All Mk.VI GTI should come with the 23.81 mm MC.

If in doubt check part number on MC or PR number on the sticker in your trunk:


Quote:
Golf 5 R32 (2008er) 1K1 614 019 L (ATE)
Golf 5 GTI (2008er) 1K1 614 019 L (ATE) + 1K1 614 019 K (ATE) + 1K1 614 019 F (Bosch)
Golf 6 GTI (2010er) 1K1 614 019 L (ATE) + 1K1 614 019 K (ATE) + 1K1 614 019 F (Bosch)
TTRS & RS3 (2010er) 8J1 611 021 E (ATE) - 25,4 mm

LHD cars only !!

1K1 614 019 L = 23,81 mm
1K1 614 019 K = 22,20 mm
1K1 614 019 F = 22,20 mm
8J1 611 021 E = 25,40 mm


Index L ... 1AC, 1AT, 1AS
Index K ... 1AC, 1AT, 1AS+1LL, 1LJ
Index F ... 1ZC, 1ZE, 1ZF, 1ZP, 1ZD, 1LJ
TTRS & RS3 ... 1AT, 1AS

Here we have Audi TT-RS and Wilwood calipers (included in their 328 mm kit for GTI):




piston area



1. stock front:


O2 RS/Golf/GTI - Ate FN3 54 mm: 2290 mm˛

S3/R32/R - FNRG 57 mm: 2552 mm˛




2. aftermarket - fits properly:


AP Racing 6-pot CP7068 (355x32 ) > 2350 mm˛ (special version of CP7040-caliper for Golf V/VI, Scirocco etc.)

AP Racing 6-pot CP5570: 27.0 + 31.8 + 38.1 > 573 mm˛ + 794 mm˛ + 1140 mm˛ = 2507 mm˛

Audi TT-RS: 36 + 40 mm > 1018 mm˛ + 1257 mm˛ = 2275 mm˛

Boxster: 40 mm + 36 mm > 1257 mm˛ + 1018 mm˛ = 2275 mm˛

Boxster S: 40 mm + 36 mm > 1257 mm˛ + 1018 mm˛ = 2275 mm˛

993 Turbo: 36 + 44 mm > 1018 mm˛ + + 1520 mm˛ = 2538 mm˛

Brembo GT 'A-caliper': 40 mm + 36 mm > 1257 mm˛ + 1018 mm˛ = 2275 mm˛

Stoptech ST-40: 38 mm + 34 mm > 908 mm˛ + 1134 mm˛ = 2043 mm˛

Wilwood FNSL6R: 41.1 + 28.4 + 28.4 mm > 1330 + 636 + 636 mm˛ = 2602 mm˛

Mov'it:
4s2 - 36 / 44 = 2538 mm˛
4s3 - 36 / 44 = 2538 mm˛ (u.a. als VAG-Kit mit 322x32er Scheibe, geht unter 17")
4m6 - 36 / 44 = 2538 mm˛
6m1 - 28 / 32 / 38 = 2554 mm˛




3. aftermarket - mismatch:


Forge: 707 mm˛ + 1046 mm˛ + 1164 mm˛ = 2917 mm˛

Mov'it:

4s4: 40 / 44 = 2777 mm˛
4s5: 38 / 46 = 2796 mm˛
6m3: 30 / 34 / 38 = 2749 mm˛


Brembo 8-pot RS4/R8/Gallardo: 28 + 28 + 32 + 32 mm > 2840 mm˛

Brembo 8-pot RS6 : 4192 mm˛ (!!!)

996 Turbo: 40 + 44 mm > 1257 mm˛ + 1520 mm˛ = 2777 mm˛

Q7/Touareg/Cayenne (there are 3):

34/36/38 mm : 907.920 + 1017.876 + 1134.115 = ~ 3060 mm˛
32/36/38 mm : 804.248 + 1017.876 + 1134.115 = ~ 2956 mm˛
30/34/38 mm : 706.858 + 907.920 + 1134.115 = ~ 2749 mm˛




4. master cylinder:


- 22,22 mm > 388 mm˛ (some Golf V, some Scirocco etc.)

- 23,81 mm > 445 mm˛ (Golf V R32, Golf V GTI, Golf VI GTI, Golf R, Scirocco 2.0T + R)

- 25,40 mm > 507 mm˛ (RS3 + TT-RS)



5. rear:


GTI/RS: C38 > 1134 mm˛

S3/R32/R: C41 > 1320 mm˛

Movit 4m1: 28 / 30 = 1323 mm˛

Movit 4m2: 28 / 30 = 1323 mm˛




Pi * Radius˛ = area

Do I understand correctly that Cayenne calipers will work poor on my mk6 gti?

Right, mate.

You'd suffer from front biased brake balance, increased pedal travel and softer pedal feel.

my pedal is stiffer and shorter than factory 17zs, bais isnt terrible either its there but usable. I did drive a brembro specific bbk 330mm 6 pot vs mine and the bais is a lot harsher for some reason than the cayanne setup.

Does anyone knows if the MC from the TTRS/RS3 fit our brake booster? Is it a strait fit?

Sorry, mate. Still no confirmed info about this.

I just read, if you want (or need) to swap the booster as well, you'd
need to grab the RS3's as the TT-RS booster won't fit the Golf/GTI.

FWIW, the new Audi S1 quattro also comes with the 25.4 mm MC,
while the current Mk. VII GTI and R still have the 23.81 mm one.
