Math for determining needed brake size

[Apogee]

Anything over 14" is typically overkill IMO unless you're talking carbon/ceramic. The truth is that a lot of guys with pro-touring builds could probably get away with less brake the majority of the time which could help performance in other regards such as acceleration, unsprung weight, etc. That said, there is a balancing act in selecting brakes that will work on a multi-purpose vehicle that needs to perform well both on the street and at the track with minimal fuss in between when the time comes, and that's where the "pro-touring" form meets function IMHO. As noted above, pad compound (CoF) and temperature range will in large part determine driveability and overall performance as well.

You didn't specify which kits you were considering purchasing, only rotor diameters...are we to assume the same thickness rotors? Same calipers? Same pads? Typically you do get what you pay for in my experience, at least relatively speaking, so that $1000 difference probably accounts for those differences. If you care to share which kits you're considering, you may get more real world response from folks with similar builds, at least in terms of performance.
