Just to add now weve sorted piston sizes out, a lot of the Mk4 kits are being touted as suitable for the Polo
Mk4 Brackets can have a straight mounting face which are cheap to produce such as these
As you can see these carriers can be manufactured in essence with two "passes"
The mounting lugs on a Mk4 are proud of the hub casting so you can get away with this more affordable way of manufacturing bracketry
The Polo lugs are recessed so the bracketry needs to be designed accordingly
Just had this snapshot from solidworks - hopefully you can see what I was making a fuss about
We've got the old Mk4 330mm 996 Front Kit we've adapted for the polo, thats on a 28mm front disc and will work well on track days
And this NQSBBK variant for the polo
Ive refrained converting the 996 Turbo Calipers for the Polo onto the Mk4 R32 Disc.....
And the GT3RS Ceramic 6 Pots.....
And the Carrera GT Rear Calipers......
I do however retain the right to mod the design for the first person to attain 350BHP out of the Polo
