I back-to-backed the mg with a stratus 2 last night on asphalt in modified (schuie mi2)
I felt like maybe the stratus had a touch more steering, but the mg was certainly rock solid. the rear wing area especially seems to work well. Overall I found it very safe, very confidence inspiring that the car wasn't going to do anything too weird.
I'd happily use it again - particularly on big/high speed tracks.
Geppetto, Are you racing indoors on carpet or outdoors on asphalt? I just bought a MG body and want to try it out his weekend on an outdoor track that is more technical than some of the other outdoor tracks in the area.
