How about using this for the age limit......

If you don't feel comfortable that your child is old enough to properly strap himself in to a sprint car, your child is not old enough to race a sprint car.

I have literally seen kids crawl into a sprint car then watched their dad lean in and tie their helmet for them..."Here's your sign"

I am a parent so I totally understand making sure your kids safety equipment is used properly but surely it takes more maturity to run 125 MPH than it does to hook up some belts.

Yes a mechanic should cinch a drivers lap belt....yes a HANS device goes on quicker with a second set of hands but come on...

Here is where I contradict myself........ I saw Clausen kick the crap out of a bunch of MEN in a micro at age 12. I saw Clausen in a sprinter at age 14, and I was at Wheatland, MO the night the front stretch fence tore Clausens cage half off the car and he got the neck injury......

I HAVE NEVER SEEN B.C. LOOK LIKE HE WAS IN OVER HIS HEAD!!! And I am quite sure Tim has been in the game long enough to know when Brian was ready for the next step, no matter how big that step was.
