Ok. I have gone through extensive measuring and knocked up a hub with FSVT rotor and built a bracket to offset the stock bracket.
I stand corrected a second time....sort of.
It will only fit with selected grinding of the mounting ears and with a reduction in the bolt diameter. Then it is very tight. I would not feel safe doing this even though the grinding that must be done is radially outward and perpendicular to the bolt holes. Am I right in assuming the forces are tangential? Well it would work but then if the monting ear ever developed a crack I'd be in a world of hurt. So I have scrapped the deal and ordered the fsvt calipers.
Ok, shifting gears now. What is required to protect the brake bias between front and rear with regard to changing rotor size?
I'm guessing if you move the fronts out a certain distance then the rears should also be increased.
The Increase in the front area going to fsvt rotors is about 16.4% or a 7% increase in diameter.
Lets assume you want to balance the brake bias, wouldn't you also want around the same increase in the rear brakes?

I wouldn't bother with trying to adjust the bias. YOu're calculation of the "increase" is too basic. You need to integrate the pad area over the distance away from the center of the hub to be more accurate. At the end of the day it still doesn't matter. My rear brake could be paper plates for all I care as they're there for the ride (AFAIC), and to hold the car from rolling when I apply the parking brake.

I figured it was very simplistic. Thats why I'm asking here if someone knows the answer. Just moving the pads outward gives a better leverage advantage so shouldn't that increase braking effect?
Well, there's always the looks factor, actually that is the most important factor to these questions. The factory rears look way too small anyway and probably look worse now with the Focus hardware going on.
So even if it doesn't help, I want to fix them for cosmetic reasons.

Understood. If cosmetics is calling the shots, I gues syou can get the wilwood rear kit that's out there.

Then it would look odd having a cast & machined caliper.

Hence why I say leave the rears alone!

This is exactly some of what I was talking about yesterday Tom. Save your information, data, and protoypes. I stopped giving new information out a long time ago. Let the others blindly walk in circles. That's all they want to do anyway.

Sometimes it sorta seems that way. I was just fishing a little to see if I could educate myself.
