For those who are lazy and would take an 'incorrect fix,' lower the spoiler angle. Just study the physics editor and lower the downforce to 800 pounds. It's not going to work and you are going to take a long time to get it right. To conclude this very important issue, use logic and edit physics correctly and stop using Chassis-0 to recreate the COT NASCAR car. So, when deciding what chassis to use, use logic and pick the right one. Papyrus used it as what if Chassis-1 was unrestricted. Chassis-5, the Chassis-1 with a Chassis-2 engine in it, can be modified for other things. Chassis-4 is road course and when using PTA physics, is the recommended chassis. That Supertruck.exe you might be making, might wanna use Chassis-3. It is a speedway chassis and is also used for some short tracks. Chassis-1 is the superspeedway chassis, it should be kept what it is and not changed to another type of racing. Chassis-0, known as the mysterious chassis, is most likely the Arcade chassis, so no touching that. Cup and GNS physics have the frontal area / fuel line together, so why not CTS for oval and PTA for road cars. Picking what chassis to edit with is important. However, NRE is researching ways to overcome that without switching to CTS or PTA physics or increasing drag. So, if you just drove your NR2018.exe, you just drove a Mazda Miata with 700 horsepower and 104 inch wheelbase. The creators of NASCAR Racing 5 increased drag to make up for this. Originally set at 22 sq ft / 22 gallons, changing this line to a different number affects drag, top speed, and downforce. The worst shared line is the frontal area / fuel line. The third thing to watch for is shared lines. The only place where feel can benefit is in the tire section and that is only referencing the real thing, like simulating a drifting car. NR2003 is based on simulation, not NASCAR Heat: NR2003 Edition. If you are changing random lines thinking it will improve your work, you are basing your EXE on feel or want. The second thing to watch for is what to edit.
