Spec V-240 brake swap

[cosmo]

I'm sure we've all heard that the 04' Spec V has the option for 12" Brembos with 4 piston calipers. And I've noticed that the new Spec V's are also 4 lug. Brake swap anyone? The only thing is I don't know what bolt pattern it is.

[bob marley]

I am going to try this once I finish my curent project. I am going to order 1 front caliper and rotor (unless I get another rotor somewhere else). I believe 1 caliper is about $300. However, I think the rear might not work unless you get an e-brake drum like on the 300zx because I think the rear pistons might be different (like on the 240sx) but I could be wrong. Anyways, it doesn't really matter because I don't think you can get them from nissan yet.

front is a 4 piston caliper w/ 12" rotorrear is a 2 piston caliper w/ 10.9" rotor

So they are a 4x114.3 bolt pattern?

I only care about the fronts anyway

[nlzmo400r]

the fronts of hte spec V is the only ones that have brembo calipers, and yes they are 4x114.3, however, the new brembos WILL NOT fit under the stock 24o rims, so you'll need new wheels as well

[Exar-Kun]

why not save yourself the testing efforts(and possible waste of money) and get the 300ZX brakes?-chet

[nlzmo400r]

cause everyone else has those, and besides, i think he just wants the gold caliper that says brembo

[cosmo]

however, the new brembos WILL NOT fit under the stock 24o rims, so you'll need new wheels as well

I know, I 've got that worked out already

And these have 1" more surface area=more swept area=better braking performance. The calipers weren't a factor. I just wanted some bigger rotors than 11"(Z32)

[nlzmo400r]

its hard to believe a lil car like the spec V has bigger rotors than an older 3oozx, and the calipers are the same ones off of the 35oZ as well, however the rear brakes on teh spec V are from the maxima

[bob marley]

You know I gotta have those gold calipers that say brembo in red to go with my gold wheels on my blue car (scooby style ).

I hadn't made my mind up yet, I was just considering this an option to that of the z32.

Johann

[nlzmo400r]

the Z32 brakes are on many 24o's, however you'd be one of the first around with spec V/z33 brakes on a 24o

[Dori Dori]

Yeah, because it works and works well.

Who cares how many others have it...it's not an aesthetic mod (well, at least it's not supposed to be but apparently you all are getting all googly-eyed over these calipers b/c they say brembo and are gold). If the z brakes can stop a heavy *** z well, they'll be more than adequate for 99% of you guys. I can understand if these brembos were cheaper or easier to get but...

Gezzz....:rolleyes . It was just a joke. I was just considering these as an option.

[nlzmo400r]

im sure the z33 brakes would work just as well, if not better, than the z32s, since they can stop a heavy *** z33(which is heavier than the z32 btw) they'd be perfect, actually, another brake swap i always wanted to see done, was the brakes from the 3oooGT to the 24o, the 3oooGT turbo's brakes were huge, and very strong (as the car weighed about 37oo lbs or slightly more) and they stopped about as fast as the old z32's, so those would also be very good for a swap, a lil more complicated of course, but not much

The Z33 weighs more than a Z32? Hardly. Z32-3474Z33-3188

Plus the Z33 are 5 lug which would require a conversion($$$ I don't have or want to spend) and would require at least 17" wheels. (I'm going 16")

And the 3kgt brakes have been done before. But it has the same issues(for me) as the Z33 brakes

Ease up killer...he never dissed the Z32 brakes....he just wants something different. NOTHING wrong with that. If he's got the money to spend, let him spend it. He's not ricing his car out or doing something stupid to it. Absolutely no reason to criticize him for wanting his entire car to look good. You going to tell me I should sell my 13.1" Brembo kit and go to Z brakes?

[nlzmo400r]

thanks for seeing my point cnichols, also the z33 weighs 3318lbs (and thats for the track model) and the 199o 3oozx weighs 3221lbs and the 96 turbo weighs 3481lbs, so i stand corrected

[ale89se]

so should 16's fit or will 17's be needed? just got some 16's but if i need 17's for this then oh well!

[nlzmo400r]

well, honestly, the only way to figure that out is a test fit, 16s will be VERY close, hell the stock spec Vs 17s are close, so give it a shot and see, personally i dont think 16's will work, u wont have enough room for the caliper is what would be your problem

Don't instigate. All I was saying is basically the same thing that Exar was saying...the Z's work (well)/fit (well)/are easy to come by (very)/are safe (if done properly); so why not save yourself the time, effort, and money (and keep yourselves from being in a potentially dangerous situation) and go with them? It was nothing more than advice. And yes, you should sell your Brembo kit. To me. For cheap.

