Keep the car controlled and ease it around. racing your tits off just sends it into the gravel. i managed this after doing the 3 lap magic with the Ford GT Spec II, so i suggest attempting that first as it has silimar characteristics and gets Laguna imprinted into your head. i managed to pass this with a MAJOR offcourse excursion off the second to last sweeping corner where i understeered and flew into the gravel, missing the pitwall and just stopping short of hitting the RX7 in the rear. also the CPU seems to take the final corner a bit slowly, so get inside of them right and you can floor it to the finish
