Anthony Magagnoli driving demonstration laps in Luke Pardi's NASA GTS3-spec E46 M3 at NJMP Thunderbolt during a Jeffapalooza test day, with a fastest time of 1:25.77.
Anthony... amazing lap! Can you please tell me what final drive you are running and your car's weight. This will be the second year tracking my e46 M3 and I'm struggling with the oem final drive. The car on most straights is just sitting forever in 4th. It's like sailing, lol
John, I'm not sure what final drive this car had, but I can figure out what you'd want to run if you have some in-car speed and rpm by distance data. Ideally, you'd want to be fully topping out 5th gear, while ensuring you're not necessitating additional shifts in inconvenient places. If you'd like to order a diff through me, I'd be happy to calculate it out for you and identify the ideal ratio for the tracks that you run. You can email me at Anthony@DriveFasterNow.com.
