Time to put down the welder and race in Moab!

Time flies when your sole focus and energy is going towards the build of a brand new racecar. But now the Proving Grounds Racing crew is only a few short weeks away from setting down the welding tools and heading out to the next Ultra4 race. And as an added twist, the western series race for the season was moved from Reno, NV to Moab, UT – an exciting change for the team since Easter Jeep Safari was cancelled earlier in the year. Though spending quality bonding time in the garage has been great, the team is pumped to get back out on the track and kick up some dirt!Check out the latest video on the 4400 build!
