Used my G4 brake kit with a full set of slicks last night and they worked great! No brake fade, no cracked rotors and no burnt brake pads nice and constant the entire night ( 3 x 20 minute sessions ).

Two very big stops on the circuit from around 230kms each, by far a stronger package than standard brakes.

I currently got the 356mm fronts only with the performance pads. The kit itself was very easy to install went straight on with no issues. The lines seem a little long to be truthful but was not hard to run them out of the way. Better than being short i guess.

really couldnt fault them in my car which is stripped out so weight is down a little on a road legal car. With some cooling ducts and 1 hour between our 20 minute sessions.

Also have porsche cup slicks on too which makes for a whole heap of stopping going on when you get on the pedal

Tacker,

Can I ask what you paid for the 356mm G4 kit?

Sorry i cant tell you excatly as i had to have them freighted to Dubai and it was just the one price, but the figure above would be close without the freight.

Speak to just jap they supplied them, and it was 5 months ago so not sure of current price.

Yes they are full slicks i managed to find about 15 sets of part worns.

I did mention that in the posts above as i said there is a whole lot of stopping going on when you get on the pedal. Well thats not quite right you do hit a higher top speed as your corner speed is improved. And you are on the brakes harder but for a shorter time frame as they just hang on sooo much better than the semi slicks through corners which allows you to carry more speed. But all in all i would think that full slicks are harder on the brakes not by much but a little.

I am sure that other will have something to say about it as well, but i am happy with the performance of these brakes. I have them and i have used them a few times now and i have had no problem.

I also ran my G4s at Eastern Creek on the weekend and they were excellent. This is an overwieght GTR (1500kg+) on semi slicks. And a pretty hot day.

I have the 324mm ones under 17" rims - they bolted straight on from what was in the kit.

I thrashed them all day and never had a bit of fade - they also gave excellent feel through the pedal. No cracks on the rotors. And the pads that came with the kit (whatever they are) were perfect as well.

You would be mad to buy any other brakes for a GTR.

How are the brakes just for everyday driving?

fine - I don't know what the pads are or what they are rated too which worried me before I tried them. But they work fine from 0, they don't need heat in the first (which is exactly what we need in Targa brakes since the first stops are always from dead cold as well).

I will put some different pads in when I get back to the circuit racing later in the year so I know what their temp range is.

Also no squealing or anything.

Didnt you guys have to bed in the brakes at all??

I did, as usual I did 4-5 stops from 120-60 until I could smell the resin cooking off, then let it cool for a lap (2min). From there I just gave them hell with no problems.

My only remaining question about them is how well they last over time, eg the porsche aluminium monoblock brakes (gt3 style) get thrown away after each race meet. Will be interesting to see - but even if worse case the gave trouble after a couple of years it is still much cheaper to buy these twice than to buy the brembo or ap stuff once :wave:

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
