I totally agree with you. But I must confess that the “learning a new car” excuse doesn’t seem to fit. Correct me if I’m wrong but slapping a new body decal that says Camaro instead of Impala doesn’t change anything race related. All NASCAR race cars use the same chassis, roll cage, templated body panels, wheelbase, tires, fuel delivery system, etc. The only difference is engine maker. Even the transmissions and rear ends are standard along with gear ratios mandated by NASCAR. They used to have a homogolution rule that forced them to run stock block motors. But now they’re pure race engines with little semblance of “stock” cars. Especially the Toyotas. Ever see a V-8 Camry on the street? They are purpose built engines with exotic internal geometry changes not necessary in street cars. I do think with today’s three heat format JJ needs to be more aggressive from the beginning and not lay back hoping to avoid aggressive wrecks at the front. As for HMS they weren’t patient enough with Kyle Bush as he gets more out of his car than any driver out there. But I do go on!
The car bodies are NOT all the same. The cars are extremely aero-dependent and if they are off just a bit they lose a few tenths, which is everything in racing.
In time the Chevy teams will get their cars sorted out.
