I've had a couple of requests for my 342 MPH settings, which have now been modified to 343.53 MPH. Before you say "that's got to be a typo" when you see the settings, read the explanation at the bottom.
Tires: Super Soft
Nitrous: Equip (50)
Turbo: Stage 4
Spring Rate: 4.0 front and rear
Ride Height: 55 front and rear
Shock Bound: 1 front and rear
Shock Rebound: 1 front and rear
Camber angle: 12.0 front, 0 rear
Toe Angle: 0 front and rear
Stabilizers: 1 front and rear
1st gear: 3.109
2nd gear: 1.871
3rd gear: 1.282
4th gear: 0.935
5th gear: 0.716
6th gear: 0.513
Final: 3.680
ASM oversteer: 0
ASM understeer: 0
TCS: 0
Downforce: 38 front, 53 rear
LSD initial: 60
LSD acceleration: 60
LSD deceleration: 60
Super soft gives you the most traction. Springs and shocks are set at their minimum because of the speeds. If you turn them up, the car wants to bounce at around 275 which slows you down. If they're minimized, the car floats over the bumps. Toe is at 0 because you want max speed, not stability. This makes the car harder to drive but at the speeds you're reaching, it won't matter as downforce keeps the car straight. Ride height is minimized so air doesn't get under the car. Stabilizers are minimized because they cause understeer if you turn them up. The gearing is key. When you hit 6th, you'll initially think it's too low, but once it gets going, it picks up pretty quick. TCS is at 0 because you don't need it in the corners with no shocks. Downforce is minimized because you want as little drag on the car as possible. The LSD settings I put there just for the heck of it. It picked up a couple MPH when I changed it, so I left it there.
Camber has everybody going "WHY?!?", I know. The reason is rolling resistance. With the camber set that high out front, only the edges of the tire are touching, so there's little resistance on the front end. This makes the car hard to turn, but on motor on the test course, you'll never notice it. Camber is at 0 on the rear because you want the tires as flat as possible for maximum usage of the power.
The 343.53 number comes from a max speed run on the test course. This isn't a full lap, it's like 3/4 of a lap. So, run motor all down the front straight, and through most of turns 1 and 2. As soon as turn 2 start flattening out, hit the nitrous. The car will float to the wall, but you should be able to steer it off the wall. If you're at 295-300 when you hit the tunnel, you'll hit 340 by the time you get to the finish.
These settings are just something I threw together in about 10 minutes of work. I will continue to work on it and see what I can do. The key here is that I am NOT cheating. I could probably get one to 400 with infinite nitrous, but that's not the point. The point is to find out just how fast you can get one to go without Gameshark helping a brother out
