i have been waiting along time for these to become available but 9lb full magnesium wheels are here and they dont look like they're outta the 1950's apparantly weighingless then the rubber on the tires they promise 2-3hp at total gains for $150 each plus they look better then any CF rims ive seen in a long time
they just got released on the first and are only available in 17's

tell me what you think and is the weight removal really enough for 3hp gain?

Lighter rims will most definitely increase hp and fuel mileage, by how much i don't know . they look nice also..

What kind of finish is that, GunMetal? It would be nice if there were more finishes, like silver... Also, does it come in our bolt pattern? Isn't ours 5x114.3? All I saw on the site was:

192-77582 17x7.5 Magnesium 1400 +40mm 4x100mm/4x4.25 5.712 72.64mm
192-77584 17x7.5 Magnesium 1400 +40mm 4x100mm/4x4.5 5.712 72.64mm
192-77587 17x7.5 Magnesium 1400 +40mm 5x100/5x115 5.712 72.64mm
192-77588 17x7.5 Magnesium 1400 +40mm 5x110mm/5x4.5 5.712 72.64mm

Hmmm....
I do like the 6-spokes

150$ Magnesium wheels? This is definitely my next choice for wheels.

our bolt pattern is a 5x114.3mm(4.5"). that backspacing is a wee bit high, though. somebody should be able to poke their head in in a few minutes and comment better on it.
not too bad looking, either.

3g94MaxGXE

For $150 a piece that would be a steal IMO. The design is fairly nice but I'm into the BBS and G35 looks. Still 9lb rims for $600 total? Wow...what is the world coming to? XD

And to think I just bought new tires really bums me out

flirt with the dude behind the counter (put on some of your sister's jeans and talk with a lisp) and he might swap your new tires to the mags for free. unless you still are running sawblades like in your sig.... in which case.... get those mags and some new 17" rubber and send me your sawblades and tires!!

If you do a search for rotational mass, rotational inertia and unsprung weight, you can find some complicated formulas for figuring out the benefits of lighter wheels. That are a big benefit. If you have 17s right now, it will definitely be a noticeable gain. When I had my forged Centerline wheels (17x7, 13 lbs each) I noticed a difference. I never had them on a dyno, though.

17x7.5 with a +40 might not fit our cars without spacers, especially in the rear. My Centerlines were 17x7 +42 and they were very close to the rear struts. I added 5mm spacers to the rear just to give them a little breathing room.

Where did you find those for $150 each? I don't see a price on the website.

Also, does anyone know how resistant magnesium is to damage? I am curious as to why no one has been making this type of rim for such a long time.

sleepyvg30e

iTrader: (1)

to answer the age old question "if their so great why doesn't the manufacturer use them?"

the 9lb mags are now stock and standard on the new porsche carrera gt

CapedCadaver

iTrader: (8)

a) with that logic, then why modify the car at all? if any aftermarket mod is so great, why didn't Nissan install them at the factory?

a.1) costs. most drivers don't give a crap, so why install an expensive part or feature onto the car that most drivers will never notice or care about.

b) well no shyt! that's a PORSCHE CARRERA GT!!! 6-figure $UPERCAR. of course the owners will want super-high-performance wheels!!!

3g94MaxGXE

I'm new to the whole stock magnesium wheel thing but I do know they have been used in racing for a long time. Can't tell you how many years or anything but I've seen all kinds of cars with them. Especially 240SXs, drifters LOVE weight reduction.

How do you know the price? 150$ sounds awfully cheap for rims this light. The autocross guys are happy to have 12Lb autoX only 15" rims

holy shiate!
i think these are my next wheels.
will these fit the 4rth gen bolt patterns?

sciff5

iTrader: (1)

5x114.3 is equal to 5x4.5 so yes they should fit. Although I dont know what offset is good for a maxima.

I know they'll fit on my RX7 though and I'm psyched about that. I wonder how strong these things are. I would be nervous driving around new england with them on.

internetautomar

iTrader: (30)

All maximas from 89-current have the same bolt pattern.
89-94 take LESS offset than later models do.
in other words the 4,5,6,7th gens will fit these particular wheels better than the 3rd gen.

