The 11.5" wde tires all the way around don't help eithet. As a walking book of NASCAR specifications and knowledge, this kinda disappointed me. I also dislike how they called Daytona 'the biggest' (it isn't) and Infineon (or Sonoma) Raceway 'Sears Point'. I liked more the article they did a couple years ago on hanging out with Junior. That one was pretty cool.
I should also let you know that a car with a regular speedway engine but a restrictor plate aero package will top out at about 240. 153 is rediculous. But then again it has a Sonoma gear ratio package, not to mention a high-drag, but high-downforce aero package.
