I recently purchased and installed a 12.2" Fastbrakes BBK. I believe I ordered his last 12.2" kit but he has some other kits for the Maxima:
http://fastbrakes.com/shop/index.php?cPath=30_82

The kit was around $800 and came with Wilwood Superlite calipers, 12.2" 2-piece rotors (Colemen I believe?), Hawk HPS pads and braided brake lines. The Wizard helped me install the BBK a few weekends ago. We also did a full brake fluid flush with Valvoline Syn Power.

The rotors came in my choice of solid, drilled and/or slotted. I have no real reason for choosing drilled other than the slight weight reduction and, of course, looks.

I'm more into drag racing than I am autocrossing so my main reason for doing this conversion was for weight reduction. Reason 1 = weight reduction, reson 2 = increased brake performance, reason 3 = aesthetics. Following are the respective weights, BBK vs. OEM:

BBK:
- Rotor (with hat and bolts) = 12.4 lb
- Wilwood Superlite caliper = 4.9 lb
- BBK Hawk HPS pads (1 pair) = 2.2 lb
- Caliper bracket (w/ all bolts and washers) = 1.0 lb
- Braided brake line (forgot to weigh so I am using a conservative guess) = 0.3 lb

OEM:
- Rotor (actually an OEM size Brembo blank) = 15.0 lb
- Caliper (with rubber brake line attached) = 9.4 lb
- Pads (Actually OEM size Hawlk HPS, pair) = 1.6 lb
- Caliper bolts = 0.2 lb

Total weight savings, per wheel = 5.4 lb, of which 2.6 lb is rotational weight savings.

Additional information: Kosei 17" K1 TS wheels = 13.7 lb and with 235/45 Proxes 4s = 36 lb 14.6 oz

I can tell no difference, performance or feel, between OEM and the BBK.

Nice, but absolutely no noticeable differences between those and stock brakes?

Also, you think these fit under 16" wheels (even if that was the last one)?

 

Wilwood FTW!

Can I get some pics of your entire car? I was looking at those rims for their weight and would like to see them on a 4th gen instead of just the Tirerack image.

 

say what??? How can that possibly be? Have you bedded the pads in sufficiently?

 

with a properly designed brake system, you shouldn't notice any difference until you take the car to the track and start beating on it. I've got the 13" version that I made myself using the same calipers and Fastbrakes hats--- so the only difference is the rotor size.. suffice it to say that I can outbrake just about anything less than a true Supercar on the road course.

 

I would think the lighter weight (unsprung weight reduction) by itself would make a difference in feel - lighter steering, less "crash" over bumps, etc.

I notice the difference in this regard clearly whenever I swap the 2-pc rotors for the OEMs....

 

yeah, but keep in mind he's going from a 4gen so the rotors are much smaller than the 6th gens you're used to using.
the weight difference is much less.

he's saving unsprung rotating weight, yes.. but he's also going to a larger rotor and all the weight is on the outer perimeter of it instead of the hub area, so the moment of inertia is probably not a whole lot different than stock. that makes the required acceleration and braking forces nearly the same as with the stock rotors. BUT he'll get the handling benefits (less crash over bumps, better steering & cornering response, etc) of losing the weight.

 

I'll vouch for that, my eyes nearly popped off its sockets when Matt slammed on the brakes when he last demonstrated it. My first response was, "I need more seatbelt!". What's even better is his car hardly nosedived!

 

Yes, I agree with Matt93 100%. I didn't expect to notice any difference on daily driving. I was actually hoping for no difference. I was a little fearful that the brakes would be too touchy and/or the pedal would feel harder. But nope, daily driving is the same as stock. I agree with Matt that the difference is apparent after repeated braking (ex. autocrossing). Granted, I have not yet slammed the brakes/panic stop - but, again, I would suspect the tires and anti-lock brakes would kick in and contribute to the stopping performance more so than the bigger brakes.

MorpheusZero: This would probably clear a 16" wheel in the radial direction, but I seriously doubt that they would clear on the perpendicular direction. My rims are only 7" wide but they have a spoke design very conducive to BBK fitment. And even my rims just miss the caliper by 1/8"!

MOHFpro90: I don't have a full pic. right now, sorry. I'll try to get around to taking one (but that means washing the car, taking the pic, uploading to Photobucket, linking, etc., etc. It might not be any time soon, sorry).

irish44j: Yes sir, brakes bedded just fine.

 

I currently have 8.5" +35 wheels off of the rear of a Z32TT, transverse clearance should probably be alright--what's the offset of those superleggeras?

I'm not sure if I'd rather just do this or get some lighter 17x9s and get a ~13" BBK. Either way it's good to know that the option is (or was) there.

I'm also in for some pictures of the full car, you don't need to wash it.

 

I think you're thinking of this ol' thread.....

http://forums.maxima.org/showthread....ghlight=offset

Chunger has 18x8's with 35 offset, Superleggeras, and they clear his AP BBK.

Mine are 17x8 with 40 offset, Ultraleggeras. My rims clear the Brembo Gran Turismo BBK by about 1/4". Oh, FWIW, my BBK just clears radially by about 1/4" as well.

 

pics ??????????????

