brembo caliper(evo) rotor? May need expert opinon

[Barlow]

So, I'm looking into doing the exo brembo swap and my 17" rims(aftermarket) won't clear them without very large(wider) wheel spacers, which I'm not really prepared to do. I should also note that my rims are brand new and would rather not replace them as I love the look of them. The spokes of the rims dip in toward the rim's lip to much to clear.

So my question is would anyone see an issue with running a 12.2" rotor(I believe the evo's are approx. 12.5)? I've seen calipers used on larger rotors then they originally designed for but of course never a smaller rotor - I guess it seems a little silly as to why someone would.

Whats the point of upgrading then? There is no logic behind any of this, run the wheel spacer, sell your wheels and buy ones where the brakes will fit, or don't run the brakes at all plain and simple.

Either get new wheels (wider preferably to fit the calipers) or sell your brakes.

BTW Im willing to take the brakes from you if you dont want to get rid of your wheels.

Just curious as to why you would not run a spacer? Also the position of the caliper does not change with the bracket kit it will always be in the same place so using a smaller rotor wouldn't really matter unless you can move the caliper closer which from what I know changes the geomtry of things a bit and could complicate braking issues.

Yes, I forgot to mention that I would be fabricating the brackets for the rotors.

As far as not being worth it, going from 2- pistons with a 10.8" rotor to 4-pistons with a 12.2" rotor - I thought would still be a great improvement and that's not included the rear.

I do realize more benefit would be made with a larger rotor.

The question still remains could a smaller dia. rotor be used without ill affect?

Also I have no issue running a small hubcentric spacer. but by appearance it looks like I would need a spacer quite thick to get the clearance i would need.
