“You possibly can think about these components are made to very excessive tolerances and also you’re making an attempt to reduce weight if you design the automotive, there’s no extra on a racing automotive. I suppose we barely stepped over the road and hopefully, now we’ve completed sufficient evaluation to tug us again to the opposite facet of that line.”
