First grab the original model from racingsim. I've added a front grill that snaps in like a glove (insert by pushing / flexing the grill into place) ... a front intercooler ... and a display chassis with 1/10 scale wheel brackets for displaying.
Only the additional parts are included!!!
Model was heavily sanded, contouring putty applied/sanded and lots of airbrushing. Use hobby cement, loctite to tack parts in place, and filler where needed. Best to build the entire front end and back end first ... then join the 2 halves.
