even for using rear calipers?  :huh:

my boss has a boxster S with paint peeling off the rear calipers... he told me today he was buying a new set purely because the paint was coming off! so i may make an offer on the old set, will be cheap  :smug:

Ok i'll let you know, the 280mm setup works fine but it doesnt hurt to have more braking power!

I have a G60 master cylinder, would this be enough for a porsche caliper setup?

according to that thread, you can use certain 15" wheels, so i might be ok. Also they mentioned 280mm discs :afro:

Now, how do i go about carriers....? im guessing theyd need fabricating?

Could probably sand-cast them for you if we can make a female mould on the vacuum former. Anything is possible

Yes G60 Master CYL will be fine!
The Alloy clearance must be ET38 or ET37.5 (Rare LOL).
Compomtive was the only smaller alloy with an oval shape hub clearance under 16!

sounds like i'd have issues with 15" ET35 MIMs then

well the 280mm setup works great at the moment so i will bear all this in mind

Chris you judge have a look at my alloys both 17" are ET38! Not much room non?

That will be a tasty setup, what size are the new calipers?

Is the G60 M/c and servo bigger than say a 16v? 22mm and 9" respectively?

Don't suppose you know 'Flash' around Yeovil quite a bit, he drives a white mk2 BAM lump? He has brembo 4pots under quite a small wheel.

If you can get a set the "Standard Boxster" Calipers thay are Smaller than the Boxster S Ones...

986 Boxster Fronts...  986-351-421/422

986 Boxster Rears...  986-352-423/424

Front & Rears are the same size but pistons are smaller on the rears....

yes I dont know the chap but ive seen him (apparently) in ilchester (when someone posted on here about a stolen white mk2 from ilchester).

also this evening I saw an old maroon polo saloon on what i assume were ats wheels (with massive stretch) and a slammed red polo 6n2 or 9n(?) hanging about in the same area!

anyway i digress.

i think the boss has realised the cost of new rear calipers for his pansy boxster S, so there goes my brake upgrade  :angry:

clipperjay what diameter discs are those? over 300mm? apparently you can use these calipers on a 280mm setup (which i have). point being i might get away with a smaller wheel...?  :huh:

Tell your boss to stop being such a ghey, if he doesn't get new rear brakes the people will question his sexuality even more etc etc.

Seat cupra turbo 304mm
I would be careful about smaller calipers from a standard boxster the mounting holes might be smaller for the RS2 carriers as long as they are match for your mount holes (Carrier bolt center holes end to end 13cm) they would be fine, but like I said I had a set of black ones and they didn't fit had to be Boxster S's rears

Seat, that’s a 12" or 28mm thickness-304 mm diameter 4 X 100 Seat Ibiza Cupra R 1,8 turbo on old platform ('00-'02  )  Seat Ibiza Cupra R

These are Boxster’s rear part numbers for Callipers’.
996 352 421
996 352 422 are good

Standard Boxster Calipers also have 130mm centers for mounting thats why so many early boxster owners upgrade to Boxster S Calipers...

Also you dont wanna buy RS2 Carriers either as they are a fortune... Look at these... I have them on my S2.. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260650623665

Better value and better quality....

The RS2 ones are just a casting.. the other ones are machined alloy and are very light... I have a set on my S2!!

Most peeps on the S2 Forum like these better!!

Well if he wants to go down the route guess its all good!
If the RS2 chaps like them better, then there should be loads of RS2 spare carriers going cheap then? :wink:
