Available Open Source Meowmobiles

Made with the love and randomness of a cat.
I drive with no assists except Automatic shifting. I do use simulated steering on a controller.
Everything is Open Source along with an excel spreadsheet. ( ask and I might still have it )
Meow be with you.

Quick Tune
Tires: F 29.0 | R 29.0
Final Drive: Dink with this if you want. Move it up and down and find the sweet spot that gives the fastest 0-100 time.
Camber: F -2.5 | R -2.5
Toe: F 0.0 | R 0.0
Caster: 5.7
Anti-roll bars: 40 * ( 1 - 0.62 ) = F 15.2 | R 15.2 (These will always be 15.2 )
Springs: Find the upper spring rate, 100% stiff. For example if it is 1218 then: 1218 * 0.62 = F 755 | R 755
Ride Height: If the car is uneven, even it out as close to 4.1 inches high. If your car can’t get as low as 4.1 inches, then 1 click from bottom.
Rebound:
RWD: F 5.1 | R 5.0
FWD or AWD: F 5.0 | R 5.1
Bump:
RWD: F 3.1 | R 3.0
FWD or AWD: F 3.0 | R 3.1
Aero: Full if you got it and want to stick to the road. Full front and no Rear if you want a bit more speed at the cost of grip.
Brake: 48%; Pressure: Whatever you want. I like to stop fast, so I use 150% to 200%.
Differential:
RWD: Ra 25 | Rd 10
FWD: Fa 80 | Fd 20
AWD: Fa 30 | Fd 0 | Ra 60 | Rd 17 | S 60

Meow !

Im going to give the GTO a try. I have a tune for it myself that i use on Silverstone in the lobbies but maybe ill learn a thing or two from the tuning gurus.

Cheers

I hope it works out for you.

Awesome work ‘Spot’! I have my own RSX and decided to build a separate tune based on your build and found it quite satisfying. The only difference I did after testing was bump the rear camber to 1.8 and I used ONR’s tire calculation to find an ideal tire pressure. Also, good work on the Excel build sheet. Really appreciated it and would like to see this more often. I’m curious, how and why did you come up with such a low ARB for a B class bruiser? The other tune for my RSX is a C class lobby runner and my ARB’s are 20.4 front and 16.4 rear.

I’ll have to take a look at the math, it is all right there in the excel file. 2007 or later is needed.
Ah yes, I have learned much about ARBs since this build. They might change if I was to re-tune and drive, but so would the springs, damping and aero. All that stuff is intertwined.
I’ve learned a lot about cars, physics and math in the past 2 months that everything was and is evolving, so I might do things a bit different now.
I let my meowchanics do their work, but I still drive it many laps on all tracks; and scratch up the leather a bit,
