Is ground clearance a problem on the Roadster?
Bob.
Not on the 3.7 version.
I have a Brooklands Roadster 3.7 which has done 6500 miles , mostly on the run from north Scotland to Spain last year. The cross member supporting the rear gearbox is the lowest part of the chassis and I have grounded it on numerous occasions . It even grounded coming out of the garage until I built up the gravel to create a ramp. So you will not damage the sump but continuous scraping of this chassis member may well lead to some form of long term damage. I've discussed a bespoke steel plate to protect it with Revolutions , yes it will reduce the ground clearance but protect the gearbox .
