I will only change the caliper if it:
-uses a common shaped pad
-has a larger friction surface area than OEM
-has taken brake torque, balance and heat into account

I have a lot of practical reasons to not want a BBK that I shan't bore you with, but neither am I looking to upgrade the caliper just for cosmetic purposes. I'm happy with the performance of track pads with the OEM setup and don't need the additional thermal capacity of a BBK as I don't tend to do more than 10-15mins of hard driving each time I go out on track. But I do like the benefits of a properly engineered fixed caliper over a sliding one.
