Sorry for being late with this, but here is the settings that I got from another thread in these forums...NOTE: the settings are formatted like this --> **Tuning Option** -- Value for Front/Value for Rear ....here it goes...
First, Get into your NASCAR of choice, and go buy the Chassis Stiffing Bars for the car. It is a one time purchase (and the only purchase aside from oil that you can make for these cars). NOTE, this feature CANNOT be turned off, but is worth the money when driving the car. NEXT...go tune the beast...
In Suspension:
Ride Height -- +15/+15
Spring Rate -- 18.5/18.5
Dampers (Ext.) -- 8/4
Dampers (Comp.) -- 8/4
Sway Bars -- 4/4
Camber -- 3.0/3.0
Toe -- 0.0/0.20
======================
In Drivetrain>Limited Slip Differential:
Initial Torque -- 60
Acceleration Sensitivity -- 60
Braking Sensitivity --15
======================
In Body/Chassis:
Downforce -- 20/40 NOTE: This is the minimum setting for Downforce on the NASCARs...trust me when I say it, "You will notice a wobbly handling, but it is well worth it to learn how to control your car at this setting....and I use the regular old controller to race and am fairly good at it"
======================
In Driving Options (the "tuning knob" in the Racing/Event Lobby)
Turn off ALL, and yes, I do absolutely mean ALL Driving Enhancements
Tires -- Racing Soft
ABS -- Set to Zero
======================
I hope these settings work for you like they worked for me...happy racing, and hope to see you out on the track...BTW, my username and Play Station 3 ID are the same...
