Contour Enthusiasts Group Archives Forums Modifications Brakes ? Bracket allowing use of Focus SVT rotors ?

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?
