    I have been quietly working on this for quite some time and it is about time I present my work to the community.

    The mod is 90% done with just some tinkering and optimizations left.

    Enormous thanks to A3DR without whom this would be nothing more than some eye candy.

    Sounds are placeholder and will remain so unless someone would like to volunteer ;)

    At the moment I am focused on the Mach 1 with either the 351C or the 428CJ engines. There may be another surprise.

    3D modeling is a hobby of mine, there is no real schedule, but any news will be released here in relation to this vehicle.

    For those interested in a few pictures from the progress of modeling over the last year.

    Note:
    Due to some limitations of Assetto Corsa *cough* http://www.assettocorsa.net/forum/index.php?threads/live-axle-lateral-damping.47653/ *cough* the axle will experience intense oscillations if sufficient lateral impact occurs(like hitting some curbs while drifting) This is correct in the fact that the axles lateral spring rate is calculated appropriately, though without the dampening you will get some vibration both in the axle and occasionally in cockpit view.

    Out of curiousity, even though its the 1971 model in the article, did you make use of the aerodynamic data from October 1970 Sports Car Graphic?

    In case you don't have it:
    front lift: 320 lbs front lift @ 100 mph
    rear lift: 0 lbs rear lift @ 100 mph
    drag: 340 lbs @ 100 mph (includes tire drag)

    Love this car, had the pleasure to work on it and I can say it's already the best '70 Mustang available for any game out there.:cool:

    No, the 1971 is a complete redesign of the body so not confident on its aero application to the 1970 model, and those items that need polish, that is one of them, aerodynamics are a trouble to find good reference data.

    Ha, all I had to do was search a little bit more in my database, LOL... Sports Car Graphic, October 1969.

    1970 Ford Mustang Mach 1
    Front lift 350 lbs @ 100 mph
    Rear lift 75 lbs @ 100 mph
    Drag 340 lbs @ 100 mph (includes tire drag)

    Cool, thanks a lot, that will make this a whole lot easier, does that include the front and rear wings?

    Now you're going to make me dig out the magazine... and ... no wings in the pictures. No wings on the '71, either.

    Thanks, that really does help massively, it was the one place I had to guess.

    Hmm, something about the wheel/tires just looks funny to me. Not sure if it's the sidewall shape or overall radius but there just seems to be too much tire.

    eg. this challenger has the same wheel/tire setup and there's just visually less tire and more rim.
    http://board.moparts.org/ubbthreads/ubbthreads.php/ubb/download/Number/272592/filename/DSC_3458.JPG

    If I understand tire code right, F60-15 is 225mm wide tread, 135mm sidewall, and 380mm bead diameter. So the actual measurements would be a ~400mm lip on the wheel and 125mm of visible sidewall.

    That is a spectacularly beautiful model there. Very much looking forward to wrapping it around a tree in the (hopefully?) near future. :)

    @Stereo You know what happened? The mach 1 has 14 inch wheels, yet I used the Magnum 500 wheels and thus the F60-15 tires that accompanied them (as most people swapped to them and they look far better) yet retained the 14 inch wheel diameter. So yes you are correct, I will look into getting that fixed, great eye and thank you for that catch.
    @Ryno917 Yes, I hope to have a download as soon as the cockpit_LR is finished up and a few more edits and tweaks made(like said wheel/tire discrepancy).

    Always an eye opener to look back at the lift values on classic cars. I doubt there's much steering feel at 100mph.

    There's hardly any at 25...

    Try a 2000 VW Beetle... 332 lbs front lift @ 124 mph & 411 lbs rear lift @ 124 mph! It's definitely an outlier, though.

    Jelly mould shape never good for aero. See also mk 1 Audi TT, which combined healthy lift values with high sensitivity to body pitch so the balance of the car changed enormously under hard accel or hard braking.

    Anyway, we're OT aren't we...

    @aphidgod you are not incorrect, though at 25 its all due to the enormous squat that happens on any application of the throttle. That lift, if the tires actually hook up sends the nose up quite far, consequently increasing aerodynamic lift :p

    I'm not really a Mustang guy (see avatar) but if there is any old mustang to do it is this one. Looks great and can't wait to fight the bad Mustang handling ;)
