Editing NFSHS Car Performance Tutorial

- By Justin Martin aka IH8COPS

 The purpose of this tutorial is to teach people how to edit the performance file of NFSHS cars. Please do not email me with questions regarding this tutorial, I will not respond to questions about car performance editing. If this tutorial does not answer your questions, try posting a message on the Total NFS Message Board

Part 6: Steering Steering/Turning Min. Steering Acceleration - Like the Lateral Acceleration Grip, this seems to have a effect on nimbleness. It does not seem have to affect grip. In general, i'd keep this between 14 and 16, and use the Lateral Acceleration Grip to adjust the nimbleness of the car. However, if you think your car has too much grip, you can try reducing the Lateral Acceleration Grip and increasing the Min. Steering. This will slightly reduce the grip, but without causing the slow, heavy steering associated with low Lateral Acceleration Grip settings. Turning Circle Radius - This is the cars turning radius, ie, the radius of a circle a car would make in a full lock low speed turn. (like a u-turn) In typical fashion, EA seems to set their car's turning radius to about 1 to 1.5 meters smaller than the car's real turning radius. Set it to the cars real turning radius, if you can find that information. If not, then set it to 6.0 for cars, 10.0 for trucks/suvs. If you are doing something like a tank or a bulldozer, setting this to 0 would give the pivot-around-a-point low speed turning such vehicles have.

Gradient Understeer - This sets the amount of understeer/oversteer a car has when you reach the limit of the car's grip. 1.0 is neutral, numbers lower than 1.0 will give understeer, numbers higher than 1.0 give oversteer. The settings that give the appropriate amount of understeer/oversteer will vary slightly depending on other settings, but here's a rough guide that should get you pretty close to correct.

0.70 - Dump trucks, other mega-understeer vehicles
0.80 - full size trucks, old large cars, bad handling muscle cars
0.85 - muscle cars (without anti roll bars)
0.90 - muscle cars (with anti roll bars) typical fwd family sedans
0.95 - modern muscle cars, most sports sedans or good handling family sedans, some sports cars
1.0 - neutral; most sports cars, sports sedans
1.1 - sports cars with somewhat wild tails, like Porsche 993's
1.2 - wild handling rear engined cars, old Porsches & Corvairs mostly

Here's a sampling of what i've set some of my cars to:

1957 Olds 88 - 0.80
1970 Porsche 911S - 1.19
1975 Porsche 911 Carrera RSR 3.0 - 1.20
1981 Chevy Silverado - 0.80
Lotus Super 7 - 1.0025
Toyota MR2 Turbo - 1.00
