Throw back Thursday: Richmond Indiana Street Race 1980 with Susie Osterholt (r) and Cheryl Fehring (l) at the scoring table doing our job the old fashion way with pencil and paper. Transponders made life easier many years later.
Under the table Rachel Ruby (l) and Michelle Fehring (r). The bees were swarming and Michelle was stung under her tongue as she went to sip her drink. Still having fun!

We have ran SMC clutches since 2004. The bullet, the vortex all were and/or are great ! Many wins, many titles..... look no further for awesome clutches and even better customer service !!!!!!
All 3 Junior UAS drivers had SMC drivers at the Unlimited All-stars Grand Nationals! If you are going to run with the best, you use the best! 1st James King , 2nd Daniel Watkins , 3rd Donnie Austin. All made possible by Shannon Halbert!
Thanks smc for a great clutch
Picked up the win Friday night at Fremont Raceway! Rocking my SMC Clutch! Thanks guys for an awesome performing clutch!
Got the new vortex black and I gotta say WOW . This thing is bullet proof and still hits hard. I have ran all year so far with out a rebuild and still pullin on starts . Looks a lot like the old black but works even better. Great job.
