Forza Motorsport 3 Tuning Setups
 

I made this because the other was just ridiculously cluttered. If you have a tuning setup, post the parts used (ie Race Exhaust, Street Intake, etc) and also the setup as well as the class (ie B-479). Leave the other thread for discussions/tips/hints/pictures/vids

Comments
The car is extremely stable and predictable, even while drifting. With the power it makes, powering over to drift an entire turn is no problem, and thanks to the rear-biased AWD, any drift that gets a little out-of-hand can easily be brought back under control by holding the car at WOT until the back end comes back around. I still need to upgrade the brakes, so I'll update this when I do.

Comment
Fairly neutral and predictable in turns, but the car tends to understeer slightly until the tires warm up (~2 minutes of racing). Oversteer is possible by going WOT mid-turn, and even during an oversteer event, the car is still predictable and easy to control. As a side note, I built the car to compete in Class A races, which is why the PI is exactly 600. More power, faster accel, etc. could be achieved by installing more race parts and tuning accordingly, but installing any more parts would put the car in class S or possibly R3.

Comment
Power-over, e-brake, fork stretching, it doesn't matter how you initiate a drift, this setup will have the car sideways and keep it that way. The car is extremely controllable while the rear end is loose and it's very easy to bring the rear wheels behind the front when you're done sliding.

Thanks Chris this is working awesome.

No problem. I might release my Viper and possibly my NSX (non-GT) tune tonight... I'm still iffy on the NSX; I spent about six hours tweaking the suspension until it handled perfectly.

And once I get my '71 Skyline the way I want it I might release that tune, too :D

does anyone have a good suspension tune for a RWD rex? I'm in a need of a good one for the WHOLE suspension for racing not drag
