312mm brake upgrade - a warning

[Lex 696]

ABS sensor works off the wheel bearing so if you dont change the hub you havnt got a prob. Ive got a boca an i really need some better brakes. I understand the 312mm conversion is good but wat is it off an has anyone got any vag numbers? I work for seat an wouldnt mind gettin some brand spankers. I know leon is reduntant cus i have measured them and they are running the same as a mk2 octi vrs ie too big.
Thanks

this is what i have been after. i dont want second hand brakes and an out of the box solution seems to be either impossible to find or if you do (e.g GT Brembo Junior) is too expensive. I am trying to get hold of someone at AP to see if I can buy new parts from them but they seem to be hell bent on not making money as 3 emails and 2 phone calls directly in to the sales team and i havent heard a peep

If your going to pay brand new proces for 312mmbrakes your better off getting an aftermarket solution from the likes of Brembo, same cost even to us.

If you work for SEAT just look up front brakes for a 2001-2005 Leon Cupra.

Carriers are about 120 each, calipers iirc 200 each plus VAT, then 2 discs about 35 each and pads 60ish.

I have a set of mk2 Octavia vRS 312mm discs, calipers and carriers in my garage. I take it these wont fit?

 

[gt4meister]

No mate the mk 2 has a different hub. I've measured them at work an there no go. Ya want mk 1 octy or s3. I'm still after some part numbers cus I want some new ones.

MKII Octavia is 5x112 so discs are no good and as said the carriers are different, different bolts, spacing and offset.

 

[vRSy]

cheers. ill sell them then i guess

 

[freakybug]

Iv got some brembo 4 pots off a fiat coupe turbo I'm going to look at using the original discs just adding bigger callipers and better pads

 

[jj mann]

[jj mann]

[Leoncuprarfan]

Mk1 cupra r disks are 323mm I think but I don't know about mk2

Mk1 cupra r disks are 323mm I think but I don't know about mk2

MK1 LCR is 323mm -These will fit as there 5x100, not sure whats needed to make them fit? Techie?

MK2 LC/LCR 345MM -These wont fit as they are 5x112

 

[jj mann]

cheeers i saw 312mm ones branded for cupra r but 323mm wil do thanks for the info

Easy, 312mm brakes go under 16" wheels.


Calipers however may vary if your thinking four pots.

I'm guessing by this that the calipers from the TT, S3 etc aren't four pots then? What about the racing brake option?

Have a look at your current calipers - do they have FS III cast in to them ?

If yes then you are going to need the front hubs as well as the brakes.

If your brakes have a spring on the outside then you can go for the 312 conversion without changing hubs.
