Cluch and pressure plate help

Looking for something more hi-perf. When Mc Leod said they don't produce anything smaller than a 10-1/2" clutch they're missing out. Who makes performance clutches for all the rice grinders on the street now days. I'm
sure an Eclipse doesn't have room for a 10-1/2" clutch. And I'm sure they don't run stock clutches either. Mike
