I have an ECS Tuning big brake kit,, it stops great - but I have two issues.

Can anyone tell me if a more affordable replacement rotor is out there other than ECS?

The rear brakes look silly in comparison. I know there is not much benefit to rear upgrade but I would like the look of the matching read Porsche Cayenne caliper and an 11 or 12 inch rotor.

Has anyone done a mod like this??

 

I am not trying to be a party foul, but why do you need a big brake kit? Most times than not, it will make your car go slower.
