In the FLOW-IMAGES galleries,there are some color shots of the VW Rabbit which Hucho,Jansen,and Emmelman were involved with.There is also an overhead ( plan view ) of the Rabbit nose in smoke.
You can see what little radius is required to prevent separation.
One of the SAE papers reported 80-mm in full-scale for leading edges.I think that translates to 4 and a fraction in inches.
But there is a formula,something like 0.03 X width = R.
