Looking for some input about the 300zx bbk. I am considering doing this upgrade to the front of my maxima. Anyone who has done this I've got a question for you...
How's the nose dive of the car under hard braking? Because you've added 6 pistons to the front of the braking equation, is the car biased towards the front? What's the braking preformance really like? Should I do this or just grab some zinc coated slotted and x-drilled rotors and call it a day?

As Always, thanks for the input.

 

^ i have a friend with the bbk... it's insane stopping power it seriously like throws you foward on intense braking. I personally think that no one could possibly brake that hard even on normal conditions. it seriously made my eyes pop out of my head when i first felt it 0_0. Do it. The BBK is worth its money.

 

there is more brake dive but it only comes up when you are showing off to others and doing panic stops, under normal driving conditions you don’t notice it. Make sure you get good pads but plan to use them up pretty quick, i think i got like 6k out of my last set. But that was because I would speed up to 100mph before an off-tamp to see what the brakes can do, they stopped every time with no brake fade.

 

You probably rode in Peter's car, which has a hacked together brake upgrade. The calipers are larger, but the rotors are smaller. That braking is nothing compared to the high quality kits available. Those will literally pull the tears out of your eyes, especially from 140 down to 60!

 

Which one does Peter's car have? You mean the 300z on the 300z rotors?

The Cobra 13" rotor / 300z caliper BBK should give anyone PLENTY of stopping power up front. Do the rears and the brakes are incredible. Nice thing about the 3 gens is the rear bbk is cake.

 

yeah I need to do the bbk as 107 +mph traping in the 1/4 is not fun stoping with 3rd brakes. I would do it if I was you and had the extra cheese

 

is this a conversion for the 300zx rotors or are they direct fit in place of stock also what calipers do u haffa use the 300zx or will i have to get a different calpier

 

i give you guys some input also. i am currently building the bbk for my max. i am going to be suing 13 inch cobra rotors and 300zx tt alluminum calipers. so far i am in the price range of about $300 for calipers $105 for all 4 lines $75 for hawk hps pads for the front and $60 for brackets and rings. so that brings me up to a total of $540 and i still need to get rotors. for the rotors i am thinking of getting bears but do you guys think its worth getting 2 piece rotors?

 

300z calipers and milled 300z rotors..

 

If he has 17s or larger, he should just buy my brackets/rings and a set of cobra rotors. Nice upgrade that he would definately feel

 

my bad here is the link for the bear cobra rotors.

I am waiting on stock from a Canadian distributor for the Baer 2pc rotors myself. They are pricey as hell and you can't re-surface them. Serious bling here but if you want to cut down on adding rotating mass to the front wheels, it's an option. I run heavy wheels so I'm trying to prevent adding any more mass. If I had lighter wheels I wouldn't get them.

 

how much are they from your distibutor?

 

$449USD. They are Canadian so I don't pay brokerage.

 

For everyone who doesn't know, they don't fit on stock rims without spacers.

 

just took mine off, actually...the stoppage is insane, great kit for the price...my rotors were around $40 each from napa, just regular ole blank cobra rotors...no need for that fancy $500 crap here.

get it!

 

why did you remove your kit? for me its not about being fancy but moe about performance. and i do know they dont fit under stock 17 oem rims but they do fit under stock 18 oem wheels.

 

to sell them...getting ready to trade my car in, and plus it's getting winter time and time to put the stock 15 inches back on, which obviously i cannot do with the bbk on

but about the rotors...i just cannot see paying such rediculous amounts of money for those kind of fancy rotors, while my napa blanks are probably going to be within what, 2% of the performance those expensive ones might add? the weight i can understand, but if i was going to be such a weight **** there are lots of other places to remove it that are much cheaper/free.

 

Well if you're going to spend, spend BIG

 

 

You gotta pay to play.
IMO, the kit with Cobra rotors is shady because the relocation brakes for the 300zx calipers are flimsy. The calipers weren't made for that size rotor anyways!

 

flimsy? care to provide details? the brackets i took off my car after a year of use wern't bent, broken or warped, so how exactly are they "flimsy?"

 

i think he is just saying that its a put together bbk instead of a bbk like his.

 

i'm aware what he's trying to imply, i simply want details to back up the **** talking.

i really wish there was a way to test the braking difference between my $600 kit and his $2000 kit...i'm sure he'd be crying all the way home.

 

i seen doubleog's maxima when he was getting is "bbk" installed, and i saw the bracket and caliper flex when the rotor was turning. That should not happen.

 

Thanks for all the input everyone. I think that because I'm living north of the 49th (I get snow and winter) I'm gonna stay away from the 300zx caliper upgrade. It just occured to me that if I go that route, I'm gonna have to get new winter rims and new summer rims. add that to the price and things get outta hand in a hurry. Of course I could probally sell the stock rims, but who's gonna want to pay shipping on those???? NOT ME. I'm really leaning towards some technafit braided stainless steel lines and maybe some hawk pads and some slotted/drilled rotors.
Again thanks for the input...
Do I really need 8 pistons stopping the car... Nope
Would it be hella cool... Yup
Would I be the only one in Canada? I think so...
Can I afford to dish out for 2 new sets of rims? Hella no.

 

If you gonna stay stock size, I highly recommend Brembo blanks paired with Porterfield RS4 pads pushed by ATE Super Blue brake fluid.

 

why the blanks? I like the look of the slotted/drilled rotors and can they be re-surfaced?
Either way, I don't want that rusty rotor syndrome our cars are so famous for.
thanks

 

It's possible but not recommended.

 

were do u get the relocation bracket ?? for the 300zx calipers

 

Flimsy? How can 3/8" thick steel be flimsy?? More T-E-T bs. I've run this all day, every day 365 days a year. Absolutely no problems.

 

The brackets and rings are from me. http://forums.maxima.org/showthread.php?t=430799

 

it has occured to me that if top element saw the caliper moving/flexing as he turned the disc, is the disc true?

 

I simply posted about what I saw with my own eyes. It was a brand new cobra rotor, so it should be straight. No wobbling when spinning, but when the brakes were pressed the bracket twisted and made the caliper move. This is with the car in the air, so i can't imagine on the road with more load on it.
3/8" steel is not all that stiff, and the dogbone design is what makes it flex. I'm not bashing anything, and it probably isn't noticable when driving. The ears on the caliper for the mounting bolts were made to connect directly to the hub, so if the caliper is spaced out it needs to be a super stiff mount.

 

It's plenty stiff. I've been driving on it for many many miles. the 300sx turbo guys that have a similar kit avail also have not reported ANY problems whatsoever. And many have been tracking this setup up for years (as some maxima owners have here).
