Caliper brackets are definately different, you will have to use the FSVT caliper brackets w/ the FSVT calipers.
Are you talking for non SVT's because, again, they bolted right up to Chris' car. And the wheels fit just fine too. And they are filled up quite nicely!
The only "issue" chris mentioned was that he heard the FSVT bolts are longet than the CSVT, so it's a good idea to change them anyway.
