Algodoo

nice colors, it is not common to see purple on phun
the suspension (hydros) seem very similar to my lowrider's except yours got higher
the shock absorbing part of the suspension is still "squishy" so it is quite unrealistic
currently i am making all around views of my custom gt car v.2 (some with suspension, such as the front view)
and i am making another basic project that i wont reveal yet

I gotta inspired by your low rider, but I don't checked your suspension
I tried a lot of combinations: the actual, a piston-moved hidros, a hidraulic hidro (with water, but have much lag) and a rotating hidros (a gear spin fast and hit the suspension, causing a very high bounce; but, after some bounces, the suspension wreck)

Oh, a susgestion to your GT car: you can make a movable truck, and a track, would be cool

hmmm i may add a truck, but i have to finish with te views and then i will see
