It looks like the kits save ~25 lbs of unsprung weight on the front alone. That's pretty sweet...

I have weights for some BBK's when I was researching them. I lost the wilwood specs but they were the lightest I found.
Stock Akebono: Front caliper: 11lbs Front rotor: 29lbs Rear caliper: 6lbs Rear rotor: NA Alliance BBK: 8 piston caliper: 6.50lbs 6 piston caliper: 5.95lbs 14" rear rotor: 21.75lbs 15" front rotor: 21.00lbs AP Racing: Front 6 piston caliper: 7.3 lbs Rotor weight, assembled: 20.3 lbs Rear 4 piston caliper: 4.7 lbs Rotor weight, assembled: 22.8 lbs Stoptech BBK: Front 6 piston Calipers: 8.5lbs Front 380x32mm rotors with hats mounted: 21lbs Rear 4 piston calipers: 8lbs Rear 355x32mm rotors with hats mounted: 19lbs |

The only concern I had over the AP are the dust boots used on the front calipers (the CP7041 caliper). Under extreme heat these dust boots have been known to get cooked, but that was in a different car. I'm confident that it should hold up well under HPDE driving. There is the more heavy duty CP5555 caliper but that would add significant cost to the kit. |

every dust boot will cook under extreme use. Even though I track heavily (80% of my miles are track miles) I went with the front brembo upgrade because in addition to my desires, I also have a budget, plus the APs wouldn't fit my wheels.
The brembos do the job.

Are you sure it wouldn't fit? You have an angle grinder don't you j/k The kit fits most 18" wheels, yours must bit a little thicker than most. |

AP kit is next. Full Brembo GT set is above AP. Mike: 80% of your miles are on track? Does that include driving there and back? You must live close to the track and not use your car for anything else... or am I missing a joke.

Imag, rep coming for a great thread !
AP Racing, Brembo, Stillen (and fine Vivid 'Racing' too!) - great contributions and I have to say thanks for fact-based debate and sharing some hard data Not sure I can add much to this discussion other than these few points: - I've been running the AP Racing BBK front and rear for a few months and I couldn't be happier... no more fade, great pedal feel, improved control, full confidence - Stillen has been over the top ready to support this kit and has some great technical staff standing by to help you dial it in and select the right pads etc - the overall price really wasn't that bad - install is a snap and as may have been mentioned you should be able to get some bucks for your stock kit... my personal viewpoint is that brakes is the last place to 'go cheap' - please don't base your decision on a few hundred bucks of price difference - here's a link to my original review a few months back if you haven't seen it AP Racing Big Brake Kit Installed!

We have 4 cars between two of us, plus I'm on call for the airline and they don't call me, and for my other job I work from home, so I really don't use the Z for anything but track days right now, plus maybe the occassional run out to lunch or something

I agree that cheap really shouldn't be one of the criteria, but if you can get a deal on what is known to be a quality kit then that is a different story.
Both the Brembo GT and the AP Racing appear to be quality kits, but ultimately the decision came down to the fact that I could run 18" wheels with the AP but couldn't with the Brembo GT (although you could with just the Brembo front caliper upgrade as Mike did). |
