| Re: Ground Clearance: SPF vs 60īs GT 40 We have run a GTD both on track and road for some 5 years now with a 120mm ground clearance to the chassis and with the wet sump 40mm below the chassis ( i e 80mm clearance to sump pan ) I got a bit twitchy about the sump pan hitting the road on some of the more extreme roads we have driven, including the Isle of Man hill climbs, and made a sump guard / shield below the sump pan, had it specially painted to show any witness to grounding, and in the first year never made a mark on it, so it got thrown over the hedge and never used again.
