Max brake pad thickness for 2014 TA1 0

[sharmut]

Before I pull the rotors off to take measurements, wondering if anyone knew whether the 2014 TA Brembo Calipers would accommodate a 18mm(includes backing plate) thick brake pad, assuming rotor thickness at 32mm?

Trying to find alternate replacements to the Brembo TA "wide annulus" rotors. One option is to use AP-Racing's j-hook rotors, but requires a shorter pad size due to hat diameter being larger. The dimensions of the Raybestos R1001 are 131.6mm X 77.3mm. The R780 at 131.6mm X 67.1mm would work with the AP rotors, but are normally 18mm thick, unless special order the R780A at 15mm. Do not know the math behind the braking difference with having a shorter pad (-10.2mm) in clamping force and coefficient. Perhaps the lighter AP rotors can help make up some of that delta.
Also wondering if the 18mm thickness matters in terms of how the brakes felt on-track, do you loose firmness and modulation.

The replacement cost is significantly less for the AP j-hook rotors, readily available, plus can be ordered burnished. If they perform equally and last 14 track days, equalling the OE Brembos, it' win at less than 2/3rd the cost(all-in).
