Default 11 or 12" rear rotors?

Hi,
Doing an RS FastTrack chassis with an LSA/Magnum combo on a 66 Chevelle. I'm guessing weight will around the 3500 mark

As for brake bias would 14" front with 12" rotors be too much/little for this combo? My question is about the rears. 11" or 12" or do you suggest bigger?

12" will fill the open wheel area better.

The Baer 13" front and 12" rear brakes on my LSA '66 Chevelle are a good match. The prop valve on my Baer Remaster m/c is set to mid range to balance front/rear braklng. IMHO the 11" rear would be too small unless you're running small diameter wheels and can't fit 12" rotors.

12” rear rotors all the way.
For the proper appearance
Just use smaller calipers and a proportioning valve.
My two cents

I think the proportioning valve only controls when the rear wheels lock relative to the fronts, not actual braking bias.

Wut?

How could you control wheel lock without controlling bias with a passive mechanical system?


Here is what it looks like on a graph. https://wilhelmraceworks.com/blog/br...rtioning-valve
