NQSBBK Porsche Boxster 986 front calipers
breeze:
I’ve just cut and pasted from elsewhere, so forgive me if the source is innacurate:
Brembo 6 pot 17Z - pistons 34/36/38 = 3060mm2
Brembo 6 pot 18Z - pistons 30/34/38 = 2750mm2
I think I would notice that.
I ran 840ci Brembos on an M3 Evolution years ago. Took me a while to figure out a. why the pedal was so long and b. why the rears wore out so quickly. :doh:

From the post above, it sounds like they are a good fit. Not that I’d trust an MOT to tell you if they weren’t!

FWIW, I found the difference in pedal feel between standard fronts and MK7R/S3/PP, was pretty substantial....and not in a good way.
Before fitting the MK7 calipers, the front>rear balance always felt spot-on to me, but post fitment, the first cm of pedal travel was dead (a horrible delay at motorway speeds when feathering a little speed off) and the rears no longer contributed much, so the balance was ruined.
I've since gone back to stock and much prefer it. I think the MK7 setup only works effectively when everything else from the car is transferred over. Servo, pedal (different fulcrum point), ABS ECU, rear brakes etc etc.

I have TTRS calipers on mind IIRC 40/44mm pistons and the pedal is fantastic.
