Looking to upgrade to 345mm front brakes. What else is needed apart from the calipers, carriers, discs & pads?
Will the bigger discs fit behind 17" monzas?
-
you will need the brake hoses as well
should fit behind 17" wheels
-
As above you will also need hoses but that's everything, they do fit behind some 17" wheels and the Mozas are one of them :happy2:
-
You don't need the braided hoses as you can use the the flexi pipe designed for the front
-
As above, standard R32 hoses will work, but having done this upgrade myself on my GTI, I'd go for braided lines as they really do make a difference to the feel of the brake pedal. They provide much better feel through the pedal, gives you more confidence in the brakes.
-
Thanks guys :drinking: how about the brake guards?
-
You can either bend yours out of the way or fit the r32 ones like i did
-
ill be getting the proper ones, do the job properly. What brake fluid do you recommend?
-
I just used dot 4 what we have at work
-
OEM fluid.
:happy2:
-
cheers :happy2: how do they feel compared to the standard set up, especially when braying them?
-
Excellent mate,my pedal is razor sharp
-
I have the rubber hoses with this setup on my Tiguan, pedal feel is fantastic.
I had braided with my Eddy, didn't feel significantly improved to me.
-
Brand new braided hoses come with the calipers as a deal anyway :happy2: what are peoples thoughts on drilled & grooved discs? Ive heard they crack quite easy?
-
The initial bite on the R32 setup is very good, better than my 4 pots.

But the 4 pot better right?
I'm looking into a brake upgrade for my stage 2 eddy and unsure what to go for
R32/s3 setup
Nqsbbk
Small 4 pot set up using ttrs calipers or toureg calipers
-
The stop better for sure.
-
Like Rich said the initial bite on the R32 kit is great but the real difference is in the last 30% of the pedal where with good 4pots your eyes feel like they're gonna pop out .
I highly recommend TTRS calipers with AKS/ DaveB adaptors and TTS 340mm discs along with some decent pads, gives good pedal feel (some may say a touch soft but I like it as you don't jerk in traffic). They stop like you crashed and the consumables are cheap. MTEC discs £140 decent pads £120 - £170, obviously there are more expensive and better options but still plenty of good stuff in that range.

Thanks for help mate I'm abit unsure wether to save the extra pennies to buy a 4 pot kit like the ttrs over the r32/s3 setup
Havnt got an endless pit of money and I want to do some suspension upgrades and a few other bits too!

18Z Brembo are massive 6 pots
TTRS 4 pots both can use 340 discs
whats the better option ?
and what disks EBC and yellow pads or better options pls advice

It depends on your driving and whether you're going to track it, stage 2 eddy's aren't slow and need some stopping, however of your not too aggressive as a driver and don't plan on doing regular tracking then the R32 set up with good pads/ discs/ braided hoses and fresh fluid will get the job done. Its really those 105mph+ stops where the 4pots come into their own.

I'm not sure between the 18z 6pots and TTRS 4pots, its not just about how many pistons but also the size and how it matches your car, the TTRS calipers are basically perfect from what I gather and match up very well with the MK5 platform.
Pads wise I havent tried EBC yet although the Yellow stuff pads will replace my Brembo Sport pads very soon.
Discs I really like MTEC as they're well priced and havnt had any issues with the 3 sets I've used from them.
Also I think the 18z calipers use a 350mm ML disc not 340mm
-
The 18Z are a bit oversized for the OEM GTI master cylinder. Going down that route really needs to be accompanied by the TTRS master cylinder upgreade.

i think mk6 Gti golf have better master cylinder ?
so what would happen with mk5 GTI type ?
also AKS/ DaveB TTRS 340 DISK adaptors is about £200-250
-
Adaptors are £250 and TTs discs are £150 odd, so about the same price as TTRS discs which arent very good but a 3rd of the price to replace and you can sell the adaptors at the end

I haven't read any bad feedback online about the 18Z from people who actually fitted them, just from others who look at the numbers that really don't match. The GTI can have 2 different sizes master cylinders, a 22,2 mm or a 23,81 mm.
Mine has a 23,81 mm that can be easily seen by looking at the part. My GT Sport has a 22,2 mm MC.
All mk6 GTI have the 23,81 mm MC.
MC list:
-22,22 mm (some mk5 GTI)
-23,81 mm (some mk5 GTI, mk5 R32, mk6 GTI, Golf R)
-25,40 mm (RS3, TT-RS)
My mechanic who is very picky with the mechanical work of every part was happy with the pedal feel and brake power of the front 18Z with the rear R32 brake setup. :smiley:
In the end I got what I was looking for, a BBK that didn't required wheel spacers at the front, with OZ Ultraleggeras. :grin:
With the TTRS calipers I'd need a small spacer and I would have gone for the AKS/Dave B adaptors too (would increase the price of the setup).
Both setups can have cheap enough discs and pads.

you can also go with 6pot 17Z calipers with 330mm discs, the good part about them is that you can use them with 17inch wheels and the fitting is very easy

AFAIK the 17Z have even bigger pots than the 18Z (that have 3 different versions with different pot sizes).

Brand new braided hoses come with the calipers as a deal anyway :happy2: what are peoples thoughts on drilled & grooved discs? Ive heard they crack quite easy?
opinions?

Grooved discs are enough for me. J grooved preferably. :happy2:

Save once and buy once mate - I did the r32 setup and loved how good they were in comparison to the std setup but I did some other mods which meant I felt less comfortable and ended up upgrading the brakes to give me more confidence- I highly recommend AP racing brakes. Prices but worth it!
-
Seconded for AP. I came the same way, through S3 fronts. Car and I out grew them on track and I have 6 pot AP's with floating rotors. Staggeringly good brakes whose residual value should they be removed is high. They'll also upgrade newer vehicles such Mk7 Golf R etc. Road only use I'd suggest a neat light weight 4 pot kit from them. If cost is an issue then the S3 kit front and rear is a very good upgrade, particularly if you won't be doing track days. On the road they are easily good enough for 350bhp with the right pads and fluid.

Are 340mm TTS discs the better option over the 345mm?

I've replaced 345 mm ATE (12 kg) with 340 mm TTS Brembo Sport (10,1 kg). Same brake power, but less weight. Enough to be noticeable. Noticed right away a lighter steering (placebo effect maybe?).

Thanks Shoduchi, I presume these are the ones you had? http://www.eurocarparts.com/ecp/c/Audi_TT+Coupe_2.0_2009/p/car-parts/brakes/brake-friction/brake-disc/?10444820A&1&e7d6f9db682686d4cf1d8ab5c1bd9d6341a06307&000027

Yeah, those. I was lucky that they were cheaper when I needed to order them. :smiley:
-
will pads made for the 345mm still be ok on them?

I made that question in the forum before I had the discs fitted. Everyone said it was fine. The discs won't have the outer border lip with the R32 pads. I didn't notice anything different so far (after 2k miles still).

Cheers mate, TTS discs it is :drinking:
-
I have 18z from touareg v10 and discs from R32, 345mm... all fine except calipers are close to rims, that paper hardly can go between :laugh:
