It's complex to do, you can buy everything from Fiat but it won't make you stop any quicker!

Try to find a damaged Fiat Coupe. Here some pics of the first JTD with disk's

He said it wasn't that hard to do...

try to find a BRAVO HGT in a scrapyard, and get the calipers off it. if the disks are decent, then take those too. you'd be as well to put new brake pipes on though, which you can get from fiat, and you'll need a new handbrake cable. i think they will stop you slightly quicker, but rear disk conversions are more for the look than performance.

No, it will not stop you any quicker and don't foget the insurance implications of "modifying" your brakes.

my ijsurance really didn't mind the uprated disks and pads up fromt, OR the uprated conversion to disks on the rear. Male 22, 2yrs no claims (should be more but had a small accident 2 yrs ago,) massive list of mods on a 1.8 and i pay under £800
