Ahh I couldn't see the periscopo feature, but I guess the roof is masked off. Love the metallic colors on the CT, shows off the lines very well.
Sorry I missed that part of your question. Here is Brian's 'Rame Colorado Metalizzato' Countach LP400S. Image Unavailable, Please Login
Good observation. The square-shouldered Pirelli CN12s that the LP500 was originally fitted with made the fronts look extra-wide! Image Unavailable, Please Login
But later in the car's development, round-shouldered Michelin XWXs were fitted and they afforded more clearance and the fronts did not look so wide. Image Unavailable, Please Login
To answer your question, production cars got a set of narrower Campagnolos as illustrated here on the Prototype LP400 Image Unavailable, Please Login
