G4 Brakes

[tacker]

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.

Interesting bud which particular kit did u get fronts only or front n rear disk size? How was it to fit brackets and lines with kit? Sorry so many questions pretty keen to get brake upgrade for my 32 maybe

[tacker]

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.

Yeh "better to be looking at it than looking for it."

No issues with the standard booster still feels nicely balanced?

[tacker]

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

Thanks for the feedback mate, good to hear.

From what I've heard so far these seem to be quite a good thing for the money.

Tacker,

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

Andrew, im pretty sure they are $2599 for the kit that comes with 356mm rotors.

[tacker]

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.

Do post up some pics man..

keen to see how they look on your car..

Cheers

[tacker]

As requested,

but forgive the rusty strip on the inside of the rotor as i should have painted it before i put them on we have huge humidity here and everything rusts.

[siddr20]

That looks really nice..

Wow are those Full slicks?

[tacker]

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.

WOW.

VERY happy to hear this. I have been looking at this kit for a few weeks and was unsure about the quality of it.

I think I will be adding this kit to my upgrade list.

Thx for the info.

Got a few questions..

How are the brakes just for everyday driving?

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

But good to hear you guys are happy with it..

[Duncan]

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

[T04GTR]

well il be honest. im very suprised in these results. very cool

[SLY33]

good to hear positive results about these "cheap" upgrade brakes.

Id like to hear from street users without ABS, if possible!

Great to hear a product half the price of competitors performing well, sounds like good bang for buck.

lol I am kinda half that.....no abs but it was on the track. But its not just the calipers and pads, you need properly bled, new fluid
