With the Ride-tires the front width is indeed 195mm, 10mm more than a legal F104, the rear is 190,5.....only 0,5mm wider than a F104 with Ride-tires.
I'm currently working on a F104 front-conversion on the SP1 with the use of the upperarms and wheelhubs of the SP1. Unfortuanally the great steeringrack has to go to make the car ETS-legal.....
I will post a picture when it's done.