PS - Please refrain from calling me your pet names. Thank you.:fruit

[nlzmo400r]

the reason people know the Z32 brakes fit well and work well, and are safe, is because someone had to be the first to try them, so whats saying the z33 or spec V brakes wont work better or be safer than the z32 brakes on the 24o?

[Dori Dori]

Custom brake lines for the swap were devoloped for safety issues. You want to make custom lines, be my guest. All plays into the headache factor you don't have to deal with when doing a z32 brake swap. Hell, even having to think about it makes it more difficult and not worth it to me. Guess I'm just uber-lazy about this b/c of my previous points about the z32 brakes (that they work...really well and I seriously doubt anyone with them has major braking issues). It's like my papi used to say; if it aint broke...heh, you get it.

i see your point, i guess we're at a stalemate, and also, i know the old saying ,but even for that, your stock 24o brakes werent broke, you fixed them

[Exar-Kun]

anyone know how thick the SPec-V brakes are?I would wager that the Z brakes provide more heat dissipation than anyone needs here(exceptions being road racers, like dori...) if you want to use your money to get "brembo" calipers on your car, just call brembo, give them make/model and bolt pattern, and for 1600, they'll MAKE you a kit...and it'll be far better than the spec-V brakes, I assure you.-chet

[cosmo]

What size rotors or do you decide that?

[Exar-Kun]

typically, you can specify either a 12.5(or close) or a 13.1"...and ferrari F40/F50 calipers, etc.

I would order the 13.1" front and a matching 12" rear with the F40 system(6 piston front, 4 rear) and two peice rotors, about 3k probalby to custom make.-chet

I've heard of a bracket that allows you to mate up Z32 calipers to 3000GT rotors. Any more info to this(a few searches here and on google didn't turn up anything useful).

The Z32 rotors are overkill for the street, but on the track I can't see them being much more than adequate. Let me put it this way, my 12.4", 38mm front rotors got well over 1000*F on a summer day with me(a novice driver) and street tires just casually extending my braking zones. My car weighs more, but I can't see a high horsepower 240SX being all that much easier on the braking system to allow probably a half the thermal capacity and get by.

In my opinion, you can NEVER have too much brake for your car. Go tell the guys in their 2900# Porsche GT3's that their 15" rotors are overkill.

[nlzmo400r]

i feel the same way, you can never have too big of brakes, thats why i want 2o's on my altima, i figure that way, i can have some 17'' rotors for my car!!, see, its all for performance

[Exar-Kun]

"In my opinion, you can NEVER have too much brake for your car. Go tell the guys in their 2900# Porsche GT3's that their 15" rotors are overkill"

they are. bigger brakes do not stop you better. if you can lock up your tires, you have all the braking force you need. for track use, things are a bit different, as the brakes need to be efficient at dissipating heat. BUt I know guys running Z32 brakes all around with slotted rotors and racing fuild and nice pads, and it holds up great..far more than adequate, esspecially for a car weighing 800lbs less than a twin turbo Z.

for hard track days, sure, the brembo system will pay off in spades because of its fade resistance(especially on short burst courses, for long periods of time) but I digress...thats a whole nother class of modification. 95% of the 240 owners wont need that kind of heat-resistant/dissipating braking system EVER, nor anything close to it.

-chetnlzmo: I sincerly hope that was sarcasm....i assume it was.

[nlzmo400r]

of coures it was, but if i did have 2o's, id def get 17'' rotors for the hell of it

[Def]

Sorry, guess I should have been more clear - I was talking about track use.

The simple fact is that even the stock system is MORE than adequate for 80-90% of the drivers here that just use their car on the street. Just get slightly better pads and call it a day.

Track use is a whole 'nother animal all together. You need all the thermal capacity you can get when you are going to hammer the brakes harder than anyone on the street ever thought of doing for 25 minutes straight.

Weight is important when stopping a car, but keep in mind that the equation for kinetic energy(which is converted to thermal energy) has mass as a first order term, and velocity as a second order term. So reducing the mass helps, but if you consequently are allowed to increase your velocities, then you might have problems. That's why it probably won't be "easy" for Z32 brakes once you start making some decent power on a 240SX(upwards of 250rwhp).

BTW - bigger brakes DO stop you better, even if you are able to lock up a tire. It has to do with being able to achieve higher braking torques at lower line pressures. Which, assuming you have ABS - will help you brake more when on an "off" cycle. I understand where you're coming from by saying they're frivolous for more people, but there are tangible benefits for larger brakes under almost all circumstances. Yet again, the cost of that improvement(if you aren't using the increased heat capacity) is prohibitive if you are only using your car on the street.
