'94-03 Rear Brake Upgrade option...12.3"
 

Head on over to www.fastbrakes.com and take a look at the 12" Upgrade Big Brake Kit for the '94-03 Maximas. <--kit no longer sold online, call Brian for details

http://s6.postimage.org/p4mk4b0j1/Fa..._rear_12_2.jpg

I called Fastbrakes (602-323-2110) and spoke to Brian regarding the kit. The relocation kit comes with a bracket, to relocate the stock caliper so you can still use the stock parking brake without issue, and a 12.3" rotor whereas a stock '03 Maxima rotor is 10.9" :eek:

The kit on fastbrakes.com is $300+shipping but if you call you can get a blank rotor for $50 less from Brian.

:cool:...this rear BBK kit would go great with the Dual Piston G35 front calipers and 12.6" rotors! (thanks Aackshun!)

Hello more even brake bias!...and hello CHEAP BBK option! Total kit is costing me ~$500. :D:D

My braking mods = complete.

:faint:

So that kit = relocation bracket and rotors?

What vehicle are those rotors from?

Good find.

Per Brian at Fastbrakes: The rotors are from Hondas...the center is modified by 4mm to accept the Nissan size.

Good find. :D

So, for verification (for some weird reason, fastbakes.com is blocked at my work) it's a relocale bracket and rotors?

100% correct...can you view the pic above in my original post? It is only the 12.3" rotor and caliper relocation bracket.

If the site is down you can call Brian directly...602-323-2110...I did this mainly to inquire about a less 'fancy' rotor option since there isn't one listed on the website.

Blocked at mine too, was just gonna ask you guys about this...

Wait. You guys are typing www.fastbrakes.com, right?...like with an 'r'? Lol just making sure.

ORDER PLACED!!!!!!!!!!

Would be great to see a kit installed. I've been wanting to balance out my AP kit for some time. Brian Hasty from FB was very helpful when we did the GB for the first(?) Wilwood Superlite BBK way back with 12.2" rotors.

As soon as I get it and have some free time I'll be installing with pics.

Might have to take a day off from my normal job just to get the time. lol

Thanks for sharing the great info Jeff. Dummy question, since we will be using the same stock calipers and pads... the catch is the pads will be covering the extra 1.9'?

Heat dissipation (better fade resistance) and better braking torque/force are the main benefits of larger rotors.

...unless you're into aesthetics as well then it's a nice thing to go from 10.9" to 12.3". lol

It's not a surface upgrade, it's the size of the rotor, you need a minor lesson in braking school..... See below actually :lol:

:sprint:

:highfive::ben:

Writing this from my phone but are the rear rotors still not vented?

Stock caliper allows for a 0.35" (8.9mm) thick rotor. A vented rotor in that width would increase the chances of rotor warp.

At least with a 1.4" larger diameter the heat can dissipate better...paired with some good pads and this is still a worthy upgrade.

(I ordered some AXXIS ULT pads to go on my setup in the rear and Deluxe going on the 12.6" fronts...I don't track but my main goal was to get a better brake bias than with 'just' a front BBK)

Ahh... I knew that. :o :D Make sure you take lots of picture when you install them!

I should have some pics as well. I placed my order and should have them installed in a couple of weeks if everything goes as planned.

I spoke to Brian on Monday and he said the kit should be shipped 'soon'. I hate getting antsy for mods.

bump any updates

Bump; subscribed and interested...any updates/pics?

For some reason my job has a filter for that site:gotme:

Too bad I'm not going BBK, this would be perfect.

In for the results :)

Can you please advise if the "05" and up 350z dual piston caliper will bolt up to my 5.5gen like the 6thgen caliper/rotor. What would I need (if anything) to make this work? It looks like this is your setup and I'd like to do this as well. Thanks in advance.

