NASCAR 2023 CUP Series (Next Gen)
NextGen Quick Setup Guide
NextGen Quick Setup notes for ovals.

1) Ride Heights are one of the biggest adjustments to the NextGen mod. Lower gives you better downforce which makes the car stick to the track better.

Typical starting ride heights are:
LF: 1.25
RF: 1.375
LR: 1.125
RR: 1.5

What each ride height does:
1) Raising LF ride height makes it looser.
2) Raising RF ride height makes it tighter.
3) Raising LR ride height makes it tighter.
4) Raising RR ride height makes it looser.
and vice versa.

Ride Heights effect the wedge in the car plus the downforce, depending on how fast you're going. The faster the track the more aero downforce plays a part.

2) Make the springs stiff cause the car is already on the ground. Springs are rated at pounds per inch of travel. The NextGen car only travels about an inch. Right side cornering weight can be 3000 to 4300 per wheel and left side can be 1200 to 2500 per wheel. So that's about the spring rate you need to run just to keep it off the ground.

Typical starting spring rates for oval:
LF: 1500
RF: 4000
LR: 2500
RR: 3500

Tracks with more banking use stiffer left side springs. Like Bristol, Dover, Texas, etc. Tracks with less banking use softer left side springs or maybe softer right springs too. Like New Hampshire, Pocono, Martinsville, etc.

3) LF bump stop helps it turn. If you need to use this then a typical setting for this is .625 give or take a click or two. All other bump stops are typically 0 and are very tricky to adjust for little to no gain.

4) The most important thing with NextGen cars is drive off the corner. You can't drive them off the RR like the older Cup, xFinity, and Truck mods. If you're heating up the RR tire more than the RF then you're in trouble. You can adjust the Differential settings to help with this but start with
Pump=0
Power=50
Coast=6
Preload=10Nm or sometimes 140nm
The typical number to change is Power. A lower number gives it more bite by putting more torque to the inside (LR) wheel. But the downside is the LR will heat up more and wear out quicker, then you'll be loose-off later in the run.

Nose Weight:
50 to 51.8 % but typically in the range of 50.4 to 51%. More nose weight makes it more stable but tighter.

Sway Bar:
Typically, 1.5 to 2"
The NextGen cars don't seem to like a lot of sway bar. Smaller sway bars make the car turn better. Sometimes it's a tradeoff between sway bar and nose weight to get your balance. But ride heights are the most important adjustment.

NOTE:
The Oval Default setups have been thoroughly tested and with little to no tweaks, are winning setups. If you deviate too much from the default settings, chances are the car will become out of balance and not drive very well.

On road-courses, we only have Default setups for Watkins Glen and Sonoma. There is a generic road-course default setup but that is only a starting point.

Wheel Settings are extremely important. I've found that changing the Wheel Sensitivity setting in rFactor to 80% instead of the default of 100% helps me save tires and run faster. You may have to adjust the Steering Angle in the car setup when you do this. The Steering Angle adjustment controls how sensitive the steering feels overall. Whereas the Wheel Sensitivity adjusts how sensitive the wheel is around center. Spending time on wheel and force feedback settings can make a big difference in how the car feels and handles.
