| fuck-up-the-braking-performance cat to be honest
You have to understand that manufacturers design the system to be slightly suboptimal in favor of front bias for stability under hard braking conditions for the typical nitwit consumer who doesnt really have good command of their vehicle
So if you drastically increase braking torque up front without doing anything in the rear, then you can expect, super stable braking in all conditions at the expense of every other measure of braking performance except pedal feel IF you manage to get huge front brakes that somehow retain the same total piston area as stock brakes...which is highly unlikely. This is easier to balance out to an extent though with a change in brake pads or just plain getting a similarly upsized rear brake kit that increases rear braking torque by a similar or equal amount as your fronts. Leaving out braking torque for a moment, you can also fuck up your braking system by using front calipers which have drastically more total piston area than stock and not upsizing the rears by the same amount. Your leg exerts pressure on the master cylinder which puts pressure on the fluid, which exerts pressure on the pistons, except now the pressure you exert is dispersed across a larger area up front and is unchanged in the rear. I'm no fluid dynamicist, and I cant find my physics charts, but if I had to guess what this means, it woul dbe that you press harder for the same amount of clamping force up front, meanwhile your rears are clamping much harder....not good for trail-braking I would think....or if you are trying to make evasive maneuvers in an emergency braking situation. That is my self-educated understanding of SOME of the implications of just replacing a purposefully designed system with a completely fallacious philosophy of "bigger is better". Most vendors worth their salt do their homework and when you read the phrase "designed for the Z32" it doesn't mean the hardware itself was manufactured specifically for our car. It SHOULD mean the vendor, out of all the calipers they sell of varying piston sizes, has selected the ones that retain closest piston area ratios for front/rear kits, or a front kit that is the closest that they offer to the original total piston area for front-only kits. Ultimately it is the Z owner's responsibility to double-check. This is why I like Wilwood, they publish ALL the specs for all their calipers on their website and you can be sure you know what you are getting into and put together the best kit possible from what they offer....which is what AZZC did. I am unaware of other vendors who do this but it has been YEARS since I last shopped brakes so hopefully this transparency is more common. Your best bet is to go with a brand that has a wide line of calipers so that you know you aren't getting a one-size-fits-none kit that preys on consumer ignorance. The best part is so many people fuck their brakes up and dont even realize it. 100% PLACEBO EFFECT. I saw some poor guy in Germany who spent $4k on a BBK for his STi and when we did high speed emergency braking drills for a HPD day out on the airfield, he found out his car was braking worse than VWs on stock brakes with aftermarket pads. He never even realized it until it was benchmarked. I guarantee you based on my experience with 99% of "car guys" that this is the case far FAR more often than not. We have the same stubborn ignorance here with a lot fo these completely un-thought-out frankensteined brake "kits" made from anything that looks bigger than stock. Great for parking lot and web forum heros...not so great for legit use.
