A lot of effort over the past few weeks but we finally got to shake down the Radical SR3 we built for the 25hr of Thunderhill. Very thankful to all the guys that have made this possible. Now for the inspection before we head out to California. . . . . #radicalsportscars #SR3 #10 #thunderhillraceway #thunderhill25 #night #racing #cold #chicago #sparco #bellracing #aimsportline #fuelsafe #dunlop #NWR
