Well what ever you do it should be with a Jeep and it should be cutting edge. Other wise your just building a buggy and it would no longer be a Jeep Lab item. If that makes sense. What if you took Betty and turned her into a full race Hammers jeep? I don't think I have seen a Show quality 4 door racer yet besides Mel's. You have the power already and the chassis. You would need a real cage and some race axles and a full suspension rework. Kind of like Mel Wades EVO1 but pretty.