^^^Never mind...just read your write-up:D. These are going on with the 12" rears soon. I will report back with findings...:cool:

I was waiting to update that thread till I was done with the G35 calipers but here goes:

The calipers are not a direct bolt-on if mated with a 12.6" rotor. The holes line up just fine on the 5th gen knuckle, no problem there, but there is just a little bit of scraping from the rotor to the inside of the caliper. Just like the 6th gen caliper setup, you either have to mill the 12.6" rotor down or you can do what I'm in the process of doing and mill down the surface area of the caliper itself. They're iron so milling down 3mm from the caliper shouldn't be an issue.

The G35 dual-piston calipers are definitely an upgrade over the 6th gen setup anyway...just not as direct of a bolt-on than we hoped.

(copying this over to that thread as well)

Waiting for the final results as well. Actually if it is a legit part I will order this rear kit ASAP. As I need more rear brake bias using the front BBK and don't want to spend a small fortune getting a used rear 300ZX BBK.

have you thought about getting a proportioning valve?

it reduces the brake fluid pressure to the rear brakes. (which help prevent seized/brake lock-up)

Wow...I went straight to ebay and Car-part to scout out the brembo calipers...Just when you thought someone had thought of every "rice" thing to add to your car you see something like this:

http://www.ebay.com/itm/BREMBO-LOOK-...ht_5833wt_1032

LMAO

I see those all the time in my searches. I usually end up filtering my ebay searches with "-cover". So stupid.

The fronts always lock up first. The rear brakes need more bias hence the need for some bigger rotors and/or more aggresive brake pads. Also putting in a proportioning valve is a pain, its alot easier said then done.

:laugh: at the fake Brembos. Though in all fairness most people who run these BBKs never see any track time. Might as well fake it and save the $$$ if your never going to use them for their intended purpose.

THIS.OMG.THIS.

Track time, no. Spirited driving? Yup.

Got a call from Fastbrakes and my order is being shipped today!! Cant wait!!

:cool:

I will give them a call sometime this week.

Small Write-up
 

Before I get into the write-up I just wanted to warn that this kit can take closer to 2 weeks between when you order and when the kit ships. I believe Brian is a one-man operation and he has to take the Honda 12.3" rotor to a machine shop to have the hub grinded wider to accept Nissan's hubs.

During the whole process Brian has been very easy to deal with and I consider him to be honest and knowledgeable with what he says. Easy to communicate with...just a little slow. lol

Also the instructions provided are written instructions only. There really isn't much 'know-how' needed to install these if you're familiar with brakes already. Some DIYers are more used to fancy pictures like NWP provides.

My write-up is a bit short on the process because I mainly feel like if you are getting this kit then you're most likely mechanically-inclined enough to figure the process out. It really isn't that hard, 4 bolts that need turning for the brakes to come off. Hardest part is the parking brake.

Now, onto the fun:

Ok so I finally got around to 're'installing my set last night. I originally received the kit 2 weeks ago which included:
Brackets, assorted washers, new bolts and 12.3" rotors. :cool:

Got everything installed but noticed one fault. The caliper didn't match up with the full face of the rotor, causing around 5mm of pad overhang. Ugh
So I emailed Brian at Fastbrakes and he said the problem was because he thought I had the older rear rotors (4th gen?) which were smaller and thus less distance for the torque bracket to actually fit, causing the pad overhang. No issue, he said he would order new torque brackets for me and send them out.

Fast forward to last weekend and I received the new torque brackets.

Looked different so I was hesitant to try installing without calling Brian…I started installing anyway.
The issue I ran into was the new bracket has a small lip where the pad guiding brackets normally sit.

Just a little grinding and we’re good to go!

Bolted everything back and set out to bed in the brakes properly. As of last night/right now, I am on stock front brakes so my driving impressions are more clearly geared to what the rear upgrade has accomplished. I can tell the rear brakes are biased over the fronts right now, which is inevitable running my stock fronts. I was able to lock up the rears pretty easily whereas in the past I mainly felt the fronts doing all the work. I know it’s only my ‘impression’ of how the brakes feel now but I can definitely tell the rears are much stronger.

I should be installing some new (larger) fronts tonight but that’s for another thread.
