What ever happened to Girodisc Ultralites? I dont see them for sale any more? Didnt they also have a second option that was like superultralite? I know STM sells the Baer kit that they dyno tested for gaining some power, but I know the Giro's were lighter than the Baers are.

Are the Giro's still around?

I don't think they have done a run in a while but if there is enough interest shown, I am sure they would do another 10 sets or so.

What are you using the car for? The Girodisc ultralites are meant to be an autox/drag rotor only because of how thin the walls are. I wouldn't track on them or drive them on the street.

All I do is drive on the street. I also drag race with them. The past 2 years I have driven on the street hard, drag raced and attended 2 years of autoX at the shootout on them.
