Same here chased E.T.s for years , now the car is slowed down about a second with a modified Moroso mechanical ( adjustable bolt) stop. Never had a problem dialing the car I can adjust for slower and faster with a 7/16 wrench. I looked at the E.T. Genie and the other one with a dial to adjust the plates but wasn`t sold on them. I have my setup pretty well set after 4 years/ seasons of running this way. My past 4 seasons have been the best in my racing career with more Wins and rounds won than the previous 20 plus.Being one of the fastest cars in the class does have its advantages. BTW I`m running the same car (11secdart) in both classes on the same day. Also no electronics are allowed except transbrake and/or two step.
