It should not be looking huge, as you can keep the right proportions, if you take the same wheelbase as the 986 and it even looks better, the width is about 2 Inches wider, which is great for the mid inner metal support frame, the length in the back is oke and about 12 Inch shorter in the front, but if you take off the bumper and also the black grp bumper block...it fits perfectly.
This all considering the line and heigth of the door line and front wings. I will change the back wings into original 550 spyder ones, which are a bit more curved....love it !
More details like split window in the back, trunck, original round taillights,metal air intake, the Neumann Porsche 550 front with the larger side intake, classic style side louvres etc.
So no slight scale issues.....
