something handy (maybe) for our openwheeler fans released for GTL and GTR2 today...

Cooper T73 project was a scratch build initial test mod, designed directly for GT Legends game by SimBin, to check if is yet possible to create and drive satisfactorily an opewheeler car add-on at historic touring car simulator. All the mod work experience has been transformed into F1 LEGENDS RACING mod.

Although it is a single car add-on, the mod pack also includes few non Cooper manufacturer related skins in different racing team colors. To fake better the full grid F1 1964 race feeling, the team cars use different wheel mesh and engine pipe styles / engine covers, but all the cars use same physics and sound set.
