GTI Brake Setup.

[blkpolo]

You can normally pick up 256 rears for about £120 with some naff discs and pads.. Personally i wouldnt bother. Why? I fitted them to mine and about 3 weeks later they developed the known "moo" when reversing. I dont know of any that dont do this (without fitting an anti mooing kit), and i would say that for the embarrassment and annoyance of the noise they make, they just arent worth it.

I havent noticed any difference in braking ability, and they barely look any bigger so its not like it fills out the wheel or anything because as mentioned, the guard has to be butchered to fit them.

I think you would be better off upgrading the disc and pad as being smaller they are generally cheaper anyway!

You can use the 4wd rears but need to run spacers. I got mine from a Golf Anni.

Apologies for the rant - bad day lol.

I also have the "moo" after fitting these. What causes it and is there a fix?

[aarongti]

I am running 288mm and 232 mm rear I have used mintex discs and ferodo sport pads and the braking is immense no brake fad and never struggles no matter what speed I am doing. I have the 312 mm set up on my golf gti and I have to say the polo is far better.

Interesting.. What power output is your GTI?
I fancied the Tarox G88 Discs with fast road pads but the price is ridicolous.

[aarongti]

Starting to consider Tarox or even Black Diamond discs with fast road pads.

Anyone know if a setup like this will be good for around 200bhp?
Or are the 312mm the safest option?

[RITCHAT]

I would go upto the 312mm if you are going beyond 200bhp its an easy upgrade with parts readily available through ebay etc. I find putting the type of car you want to use as the donor with breaking(not a spelling mistake) in the search request will bring up various models that are being broken down and scrapped.

id upgrade the 288mm setup. mine only gets used at weekends and its hard use at that.

im still on the original vw discs and pads and ive never felt them lacking to be honest

Hahaha that made me laugh, I have the moo'ing issue too! Least I'm not on my own

I have 312mm and the 256mm set up! Stopping power is pretty damn impressive on the road, yet to test it on track (soon hopefully) but after reading this topic they may take a while to get used to when going hard on track!

[aarongti]

Im thinking of going for the 288mm tarox upgrade.
Sport Japan discs with Strada pads.
Whats the thoughts on this? Will it live up to or come close to the 312 setup?

[Instigator]

@ritchat: you can't really compare a Golf with a Polo mate.. to much weight difference.
so offcourse a polo would brake better with 288mm with upgrated discs and pads.
put the same set up on youre polo with 312mm and you will be stunned

@Aarongti: Tarox G88's are verry good indeed, but you pay a price for that.
i have national sport discs and they are superb also!
my next pad upgrade will be carbon lorraine i think.

and about a 200Hp polo and what brakes it should use,
stock brakes would be good enough, but bigger will be better, so 312mm can get rid of the heat more quickly so they won't fade as fast as the 288's.
apart from that, not really much diffrence just that 312mm's would brake a bit better also.

[aarongti]

Bump..

Anyone else care to contribute to this with their thoughts?

Hey mate, here is my 2c's

I have tracked my Polo a fair bit now with slightly over 200hp at the wheels and the following set-up perfect with no fade or surprises even on 30 min sessions going as hard as possible on a demanding track. And the brake feel and force is brilliant and very controllable on the track and street.

Front brakes - Stock 288mm size rotors but upgraded to RDA slotted rotors, TWR pads in stock calipers. HEL braided lines.

Rear - 256mm Audi TT rotor and caliper upgrade. Once again RDA slotted and ventilated rotors with TWR pads. HEL braided lines.

Fluid - Penrite Syn 600 brake fluid with a good bleed.

This is a massive improvement over stock and quite a cheap upgrade. Also going bigger on the rear helps balance the car under heavy straight line braking where the rear tends to get loose especially if you have taken out your spare and rear seats for 60 odd kilograms of weight saving. Even if you don't take them out I feel the factory brake bias from front to rear is crappy anyway so this helps with day to day driving also.

I am just about to put a bigger turbo on so have upgraded to 312mm front rotors with Brembo calipers which are amazing but not necessary at 200whp imo.

Cheers

[RITCHAT]

I dare say I would be stunned with a 312 mm set up but as it is I nearly get put into the windscreen if I brake hard. I am now just wary of arseholes sitting close to my rear as I know I can brake in time but can they??

[Mr Blobby]

4 pot Brembo's from a Seat Lean Cupra R is where its at!

323mm front disks with corsa pads and braided brake lines, no fade at all and massive stopping power! Such a good upgrade over the standard ones...
