- I had a quick look around and apparently the mod uses the Cup-physics, one of the four that ship with NR2003.
It would then be interesting to know whether the tracks they use over at Delta have optimized grip-levels.
The mod does use the Cup physics but the tracks have been modified to make them as close to 1964 as I can get them.
You may ask, "Why 1964 when the mod is 1963??"
The hobby stock mod came out before the GN63 mod. Nunya and Ace, 2 long time Delta members, were working on creating 1960s cars for one of the bodies that came with that mod. At the same time, I was working on tracks to get them to 1960s speeds and I found that I could get most to 1964 speeds by using Cup physics, the restrictor plate and by tweaking the setup to use 1963 Galaxie gearing, weight bias and no tape. And a little less than optimal tire pressures.
Black Widow/Northwest Racing started development on the GN63 mod and so we somewhat abandoned the Hobby Stock mod 1960s project and joined the GN63 team with me just doing tracks and testing.
So, while the mod does use Cup physics, the car is 3600# and with chassis 1 (restrictor plate), the car puts out close to 400 HP. The 1963 NASCAR rule book says the cars must weigh the shipping weight and the 1963 Ford Galaxie shipping weight is 3600# and while it had more than 400 HP, the aero of the car in game and lower HP balance each other out for the most part. Again, not being able to change the physics, I went with what was the closest I could (like the GNS with the 55 mod, or the CTS physics and chassis 5 for the GN69ST mod, but those or other stories).
The tracks for use with the GN63 mod use chassis 1 (plate) to keep the HP down and the redline being at 7200 RPMs, but displaying as 6200 is pretty close as well.
If you take the car to a standard N03 track, it will act like a 2003 NASCAR stock car, but if you take the car to the GN60s tracks, you will be running 1964ish lap times. Especially if you use the fixed (gn63) setup we run in the league and that is provided with the tracks (note - not all tracks are completely finished as I write this, still working on some).
Another way to slow the cars to mid 60s speeds is to run lower air pressure than optimal. You will notice the middle of the tires are usually 1 degree F less than the outsides and this not only slows the cars but also helps the car grip the lowered grip on the GN60s tracks.
Now, while I just explained what I've done in my attempt to make the cars feel like your driving in the mid 60s, the best way, IMO, is to not know about the changes and just drive!! So, instead of sharing this info with a friend that might be interested, do me a favour?? Point somebody to the mod and take them to the Delta server which is currently hosting Daytona with the fixed, gn63 setup. They might think the physics have been altered because of how the car drives.. A blind test, so to speak. Since we know what's been done to try to get the cars to turn 1964 lap times, we are tainted and might have it in the back of our minds, "I'm driving a 2003 Cup car with a restrictor plate, no tape, lousy weight distribution and under inflated tires". Get that out of your mind heading into T1 or you will be into the railing!

Season starts at this track on Wednesday. If you like it and would like to join, you are welcome. If you don't like it, I tried my best. If you think you can improve the experience in any way, please let me know. I am always looking for people that can help work on things.
Note - Some objects at the track are from the 'shared' folder and I don't like when somebody overwrites my 'shared' stuff so I didn't include the old looking things I've placed in my 'shared' folder that replace the modern looking TSOs.
If you want a blimp that isn't modern, put this one in your 'shared' folder - http://www.deltasimracing.com/Files/Tracks/Ziggy/blimp.zip
