I use this race as my quickest money maker; you can get gold on the first full lap if you time some things right. Like everyone has said, draft as much as you can. The Elise shouldn't be able to catch you when you start the race, draft the Z after coming off the banking, and when you're taking the turns, I find turning in later than you would think, and just letting off the gas instead of full on braking, keeps the car more settled and locked onto the racing line. You should be able to hover around 180mph going through the turns, and exit them around 185mph or higher. I just get into the slipstream of the Ford GT and Swift just before the end of the second lap, so they usually help me get comfortably under the limit. Good luck!
