This is really cool!

Has anyone created a setup file for a USDM 2000-2003 S2000? If so can you post it or PM me? If not does anyone know the answer to the following items:

(1) S2000 frontal area?
(2) S2000 drag coeficient?
(3) Brake Balance %?
(4) G's of grip in slow corners (Anyone with data logging for a S2000 with race tires and with OEM stock tires). What we need is the maximum lateral G force achieved in a corner less than 50 MPH so aerodynamic lift does not effect the reading.
(5) Antirollbar stiffness front and rear in N/mm?
(6) Lift coefficient front and rear?
(7) Ride heights front and rear?
(8) Corner weights of car? RF, LF, RR, LR?

I just bought a used 2001 S2000. I want to use the simulation software to compare it and my Honda Civic with Type-R motor, suspension, and brakes. My Civic feels like it accelerates quicker then my S2000 and I want to see if it is fictional or actual (I could always take the cars to the drag strip but this way I can do acceleration runs without wearing out my cars ).

Thanks,
John

This is a low cost alternative to the Bosch software.

Why buy that program for $100 when you can do the same for free in the Bosch program? The Bosch program that you have to purchase has a ton more parameters that would probably not be useful for your average enthusiast.

The only thing this program has over the Bosch program is the ease of creating a new track. The only problem is that the program does not take into account track elevation or banking which can greatly effect a vehicles lap time. The Bosch program takes into account elevation and should produce a more accurate result. The problem with the Bosch program is that you need to have someone's PI data acquisition data from a lap at the track you want to simulate your vehicle on.
