Those G4's are cheap, but i think they look cheap. The calipers look small for an 8pot!? Dont you want a big caliper that will run a much bigger pad?

And what is WP Racing? thats a decent price for front and rear if they are any good!

Has anyone put either of these to the test? or opinions?

AP Racing Vs Alcon? opinions? Im considering these for the gtr..

I was looking at those cheap chinese 8spots. I mean they are pretty damn cheap, but then i was considering the externder brackets with the 343x32 rotor with the stock calipers.

Usually i avoid chinese stuff would be good to hear from anyone who has actually used them.

I've got them on my Cosmo - awsome brakes. Build quality is good. I wouldn't say that smaller pistons is neccessarily a bad thing - There are 8 of them - and don't forget the stihiletto effect.

To get a little technical - Before the upgrade - I had 10% stopping difference between the left & right front brakes. And front rear bias was 60% front 40% rear.

After the uprade - there is less then 1% difference between left & right - and bias has incresed to 85% front 15% rear.

Seat of your pants measurements - Before upgrade, brakes were spongey and pedal had to be pushed down 1/3 before anything started happening. After upgrade, I can just apply a small amount of pressure and the pedal moves no more than 5-10mm before you come to a stop.

First time I drove it after the upgrade, and braked - I narly went through the window.

For the $$ - I reckon they are an awesome upgrade.

BTW - Mine are K-Sport - but they are exactly the same as G4 !

Cheers,

Actually - the calipers are pretty big - here's a shot - those wheels are 18's as a comparison - (the brakes won't fit unless you have 17's as a minimum)

Between AP, Alcon and brembo, there is bugger all difference ask any supercar driver, they are running one of those three brands and they all pull up the same and they dont run control brake rotors or anything yet, but it will be in place shortly.... Just decide what you like in terms of the big three. I like Alcon the best but thats because I like dealing with PWR who are the importers for alcon...

I havent heard of these other brakes might look into it for my street cars,

Cheers

is it not necessarily a good thing to have so much bias at the front? Eg my car has no ABS, if i had a bias like that, i would be locking up the fronts prematurely, yes?

your right they dont look a bad size! what size are the rotors?

you guys say you can run an AP 6pot pad, this is saying the pad area is the same as 6Pot AP setup, and is hence bigger pad area than a GTR brembo front setup that i was going to put on?!

gee im thinking it doesnt sound bad for the price now!

How about WP racing? Anyone know who and where they are made by/at?

cheers

im still reluctant.. but for the money. you cant compete.

i have the same opinion, you cant compete for the money as most aftermarket options of that size are double the price plus. But that said, if they dont last then that would make them a bit of a waste of money!

They look ok from the outside, but id like to hear from someone who really knows brakes inside out who knows whats INSIDE them and if they are actually assembled with any sort of precision! Remember China made stuff is made in China for one reason. Its CHEAP to have stuff made there. Now im not sayiing everything from china is junk, but i would say that the big names like AP and Alcon etc, are expensive for a reason!

If i see someone using G4's/China equivalients on a successful targa car id buy em right now :whistling:

This is the way I look at it... Some stuff from CHina is rubbish, but some of it, while not the highest quality product in the world will get the job done. For example I have seen various intercoolers made in china... the $130 units are absolute crap they are very thin and dont do the job the $350 units are good and I have personally had good results with them they do the job and they may not be asas good as a PWR or Jap brand you have to ask yourself how serious am I really?? If im racing professionally etc then sure buy the best...

Now as another part of my response there is no way these items will compete with the big three who are the brakes on F1 cars through to nearly every form of top level motorsports from rally to sprint cars to v8 supercars... these companies spend money on R and D, x-ray test, metalurgy tests for heat disapation verse weight verse longevety and it goes on... their machining and manufacture process is perfect and you pay for this you have a product that is race proven and you never have to ask yourself " whats the quality like" or "will they always work" casue you know the answer. And yes alcons and ap's are ridiculously light for the size of the caliper, this relates to the manufacture process and the material they use, it all top class stuff.

Saying this I can't see the aftermarket China ones being any worse than alot of factory fitted stuff, luckily Nissans have Sumitomo's and they are quite a good construct to start with. I don't think its a case of buyer beware the stuff has 1 year warranty, I think you just need to ask yourself can I get my standard stuff to out perform most road tires??? The answer is yes!! and secondly if I do upgrade do I do other stuff to make it worthwhile..

Cheers

At the end of the day, they are a billet caliper so the quality should not be an issue. Even if they are made in China, they are machined on an automated line and using billet. Its not like the quality of the casting etc is called into question.

Comes with big rotors, hell, the rotors alone are worth about $1300 so they are a good buy

After the uprade - there is less then 1% difference between left & right - and bias has incresed to 85% front 15% rear.

thats really unsafe! you jump on the brakes and you are essentially only using the front brakes. if i brake hard on rough roads i usually pinch a front brake for a split second. if i had that sort of bias i would be locking the fronts all the time and take longer to stop. the only good thing that sort of bias is good for is power skids.

if you are going to upgrade the brakes, do both ends.

nehting over 330mm is an overkill on the streets imo

if 'purely' street then you maybe right, but factor in the odd track day and bigger the better i guess..

Talking to racebrakes in regards to 345mm fronts vs 360mm fronts for my GTS, they told me "the 345mm setup will do everything you want. Full Stop." I cant remember the exact words he used in regards for the 360 setup, something like they are just totally awesome... Personally i would go for the largest rotor size i can fit under the rims, as im running 18's on the GTR i think the 360's will be just right.

Fitzpatrick Speed Works, can you shed any light on WP racing gear? They are significantly cheaper than the big three, yet not cheap enough to consider them "cheap", at under 7grand front and rear.

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