3g94MaxGXE

Magnesium is fairly strong. I've learned in school that it's like the lightest building material. This wikipedia entry should give you an idea of how strong it is.

so sleepvq, are you planning on getting these soon or what?

good news guys looks like the wheels already sold out and have to be remanufactured they will now cost $205 each and will be out soon

Maus

Wow.

if only.

G4nismo

iTrader: (9)

damn that was quick... still $205 for magnesium is a good bargain.

3g94MaxGXE

I agree, an additional $220 for a set is hardly anything.

1. too bad the width and offset suck.
2. don't use magnesium for the street. very light and strong, but brittle. they don't bend, they crack, and are unrepairable. lots of racers use them, but they throw them away after even minor wrecks or off-course excursions.

disposable wheels aren't worth saving 5lb each, IMO.

CapedCadaver

iTrader: (8)

hmm, never thought about #2 there.. what's your preferred streetable metal/alloy for rims?

mrkanda

iTrader: (3)

You would think they would try to at least recycle them.

sciff5

iTrader: (1)

20lbs total of rotational mass and unsprung weight is pretty significant.. and its only 20 lbs if you have some big dollar lightweight rims to begin with. Anyone on stock wheels will be cutting more like 45lbs off total.

Thats sick! But I agree.. not a street wheel.

MaximaN00b

MSRP on these wheels is $205 per wheel they are currently out of stock with no ETA.

i asked about them
but what Matt said made sense too me, and I believe i have heard before magnesium is strong but brittle..

and im sure they recycle them.. lol, Im a machinist, we dont just throw away scrap metal, especially expensive stuff like if it was inconel (strange **** to work on) or brass, even stainless scraps worth alot.

3g94MaxGXE

I was wondering about how brittle it was. One thing thats true of alot of stronger materials is they don't flex, in my machining class we were playing around with a piece of tungsten carbide I think it was and one of the guys who's been taking the class the longest pointed out that if we dropped it it would shatter, despite being the strongest manmade material in the world.

Carbon fiber isn't recommended for wheel use because of how brittle it is.

If you ask me aluminum would probably be the choice metal for wheels. The stuff is light, stronger per pound than steel and in machining it's considered harder to machine because it can have a little flex to it though I've never had a bad experience with it. Aluminum is also abundant on earth so it should be fairly cheap compared to fancy metals like magnesium.

MaximaN00b

definitely have to say aluminum is EASY to machine, since its so soft.. maybe for very TIGHT tolerances i could see it being alil tricky since its so soft.. but standard maching -+ .005 is simple.. milling its tricky cause its so soft, it will "clog" up a regular endmill, so a 2 flute or 3 flute, or a low helix is best as it will toss away the cut chips, and a slow speed too..

but yeah carbide is wicked strong/hard, but its true.. the stuff will just shatter.. ive seen it shatter MANY times..

Or theres some stuff we work with now called Flow-drilling, it looks like a "V" it spins fast, and it basically just.. melts metal and forms it. Its purpose is for thin material, say .125, and you wanna tap it with a 1/2 tap.. it'll melt and form a hole id guess a half inch deep.. very hard strong stuff whatever its made of, but it breaks like nothingggg.. and its expensive as hell, bosses dont like me when im breaking the bits i dont think. lol

Hmmm these look great, kindve like SSR Comp H. But i agree although the price is good i doubt theyll hold up to street use. The width isnt that great either, have the price of Buddy club QF's dropped at all?

* Doubt it.

The only people that will notice the weight difference is hardcore track junkies that have done much more to their cars than the typical bolt-on Maxima. otherwise there are so many other simple things you can do to make the car faster and handle better than going to fragile, lightweight wheels.

sleepyvg30e

iTrader: (1)

i just wanted too point out that the reason why these things are so popular now is because they have new ways of engineering the magnesium theres also a big difference between cast and forged magnesium which is what u may be thinking of when you say their brittle their designed to be strong otherwise this wouldn't be new because mag wheels are about as old as cars are the actual integrity compared to others like aluminum and cf.... i still cant find but as long as my wheels dont fall apart i dont care about lil scuffs and scrapes

also old mag wheels are banned from racetracks because if the tire pops they actually catch fire these wheels are not banned so whatever the difference is im still not sure but this is new technology not the same old wheels with a pretty face

3g94MaxGXE

yep as a powder magnesium makes a VERY hard to extinguish fire. Most fire extinguishers cover A, B and C fires. However magnesium is a D. I wish I could sound more educated in saying that but its been a few years since I learned about it (and about a million headbangs, slaps and other miscellaneous brain abuses later) but magnesium is EXTREMELY flammable, the only metal I can think of being worse would be thermite, which if you watch enough educational TV you may have seen the stuff get ignited and burn a hole through an engine block.

