean only managing to finish 13th and 15th places respectively.
