What's the benefit of gti6 brakes over dturbo brakes? And how can I tell if I already have gti6 ones just incase they have been upgraded?

They stop the car quicker. Lol

Fair point haha but will they give a better pedal feel?

In short; they have bigger pistons, and a larger master cylinder, so they are able to exert more braking force over the larger diameter disc they use. The larger diameter of the disc will in turn mean that they will dissipate heat more effectively, thus brake more efficiently for longer.

You will be able to tell if you have them already by the diameter of the discs, or the brand of the calliper.

Hope that helps

That's great mate going to be upping the power soon so thought I'd do the brakes as well, bit off topic but what sort of power will a tuned bosch pump, TD04 turbo and inter cooler give?

I pulled 177 Bhp and 247 lb ft on a tuned 9mm Bosch and top mount intercooler at 22psi

I had standard d turbo brakes on that, more power Dosent make you go any faster just gets to speed quicker

But it is advised to get gti6 brakes and I would recomend the gti6 master cylinder too to take the travel out the pedal and got instant braking as you you the pedal

247mm brakes look ridiculous behind cyclones, you'll be able to tell if you still have those or not.

GTi6 brakes will be much better than those, they couldn't even stop my 1.4!

Take a pic of your wheels, we'll be able to tell straight away.

This is cyclones with 247mm brakes (DTurbo ones)

These are mine sorry if it's not great quality it's a bit dark out haha

There definitely bigger than standard hard to say what

Get a tape on the disk if there 266mm there hdi brakes
If there 283mm there gti6

Look like GTi6 brakes to me.

GTI calipers have a set of cooling fins on them that other calipers lack.

Yeah they seem a bit bigger I'll have to measure them, if they are HDi brakes will they stand up to around 170bhp? They seem pretty powerful now but I'm not sure what they will be like at that power

Look like '6 brakes.

GTi6 brakes -



266mm HDi/XSi brakes -



Yours look like GTi to me!

This is where I get my hopes up and find there just HDI haha they do look like 6 brakes though

Even if they aren't '6 brakes, you can pick them up for £30-£60 these days.. Hardly end of the world.

True give me an excuse to put dot 5 fluid in

Plus GTi brakes aren't much better than 266s anyway....its not worth the hassle, cost and extra insurance premium for fitting them imo. I've stuck with the 266s this time for those reasons.

Both are a massive improvement over the 247s that you get on slow cars (1.4s, XUDs etc )...surely you've noticed better stopping power from them than your 1.4?

You say that Tom but all your cars have been sub 130hp.. so agree, it doesn't really warrant the upgrade. If you're going big turbo etc.. then GTi6 brakes are definitely worth it

Definitely! First time I pushed the brake I almost went through the window haha, wasn't used to having powerful brakes

Yeah by doing what I wanna do it sounds like it will be around 170bhp so need all the stopping power I need

I've managed to set fire to 266's a couple of times, albeit that was hard driving down a mountain on one occasion.. But never had anything like that happen on the '6, the stopping power was incredible tbh

With your insurance, you really shouldn't be looking for 170bhp yet imo...obviously that's up to you though.


You are right Danny (though this ones about 135bhp iirc ) but I don't see why that makes a difference tbh, 70 is still 70 regardless of how quickly you get there. And even braking from 90 on the 283s wasn't noticeably better than the 266s, just gave more pedal travel and less sharpness, really wasn't impressed with them tbh! Though I haven't been impressed with any 306 brakes since the Golf, that only used 288s despite its extra weight but the brakes were awesome tbh, even the 180 map didn't make them seem worse so I don't agree with more power needing more brake...theres more to it than size, just buying decent pads would be a good start.

It's not an outright X power increase means bigger brakes by X, but on a twisty road you'll be reaching higher speeds faster and so you'll be braking harder

Tom, GTi6 brakes are far superior to 266's!

As for insurance it should bring the price down if you declare them.

They aren't and it doesn't. . Think it was 40 quid to declare them on mine!

I also don't understand why you're wasting brakes on corners....decent tyres and suspension and just keep the power on. .

currently got 266 on the estate and there good for normal driving but as soon as I hit the back roads to work I can easily cook them / get crap pedal feel horrendous tbh but that is the heavier estate tho and I drive like a tit on my way to work (5am) gti calipers are ready to go on. if you plan on big turbo ect its a good upgrade especially with braided lines and decent pads

I think i have GTi6 brakes! they measure just over 283mm but thats probably because its going over the hub part. heres a few pics just so you guys can confirm for me they seem pretty beefy

Sweet! What rotors are they? I kinda want drilled and grooved ones
