Growing up, my dad was friends with Bob Beasely, and I knew his son. I used to hang out in the garage (with his son) with his dad's Blue Iroc #8? I remember his dad would not run the fiberglass doors, claiming the weight savings was not worth the safety penalty, and that (jokingly) people discovered 911's handled okay, when you put wider and wider tires on it, they handled even better and better. So, it became a war of wider tires.

The flares he had on that thing were gigantic. Compared to my dad's 1966 911, all I can remember is how WIDE the iroc was. At the time, I think the flares were extended even wider with fiberglass than the stock version. Can't really remember.
Every time I saw the car, it was on jackstands, I think his son fired it up once when we were down there. Can't really remember. Mr. Beasley even came over to my house (at my dad's request) once to evaluate some scoring on a 944 engine I had. He stated "no big deal." Nice guy.
Beautiful car. IROC was a cool idea. That blue 911 was the bomb!
