Jarno,

Let's set the record straight. I owe you the picture! You have helped a lot. I had no clue where to start from, and you have given me a full plan on where to go from here. I will post before and after pics of the car. I will shoot some pictures of the engine tomorrow and post them up.

thanks m8, my curiosity will be very gratefull! But your welcome too, but always double-check everything you order, not that I don't trust my own advice, but I know how stupid people working at VW-dealerships (and especially at the parts-section) can be. I got myself wrong parts couple of times, so make sure to check it before fitting anything (which will make you loose your ability to return them)

It's worth it, because it is a straight swap, which will give you more then enough braking power.

What you will need (for the front brakes):

-the brake-caliper mounts from a Polo GTI (number 4 on the picture)



With these you will be able to install the brake calipers from a VW Corrado G60

-brake calipers VW Corrado G60 (these WILL NOT fit the original 1.4 8v mk4 Polo brake calipers mounts!!!)
-VW Corrado G60 discs (or for instance Zimmermann, ATE or Brembo discs that will fit the VW Corrade G60)
-VW Corrado G60 brake pads (or for instance EBC, Ferodo or Brembo pads that will fit the VW Corrade G60)
-brakehosing from a VW Corrado G60 (or for instance Goodridge ones which are steelinforced ones)

For the rear you will need:
-the rearaxle (including all brake calipers, discs and pads) from a Polo mk4 1.4 16v (100bhp edition) or the mk4 Polo GTI (the axle of a Polo mk5 GTI or Seat Ibiza Cupra 6K will fit too, but require some modifications)
-also here you can choose to take different discs or pads or brakehosing (grooved and/or drilled discs, higher-compound pads, steelenforced brakehosing etc. etc. for more brakingpower)

All of this can also be installed with the original VW ABS system, since this is available on the G60 and Polo 16v or GTI brake calipers

Now that I have helped you a bit, I demand som epictures of that V-Tec of yours lying in the front-end of your Polo (I'm curious to be precise )

apart from the avalabiltiy of G60 parts what benafit would you haev over Seat Cupra parts. ( apart fom g60 are 2 pot and cupra are 4 pot bremo the same as the fabia VRS) IIRC there both 305mm disks (11" inches)

as for the rear you dont need the compleate setup.

when i did my rear disk conversion i baught the whole rear beam for £100 less work for the scrapyard.
but in reality all i needed were.

Disks
Calipers and Carriers (ive been a t*t and realised i told jarno the wrong name (caliper cariers = caliper mounts)
Stub Axles
Hub
Splash guards (not necacerry just stops stones getting jammed in teh back of the disks.)
handbrake cable (from donor car as it has a different fitting on the one end)
brake lines. (probly should have made them new, as there all rigid lines on the back.)


another point to note is that not all 100bhp mk4 (6n)polos have rear disks. i its only post 1998 that have them.
i took my conversion from a 1999/2000 reg MK5 Polo 1.9 diesl. as they have bigger brakes and 14" steel wheels.

You answered the first question yourself indeed, Cupra brakes will have the preference, there are also enough up-grades available for these brakes. But a standard Corrado is doing 160BHP, like he is, and weighs about 233 kilo's more then a standard 1.4 8v mk4 Polo, so the 2-pots G60 calipers will definately generate enough braking power, especially combined with up-grade parts like different discs and pads. Since these discs also aren't that "wide" (280mm) and considering the (possibly) low weight of the car (I don't know how much the weight increased after installing the V-Tec engine), I would personally go for the G60 set-up, since I believe it will be mroe then sufficient, and have less chance of "blocking" the wheels (and more "road-driving-proof" if you understand what i mean by that)

About the rear-axle, I didn't know not all 1.4 16v 100BHP editions had rear-discs in Holland they do actually, probably a difference between nations. But the 1.4 16v 100BHP mk4 was only introduced in late 1997 here in Holland, so that's probably the explaination there aren't any ones here with drums on the rear-axle.
By the way, a positive thing about the Cupra braking (at least for the rear ones, from a Leon, probably for the Ibiza's too, as for the front side) the calipers aren't made of steel, but a leightweight alloy, I believe aluminium, but correct me if I'm wrong about the material, the point is, they lighter then Polo mk4 ones
