General details:
– The STL file is set to scale 1/20. But you can build it in any size you want!
– Length ~230 mm.
– Wheelbase: 136,5 mm
– Model body is available as in two main pieces or in one if you want to print it in one piece.
– Rims are replicas of the original racing BBS-RE594 in smaller size.

– The wheels connecting to the chassis also with snap in pins and they can ROTATE!
– The original front grille has 10 grid each side.
(It is only with resin printer printable. With FDM only a 6 grid grille is printable.)