 

D'oh, they're K1 TS... I didn't look at the pics at that point, just from my recollection they were superleggeras guess I got him mixed up with Chunger.

In for pics as well, I assume your brembos come with 13" rotors?

 

why a 12"2 rotor though?

 

I guess you mean 12.2"? I know - it is a tad small. 1.) It was the last one he had so he sold me an already nicely priced $1,000 kit for $800. 2.) I already told you my main intention was weight reduction. 3.) I thought I could 'get away with it' since I 'only' have 17" wheels.

 

Why not a 12.2" BBK?
If you're going for performance, the 12.2" will do everything a 12.6" or 13" kit will do. They can/do use the same calipers, and the 12.2" x 1.25" rotor is a standard size from the Coleman Racing- the guys who make the Fastbrakes rotors as well as for my kits. Fastbrakes orders an off-the-shelf race rotor. I have my 12.6" rotors custom made by them to fit 6th gen Max rotor.

It's also just about the biggest thing you'll be able to fit inside a 16" wheel. that's why they're 12.2". the only reason anyone wants bigger is for bragging rights.

 

Pics to follow. I will probably start a new thread with pics and info so I don't ***** up Ptatohed's thread.

Yes, they are 2 piece 13" rotors.

 

dang dude i was just asking.

thansk for the explanation though....

 

Dang dude I was just telling. you asked, I explained.

 

haha. I was so impressed with just putting Axxis Ultimates on my car. I guess i need to step up to some bigger rotters.
Hey Matt when u coming to Dallas to chill and drink. PM me.

 

Hmmmm, I wonder if you'd notice a difference during usual braking if you had solid rotors instead of cross-drilled rotors. I've always believed that cross-drilling really just removes contact patch between the rotor and pad, so even if you had a larger rotor and larger pad, the surface area is still no bigger than an OEM area. Just a thought.

 

It does, and you're right, but the bottom line is that it won't make too noticeable a difference. My guess is that when he starts beating on his brakes he'll notice something.

 

Oh my gosh. I am dieing over here.

 

Hop on in. We'll have a brake orgy.

 

That's a valid point. The BBK pads are a lot bigger than OEM and the holes aren't that large so I'd like to think the pad/rotor contact area is larger (and of course moved out radially) but you're right. From a strictly-performance point of view, I'm sure solid is better.

 

the surface area lost from the drilling doesn't change much, it anything at all.

brake torque is strictly a function of clamping force and the pad's coefficient of friction. use the same compound of pad with a smaller surface area and you'll still get the same braking abilities.

the big difference you're going to see is the reduced pad life from the additional heat produced and the cheese-grater effect of the drilled holes.

Matt... did you ever take a ride in my car when I had good tires on it? heheh

dunno next time I'll be in Dallas... I'm headed to florida for a week starting Monday. OH... I haven't sent back the RSVP yet, but count us in for 2 spots.

 

wow man thats a nice setup. those are what i call REAL calipers. be happy that you dont feel any different under regular driving. with the z32, i usually avoid getting on them too hard because its not very comfortable due to bias. do you like yours better or james's ??

 

One question here - how do you get replacement "hawk hps" pads for these calipers...

 

I'm not following you. I would just order the Hawk HPS pads that fit my new BBK. Right?

 

He's really asking where I believe...... You can get the Hawk hps pads for the Wilwoods from Fastbrakes for starters. Wilwood also carries and sells all sorts of pads for these calipers.

 

That's crazy money for brakes. It better stop on a dime.

 

i beg to differ. thats dirt cheap for a TRUE bbk. kits like AP racing and brembo run for 1900 & 2500

 

Apparently you haven't shopped big brake kits. I beg to differ. I was almost hesitant to order because the price was so cheap.

 

..lol jk

soo these bbk you got are pertty good compared to AP racing and Brembro??

 

Right... I've been thinking about getting/building this kit for myself so i wanted to learn as much as i could before i get into this.. so there is a dozen of different original wilwood pads (actually, only 2 for street use - bp10 and bp20 if i remember correctly), but... according to wilwood there is no hawk pads made for these calipers. How come.....

 

The Hawk HPS pads for the Wilwood Superlite caliper is Hawk Part #HB521F.800.

That's what my superlites came with.

punch the part # into google and you'll find tons of places that sell them.

Here's one: http://www.frozenrotors.com/store/HB521F.800


EDIT: I forgot you were asking about the Brembos. Check HAWK's site, I'm sure they make a pad for Brembos too if they make them for Wilwoods.

 

You won't find information about someone else's pads from looking at the caliper manufacturer's websites. you have to look at the site for the particular pad manufacturer.. (Why would they want to tell you the competition makes something too?)

Hawk, Raybestos, Ferodo, Porterfield, Cobalt Friction, Carbotech, EBC, Performance Friction, et al ALL sell pads that will fit Wilwood, Brembo, AP, etc calipers. you just have to know where to look.

here's a nice huge file to look at that will open your eyes to a lot of things..

I am running the same wilwood(fastbrakes) kit on my 4th gen maxima. I'm curious if this kit would be compatible with Matt's rear BBK kit? I would really like to complete the set.

 

If you have the 1.75" pistons in your BBK then it'll work great. If you have the smaller pistons, then you'll need to install some brake bias adjusters.
