I'm guessing you mean the street car and not the LeMans car? There are a few diecast of that in various scales. There is a photoetch detail set for it also. It is very decent, but the front grille work is set more for the r8 v10. But all in all, a very nice addition for the kit. Not so easy to find tho.
