I was researching BBK's and only found dimensions and a generic picture for the Brembo GT kit, nothing you could print and cut out and hold up to your rim. I read they were easier to clear than the Stoptech kit, so I thought I'd see exactly how much easier.
First off, I'd like to say that I don't have first hand experience with either kit. That being said, here are the templates for both the Brembo GT kit and the Stoptech 328x28 kit (the 355 it is too big for me), directly from both manufacturer's websites...

Here's the dimension for the Brembo GT kit, with the fitment image turned 90 degress to match the Stoptech guide...


Here's the Stoptech guide...


So, Brembo's "A" dimension is from the mounting face on the rotor to the caliper face. Brembo's "A" is 38mm, and Stoptech's is 38.93... less than 1mm difference!

Brembo's "B" dimension is from centerline to Caliper inner surface. Brembo's "B" is 110mm, Stoptech is 114.3. Brembo is 4.3mm larger.

Brembo's "C" dimension is from centerline to Caliper outer surface. Brembo's "C" is 192mm, Stoptech is 188.93.. Brembo is 3mm larger.

Here are the two templates printed out then overlayed...




My conclusion is that the Brembo GT kit will save you about 1mm of spacer in most situations.

The Brembo fitment guide isn't as user friendly as the Stoptech one, so I made a user friendly version of it here for anyone who might find it useful...
