first tank after getting the c-rex back on the road. New suspension, set at stock height all around. Added sunroof, replaced upper/lower balljoints in front, outer TREs, fixed distributor leak, replaced trailing arm bushings in rear. No alignment has been done at this point. Quite a bit of racing around, just for the pure joy of having my go-kart back on the road again!!

First tank data after new motor/tranny work. Beat the Rex pretty hard during this week, "breaking in" the new clutch and motor. A bad tank to use as a baseline
