What does a full front and rear kit cost with everything, lines, pads, calipers, 2 piece rotors, etc?
My main issue with any 'brake upgrade' is once you go and mess with the pistons, the number of them, their sizes, your master cylinder etc. you throw everything off unless it was sized for your chassis correctly. Brake bias and ABS will not function 100% like it is supposed to. Unless you have a stand alone ABS controller to dial it in:

"at STOPTECH all brake upgrade kits are designed with the characteristics of the original braking system taken into account to minimize these differences. This is the reason that when you order a STOPTECH big rotor upgrade kit the
new caliper bores may actually be smaller than the units you are replacing to "balance the equation." This is just one way in which our engineers attempt to retain the original system's P-T and P-V integrity. Sure, it's not one-size-fits-all, but neither is your car…or your driving style. Why should you expect any less from your brake upgrade?"
You can buy a correctly designed BBK used for $2500-3k on the e9X that will be brand name StopTech, Brembo, etc. not DICK ASS. Normally they are 6k.
Also, who wants to put their life in the hands of a DICKASS
When you die they can write on your tombstone: Died from DICK ASS.
Would you ride on DICKASS tires? I just can't imagine putting my life in the hands of such a dumb fucking name.
I totally understand the concern here - both with messing with brake bias and with using a brand name like 'dickass.' My justifications may be different than others, but that's what makes modifying cars so much fun. I would never run a single turbo because it destroys the whole concept of the twin turbo inline 6. Different strokes for different folks, right?
Anywho, with regards to brake bias "problems" - is it real? Sure. Is it overblown? I believe so.
Now, if I were using rando designed brake kit, sure I could see a massive issue. Since these are pretty much a copy of AP Racing (they offer calipers based off of the Brembo as well), it should have similar bias characteristics. AP Racing claims there is little to no bias change when using their kits, front only or both, so I took that as enough assurance that bias wouldn't be an issue. Plus, I guarantee you the only people that think about brake bias on a regular basis are tracking their car competitively and then they also take into consideration the pad - because pad differences front to back can change bias. If you have swapped your front pads only to a different type, you have affected bias. I even considered running sintered metal pads for the rear, but was afraid it would bias the rear too much. I don't track the car, this was as much a "bling" mod as it was maintenance.
Pricing - this is where things get interesting.
Right now, I think a front kit is around $1,500 shipped, but I think if you emailed them directly it would be cheaper. I bought mine 3 years ago ish before they were even on Aliexpress and the Grand Tour had never heard of dickass. I hate even saying what I paid for them because instantly people thing they must be made of aluminum foil and dirt.
I received:
2 x 9040 APRacing "pad compatible" calipers
2 x front pads
2 x 355mm 2 piece aluminum hat rotors
2 x stainless steel brake lines
Nice pretty "APRacing" style box for each caliper and rotor
Box that said "goodman" on the lines
Price before shipping: $558
Shipping via DHL: $265
Paypal fee: $42
Total: $865
Overall, I am very pleased. The only issue I would say is that the paint on them isn't the greatest and has some chipping after 3 years, but really, who cars. I've not had any leaks or issues and I have STRESS TESTED these. My car isn't the fastest thing in the world, but its ok - traps ~ 128 - 130. I've done a multitude of drag strip passes and slowing quick, lots of hard slows from 130+ (back roads in Mexico of course).
I was just as apprehensive as everyone else would be regarding using a brake kit a. that cheap, and b. from China. But guess what - all your pads and rotor replacements are from China and no one cares. Ok, ok, if you say you use Zimmerman rotors made in Germany, just leave because the thread is about DICKASS brakes, not where can I overpay for some rotors. Even Textar is made in China now.
Performance:
No, I did not and will not do any "stopping distance" comparisons because that is an invalid metric to measure a BBK. All that measures is your tires. These are more for brake fade resistance and I've not had any issues with fade or warping since purchased. I'm still on the stock pads that came with them so I'll do a follow up once I check the pad condition. I'll get some pics of them currently as well, but here are a few I have from when I installed them.
