I am looking at a variety of options for my front brake upgrade and am curious if someone can provide me 'non-sales' information about why one caliper is superior to another. I have five calipers that I am looking at for the front of my '13 Boss running 305 square.
To my eye, the monoblock design looks to be primarily for strength to handle the added pistons (4 v. 6) but that cannot be the lone reason for the solid aluminum bridge across the top as the PP kits offer 6 pistons without. From a pad changing standpoint this appears to be a large negative for the XA5TO and GT350, but still learning, I am curious to know the performance advantages and disadvantages of each. The XA2E7 was the FRPP selection for the Boss 302S vehicles, but the XB105 appears to be identical short of the removable aluminum bridge. Again, was this for strength or were the pad c-clips not seating properly and this is extra security?
The performance kits are clearly hard anodized and likely have higher wearing internals that can better handle the heat generated in regular track use, but again, I am not certain. The OEM units are substantially cheaper than the motorsports versions, but is this due to the volume of production or significant technology improvements in the motorsports units?
EDIT based on JAJ feedback: These calipers all currently exist as kits for the S197 platform. The ease of the install and maintenance would vary widely for each
Thank you in advance for anyone able/willing to assist.