Either way, magnesium is like a grease fire on crack. If you are familiar with grease fires like I would hope most of you are putting water on them only makes them worse because the grease can float on top of it or whatever and I believe is hot enough to split it into hydrogen and oxygen - don't quote me on that one though. Magnesium however is easily hot enough to.

I was in my technical school's kitchen for a fundraiser (we were making hamburgers) and the grease caught fire and one of the Culinary Arts students who was there threw a pitcher of water on it and well it got worse (it wasn't that bad, everyone was calm and we all knew it could only last as long as the grease in the aluminum foil lined pan below the grill) and she got another pitcher and that time me and the other youngest guy in the class were like "NO! No more water!" it was quite funny cause she was in a cooking class and couldn't even deal with a grease fire when I could have done it when I was 7 and I still can't cook with anything but a propane grill or microwave.

Want to list some of those mods for an SE (the simple, go quicker, handle better, ones)?

Matt93SE

iTrader: (44)

I've posted mod lists around here before. mine is several pages long.
the jist of it is stiffer springs, shocks, chassis bracing, and wider tires. and put the porker on a diet.



Magnesium of any type- cast or forged will still do the same thing once it catches fire. it's EXTREMELY difficult to put out. because Magnesium + water = FIRE. It doesn't matter what form or manufacturing procedure it was done int, the compound still contains Magnesium, it's still going to be just as hard to put out if it catches fire.

And Magnesium wheels are not banned at race tracks. maybe the 30+yr old ""mag wheels" you find on classic muscle and used at drag strips, but they're alive and well on road courses using today's manufacturing techniques.

From the SCCA rulebook:

Shall I go on?


Nonetheless, magnesium wheels should never be used on the street. simply too brittle for DD use. not to mention the sizes posted suck for performance use. you need at least an 8" wide wheel for these cars.

go to the stickies about mod info. and in your vehicle profile specificy your year so we will always know if you have a VE or VG, since the SE (depending on year) came with either.

okay now when u say brittle do you mean its gonna get chipped really easily and look ugly and faded really quickly or does it mean the ****in wheels gonna crack in half, one day when im driving normally cuz as long as the wheels are retaining their integrity im fine with a little scatchin and fadin

heres a link with the wheel in our bolt pattern 5x114.3

heres an article i found about the benefits of mag wheels

NewsUSA) - Automotive enthusiasts can now upgrade their vehicles with high-performance, forged magnesium wheels adapted from Formula One racing designs.

Magnesium.com recently announced the introduction of one-piece, forged magnesium wheels for street use in North America. The wheels are 20 percent to 30 percent lighter than forged aluminum and offer increased safety and performance.

"The U.S. wheel market is quite formidable and we intend to supply a smaller but very important segment of the 100 million vehicle wheels used in North America," said Mark Lisnyansky, president of Magnesium.com.

The magnesium alloy wheels are initially available in 20-inch and 22-inch sizes, and are treated with a high-tech anti-corrosion coating. The company will also be developing wheels in various sizes and compositions for specific North American applications.

"Steel wheels are becoming nearly obsolete and the prevailing trend is toward cast aluminum wheels," Lisnyansky said. "While most people are not familiar with forged wheels, performance car enthusiasts know that forged wheels offer significant advantages. And forged magnesium wheels, which are lighter and much stronger than their aluminum counterparts, are the next logical step in optimizing vehicle performance."

Magnesium wheels offer consumers improved safety by shortening braking distances and delivering higher acceleration rates as well as improving gas mileage. The "dampening" factor of magnesium allows for vibrations caused by road imperfections to be absorbed six times more effectively.

Using specialized aviation industry equipment, the company has been producing Superbike and Formula One competition wheel forgings for many years. The wheels are forged in Russia by a subsidiary and then machined and finished in Italy.
