i race modifieds and out track is open every wednesday for practice. I will take my crew out towards the end of the year and let them hotlap.
Best advice, get a pitpass find someone who will take you in and do all you can to help.
As far as what does it take to get noticed. Unless you have deep pockets or have a friend that has money but doesnt want to drive, i wouldn't hold my breath waiting for that big break.
I started racing modifieds in 2002, in 2005 I raced 360ci sprint cars (ASCS Rules), was 2nd in points going into the final night and ran out of fuel running 3rd in the A, was rookie of they year in 2005, in 2006 I won the track championship, sold everything and went back to modifieds for 2007 and 2008.
Sprint cars where too expensive, I did have success, but I never tore anything up. That was the reason for going back to modifieds. I'm still waiting for that phone call that I hoped someone noticed me and wants me to drive their sprinter. But I am a realist. It's probably never going to happen.
