Jan Magnussen is certainly all about precision.

The Danish Corvette Racing star did his best to find the absolute limit on the streets of Baltimore in the first session.

Magnussen shaved a coat of paint off the mirror and inflicted a similar very minor scrape off the front and rear of the car.

With a new wider front end on the Corvette this year, he jokingly blamed the incident on his No.3 machine’s new dimensions for 2012!
