Worth pointing out the 3.7 V6 Roadster doesn't suffer from grounding issues generally, the engine being designed for fore and aft mounting. Would have to go back a few years to when mine last touched although the most severe speed bumps will catch any Mog out. Having reduced length seat mount bolts and side exhausts helps. The lowest point now is the inverted U section gearbox cross brace were it dips for clearance.
