He's asking for the model number you use since there's eleventy billion different calipers.
You'd need 1.4" piston calipers to match the stock piston size. I'd assume 120-6805 for 1" rotor or 120-6806 for .810" rotor 120-6806 WILL work with standard corrado rotors. The difference is only .05". I confirmed it with wilwood tech support, and then found that KMAG is running it.

And those calipers fit?? (BTW that's an 18% reduction FWIW).
If so that would get rid of the need for a prop valve!
My concern about the FM prop valve solution is that while it may give you the right prop for the track on whatever tires you have, it may still be wrong in the wet. (I know, the solution would be to have a different setting wet vs dry) My 2000 has ABS and IMO the factory proportioning is pretty darn good from wet to dry.
Anyone have the 1.8 stock piston diameters?

Bah, it's 90% of the diameter, not 90% of the area. Sorry, I forgot to expand it out. My bad.
NB non sport front brakes are 2" diameter pistons. Should hold true for all standard 1.8 brakes. 1.6 brakes might be the same. Sport/MSM have a slightly larger piston.

Let's wet the roads down, now. With the OEM valve, you're still stuffing all that force to the front, but there's not as much weight transfer, which means not as much weight on the front tires, and suddenly they lock faster.
With the FM valve, you're sending more, which means as the rear tires do more of the work (in the rain, your rear tires do more work braking vs in the dry due to the lack of weight transfer). The FM valve would be BETTER than the OEM valve in the wet.
Race car drivers ADD rear bias in the rain.

i have the FM bias valve in my car and I've driven on the street in the wet and dry AND on the track in the wet and dry.
I set it up on the track in the dry a couple months ago because I finally got the tread worn off and had extreme grip. After the first session and 4 pit visits, the car was set up right. The car stops incredibly well, with enough rear bias that several people commented on how much the rear of the car wiggles on threshold braking. This car stops, and its easy to control in extreme trail braking...like 75-85mph through a triple-apex with a crest in the middle and off camber, downhill trail braking into a corner that tightens with an compromise exit.
Last weekend I drove in the rain on the track, and drove home in a light-shower, on slicks and had no danger issues either. Get the brake valve.

I also currently have sport brakes and they suck ***/kill pads in roughly 1.5 track events or 3 hours of track time. You really need multi-piston calipers if you're driving like a man.
