Fast brakes offers their rear disk kit with 11" rotors, what size are the rotors on the t1r?

Also, which one do you guys think is better?

 

I prefer the 9" rotors in back; even tho' the FastBrakes have a small pad to reduce force I need to experiment to see if that does reduce rear braking effort to not overcome fronts. Sort of like braking only rear brakes on a bike. When you stop real hard it may get you into trouble. Thats the word here from our NASCAR brake gurus anyway. They're working with a computer program. We'll see.
Right now the AJ Racing unit looks closest to our 91 CRX rear discs. We were going to machine spindle brackets to match our spare units but we're holding off. Don't want to lose those spares. And since we are selling the CRX I'd like to include them with the spares.

 

I got front and rears from Fastbrakes but haven't been able to put them on yet. I sent them out for powder coating. Brian was really great to deal with. He needed a little extra time to put the rear set together for me.
