There are a few others which i may have missed, please feel free to post them and i will add to the list
It is interesting that most people have had 4 pot monoblock, as the monoblock is an improvement over the split caliper, but the rear upgrade is only available in split calipers

What was the official view of Split Vs Mono block????

Looking at the TS.net Movit Group buy for my S3 as an example.......

S3:
322*32 4S3
4pots diameter: 36 and 44mm
75.5 cm braking surface
price:1725Euro or 1,144.22 GBP



322*32 4M5
4pots diameter: 36 and 40mm
72.5 cm braking surface
price:1613Euro or 1,069.93 GBP

where the 4S3 kit is the best since it got slightly bigger pistons (pots) and a bigger brake surface and it gets less hot than the 4M5 type kit

Slit appears better than monoblock in this case...

bigger piston... and bigger pad surface area for same given disk...

I was always told monoblock was the preferred choice.... now im not so sure..

Paul, you have an odd example there

mono are alledgedly an improvement on split as they dont allow a build up of road dirt and salt where the pads are held in, which on splits may stop the pads moving correctly

but then the increased area and braking force is definitely the way to go

one person has voted for the 6 pot upgrade

How do you find these?

Any problems with the standard rims?

Waaah, where's the option for Brembo 4 pot monobloc [img]images/graemlins/tongue.gif[/img] [img]images/graemlins/wink.gif[/img]

After all Brembo make all the others, they must keep the best stuff for their own brand [img]images/graemlins/wink.gif[/img] [img]images/graemlins/1syellow1.gif[/img]
