Lookie what I found!

It looks like the Q45 brakes also swap, and might be a better choice for our cars. Apparently they have 25% more braking force, so they might not cause the rearward bias.

Any bias shift (in either direction) can cause a change in braking. Often, it's longer (not shorter) stopping distances.


If by performance you mean stopping distances, buy stickier tires and move on since the OEM brakes are capable of locking up with R compounds and decent pads.


The only functional reason (outside of feel) to run big brakes is if you need a larger heatsink for repeated high speed braking (ie track use with a fast enough car and driver to fade sintered pads) and to remove unsprung weight, but that's only a benefit IMO if you don't change something else negatively.


Plenty of other reasons for a BBK that are less functional, but you have to pick carefully to benefit. These reasons can include pad choice, pad expense, pad lifespan, rotor expense and rotor lifespan. I run different brakes up front partially for heat reasons when I was tracking the car often and for consumables cost. Pads last so much longer in my setup and are cheaper than the OEM size so over time it pays for itself - IF you track the car a lot.


Most people upgrade brakes for looks, which is fine, but it's worth mentioning that sometimes those upgrades are downgrades functionally...
