370Z/370Gt Brakes Compared To S/r Chassis Brakes

[scandyflick]

Ive been looking into yet another brake upgrade recently (this will be my 3rd...) for my s14, and i stumbled across the nissan/akebono calipers that are fitted to 370Z and 370GT premium.

this is the best 'comparison' photo i could find, the other caliper is iirc a brembo (duh) turismo 6 pot.

as you can see, theyre fairly beefy motherf**kers. run a 355x32mm rotor standard.

my question is, will they mount up to an S14? or will i need some sort of adaptor made up? as im not entirely sure what the mounting spacing is for V and Z series cars. nor do i know if rotor offset will be an issue.

if they do bolt straight up, awesome! means a fairly substantial upgrade for under a grand.

cheers in advance,

The calipers are ok for a daily rig but not up to some good use, I remember somebody taking those brakes out on the track and on a stock v35/350z it absolutely cooked the seals. Replacement and performance pads and rotors would be hard to come across. And these brakes are very very heavy as well.

Compared to 4/2 pot brembos

Have only heard of one instance where the seals were cooked after track work. The brakes aren't that heavy, the rotors are but I think you can get two-piece rotors for them now (not much more than my 330mm ones anyway). I don't see why performance pads would be hard to come across as they are factory brakes for the 370z/g37, give it time and the project mu, endless, etc will have pads for them if not already.

Basically the same question got asked a week ago. It has been covered many times in the past.

Now since you are asking about the 370Z brakes that is different yet again. You will obviously need a custom caliper mounting bracket to move the caliper outwards to accomododate the larger rotor.

If you Google it there are plenty of threads on it because people always think they can get a cheap brake upgrade simply by stealing another cars brakes. 90% of the time it doesn't work like that and costs nearly just as much as buying a proper brake kit.

Not sure about the rears, but while the akebono fronts are larger and use a larger rotor, the actual pad area is smaller than a r33/r34/350z 4 pot brembo caliper.

That being said the Akebono calipers can be had VERY cheaply if you can get them to fit.

There is a kit offered by CZP for a 300ZX that apparently fits R-chassis and front S-chassis: http://www.conceptzperformance.com/Cart/description.php?II=3310&Car_Type=300&UID=2011020406134892.243.188.8 You can choose a kit with and without stoptech rotors or with no rotors at all, and buy rotors form your local supplier, which makes the kit somewhat cheaper. Browse their site. Good news is that massive 350x20mm rear rotor works with original parking brake (on Z- and R-chassis, that is).

But I dont see the point of adapting those akebonos to Silvia ar Skyline. They are impressively big, yes, but is it a good thing? I personally prefer the caliper to have variety of pad compounds available, have appropriately sized pistons to maintain adequate brake bias, be stiff enough and not to flex under braking, and be as small and light as possible unless it hurts their stiffness. Do akebonos have plenty of different pads easily available for them? Not really. Are they stiff and light? I dunno about stiffness, but they are not particularly light. Are they physically big and do they require big dia. wheels to fit? Yes and yes - more unsprung weight and more expensive tyres.

Plus they have axial mounts, so you'll have to use some dodgy adapters that aren't going to be extra stiff, nor will they be cheap or easy to fabricate.

It's the similar situation to the EVO/Sti brembos discussed on here for a long time: http://http://www.skylinesaustralia.com/forums/topic/203896-evo-brembos-on-a-r32-gtr/.

A substantial upgrade for under a grand will be a Merc or Audi rotor and spaced out factory sumitomo caliper. Same idea, but you won't have to spend money on calipers, just rotors and adapters.

UPDATE:

As for pad size, V36/Z34 pads

are quite a bit bigger than R33/34/Z33 brembo pads

and pads for sumitomo caliper

Yeah, yeah, I know, as laughable as it looks, disregard pic sizes, concentrate on pads sizes in mm shown on every pic.

Rear pads on 370z are bigger as well.

cheers for the help guys.

not as straight forward as i hoped it would be, ha, isnt that always the way?

no stress though, ill save myself some coin and get the wilall water cooling system instead, that should make the 33 gear im running a hell of a lot more reliable at mallala.

Great info and thanks for the links!

So, I gather that the Akebono calipers for more for show than actual track'ability. What can someone get if they're looking for a "NISSAN" badge but still great on the track? Basically, I intend to track my '89 GTR.

the offset of the 33+ rotors is to great. the disk will hit the lower arm on bump.(gtr) 25mm disk offset.
