In a GT set up as an FAV car you must used a high clearance pan such as available from Armondos or Aviad. Some replicas such as CAV mount the engine higher so a standard pan will clear the road. This is also a factor of transaxle, the original ZF has the input shaft under the output, the Audis, etc. have the input above the output which puts the engine crank and thus the engine higher in the chassis.
