lightened flywheel Q&A

I have a 91 n/t manual rx7. I have ordered a Tein suspention for it and am installing a rear cage and mounts for my Sparco. I use the car for club days out here in Portland,Or. The road course here in town is PIR. The same one used by CART in June every year. I am looking for a lightened flywheel/clutch and was curious what you guys thought of different options, and or if anyone had a used one they wanted to get rid of. Anyone? Anyone?![COLOR=navy]
