No,it's not 10.50 index. It's a small organization of slower 10.5 racers (Usually not faster than 4.60's in the 1/8) with a low payout,about 1500.00 to win but pays back to the 8th car. Cars range from 5.60's to 4.70's and have a good time with some close racing. the last 2 winners were only going 5.25 to win it ! Tracks are slippery is the equalizer. I will be there on saturday.
