370Z Sport Brakes FTW - Pics

[ken in az]

So I got one heluva good deal on some calipers off a 370Z sport edition. They are the exact same as the G37 sport BBK that we've all been talking about.

Here's the pics - keep in mind I really like the color of the stock 370Z caliper - but for my look I'm going with Color matched calipers - to match the pearl white of my car....then have a nice set of Black gloss spoked wheels to set them off.

Here's the pics - Calipers - Rotors - Stainless Lines and Fluid

Very nice looking. Those actually look like my rotors that I bought, except mine is the oposite. Instead of 2 rows of holes for every 1 slot, I have 2 slots for every 1 row of holes. I have that black coating on the rotors where the pads dont touch still though. They look really sexy on the car

[ken in az]

How do you like the new brakes - did you do a write up and I missed it?

And I was wondering on the black coating. They are E-Coated which is a fancy way of painting them so I wondered how long it would last. Good to hear - thanks!

ok so let me get this straight: 370Z calipers and rotors will bolt up directly to our M without modifications?

[Backdoc7]

Sweet!

Yea Ken was going back and forth with me about that.The Akebono sport brakes from a G37 sport should fit no problem on any M with 19" wheels, as the Spindle and hub are the same part on the M and G.Akebono front brake system part numbers are as follows:Calipers(L/R): 41001-JL02A / 41011-JL02ARotors:40206-JL00APads: D1060-JL00B or D1060-JL050 for the high performance R-spec pads

Rear system:Calipers(L/R): 44001-JL02A and 44011-JL02ARotors: 43206-JL00APads:D4060-JL00A or D4060-JN00A for the R-spec padsYou also need to buy the brake pad hardware kits part Numbers D1080-JL00A and rear D4080-JL00A

Depending on what the Dealer charges in your area, (they may discount it for purchasing everything) You're looking at $1800-$2200 or so. If Someone were to buy it from me, I'd discount it to $1500 for everything...

Yeah, the 370Z sport rotors and calipers are 99.9% identical with the only differences between the two are "color" and the fact that the 370Z uses a hard line with a double wall flared fitting at the caliper rather than the G37sport Banjo bolt.

Good new about that is that #1 who cares about color and actually I like each equally. #2 The 370Z can use the banjo bolts at the caliper just the same as the G37.

Concept Z Performance has the entire kit for $1450 and another site I've seen has the entire kit for $1350 but can't remember who it was.

You can contact infinitipartsusa.com and talk to justin and he will get you squared away.

Rotors - 100% exactly the samre between the two 370Z and G37

Oh and Poysinous, I was talking about the X models specifically in the other thread I had already known these fit on the 2nd gen M.

Only think I'm a little fuzzy on is if the sport rims need a 20mm spacer or a 25mm spacer - which I have both so we'll see. Also, I hear that the non sport wheels - even though they are 18's will still fit the larger calipers and rotors with a spacer but no one has been able to confirm this.

[ken in az]

Oh and Poysinous - awesome call out on the part numbers!

I checked wholesale costs locally and could just barely get to the same cost of the Concept Z kit. I have no Idea how they can price it that low - we'll actually I do know "how" but don't know why they chose too.

Again, is braking actually improved significantly?

I'm doing one of these early next week and I can post a few pics once its done. I only learned of this recently and actually saw this done on an 05 G coupe today and it looked pretty good. I think I would look better on the M though.

That's why you were asking about doing that today, I was wondering where that came from.

To take it one step farther I am curious if the master cylinder and brake lines could be upgraded as well. Sort of a Stage II setup. At least steel lines. That is what I am curious to see.Since they use the same knuckle and basic frame mounting location I wonder if the parts would fit maybe with some slight adjustment.

Hey Gabe I'm assuming we don't stock steel brake lines do we? So let me get this straight. The 06+ M uses the same spindle as the G37/370 but not the same one as the old Gs? Interesting. You are a fountain of cross reference knowledge.

Again, is braking actually improved significantly?

It should but I didn't really buy the setup for improved braking. I have put 20K miles on the car which had no rotor/brake problem when I bought it and now if I hit the brakes at over 60mph the steering wheel shakes near out of my hands. I don't brake hard and of all my cars including nissans that have had even smaller diameter rotors I have never had a warping problem.

I don't think you can improve much as far as braking power since these are 12.6" rotors and 2 piston calipers to begin with. I have hit these brakes in panic situations and they perform well. But when you look at the sheer size difference it's hard to imagine it doesn't improve upon stock.

What I am after is to remove the warping of the rotor. These new rotors are huge and I have no doubt that they'd be up to the task. I have seen others getting the frozen rotors and having success, but those rotors are expensive compared to these. Stock replacements that cost $82 front and $70 rear - now thats a deal!

I have to admit that I did get them for the cool factor too, mostly the cross drilled and slotted, but I also did that to reduce the weigt as well. These suckers weigh in at 29lbs so they are 6lbs heavier per wheel front and just a little heavier rear. I have yet to weigh the calipers so maybe we'll save some there since the stockers are made of iron.

I'll weigh them out and see

Sweet, I agree and that'd be awesome to get some shots!

I think it's cool that the X models can do this as well as I had no idea they had the same equipment.

Stainless lines for the M are the same for the G37 as the G35 as the 350z as the 370z when using the Akebono BBK. The 370Z uses the hard line to the caliper but when upgrading to stainless lines you would use the banjo fitting at the caliper instead of the hard line.

Per FSMMaster cylinder on the M = 1" Master cylinder on the G37 = 15/16" Master cylinder on the 370Z = 1"

So I think we are good on the Master cylinder.

As for fitment - it is direct bolt on no adjusting necessary.

You should also see if the upper A arms and rear camber arms are shared between the G37 coupe - sedan, the 370Z, and the M

[fiveliterbeater]

wow this is amazing that it doesnt take a whole lot of trouble-shooting to try and figure out what after market brake system to buy. i cant wait for some pics : )

[SteveTheTech]

Thanks for looking up the details. I was thinking the apply pressure might be different but then again the M is heavier.

[Poyzinous]

Those are definitely different. The cars have different subframes and suspension because they differ in ride height and suspension travel, as well as track width.

[sean@z1]

those things are massive in person nice upgrade

[CompleteCustoms]

I have to say... I'm excited about this, and perfect timing, I need new brakes.

[ken in az]

Dang - they look near identical though.

Here's a pic of the M front a arm



And here's a shot of the G35/G37 Arms aftermarket



Something to note is that the SPC camber correction kit for the G37 actually uses the G35 sedan 07-08 spec arm with a G37 style ball joint.Got all info from this thread - http://myg37.com/forums/brakes....htmlI think it's possible that it'd work. Hell the brakes do and nissan is notorious for utilizing the same components from car to car - or at least components that'll interchange easily.
