AP Racing kit added:



piston size/area



1. stock front caliper:


Golf/GTI - Ate FN3 54 mm caliper: 2290 mm˛

S3/R32/R - FNRG 57 mm: 2552 mm˛



2. aftermarket - proper match:


AP Racing 6-pot CP7068-00 (355x32 ) > 2350 mm˛

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

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

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




3. aftermarket - poor match:


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

Q7/Touareg/Cayenne (three variants):

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 diameter:

- 22,22 mm > 388 mm˛ (Mk.V GTI)
- 23,81 mm > 445 mm˛ (Mk.V R32, Mk.VI GTI, Golf R)
- 25,40 mm > 507 mm˛ (RS3 + TT-RS)



ps
If you know the piston diameter: Pi * radius˛ = area

AWESOME!
Great info. Keep this updated and once a "semi complete" list is made Ill put it in my OP to make it easier to figure out the total area for each kit.
Install was delayed due to my friend with a garage to use had the flu so I wasnt able to go there and install this. Hoping for this weekend

I've got a question on the Touareg calipers. I know that these fit on our cars:
17Z VW Touareg - Driver 7L6 615 123 T - Passenger 7L6 615 124 H

But would these fit as well?
17Z VW Touareg - Driver 7L6 615 423 H - Passenger 7L6 615 424 G

ughh why did I have to look at this thread again which made me check ebay and found an amazing deal on a pair of these calipers. So now I am a proud owner of the calipers.

The deal was to good to pass up now the question is will these calipers clear 17" wheels the specs of my wheels are 17x8 ET40?

Ok so I got my Calipers and went to swap the crossover tube and the things are really in there tight. I tried to do it with a crescent wrench and it would not budge and the wrench actually slipped. I don't want to strip the bolt so does anyone have any advice on getting the tubes off the calipers?

Argh...DON"t use a Crescent wrench.. As I recall those are 10mm (7/16ths on the stock caliper). Use a 10mm open end, or, if you've buggered the nuts, use a 10mm flare wrench (which is a 6 flute Box wrench with a slot cut in it for fitting over the tube). If you really screw it up you can buy new crossovers, but Brembo parts are generally not cheap..

From what I can tell, those are the rears. for driver and passenger sides, respectively.

They're also a 4-pot setup for the rears. Not sure if they'll fit size-wise; but it may be best to source the boxster non-S rear calipers (also 4 pot) because they definitely fit the GTI, and save yourself the guess work.

Awesome Modshack thanks, that worked with a regular 10mm open ended. I didn't mess up the nut, I only tried it twice with the Crescent so it did not round the nut so I'm fine now.
