i have used a few of these.

 

these fit behind the drum and backplate,and bring out the rear wheel by 10mm.
20mm if you use 2 of them.

 

Caliper placement?

 

i have drum brakes,lol. so not a problem.

would they fit a disc set up ?rs2k? then use a caliper spacer.

 

Is a good idea for drums.

Not so for discs. Seems alot of agro to use them, then use Caliper spacers too? I've run hubcentric spacers on mine for years now without problems.

 

i cant get my head round i for the rear.wouldnt you be spacing the drum out from the hub and the bit that the shoes go on to to stop the car?

 

it goes behind the back plate,the bit that the brake shoes attatch to.

ie. undo the 4 bolts that hold the stub axle to the beam. drill out the rivets that hold the back plate,if they are not allready broken to the rear beam.then fit this inbetween the beam and the back plate.

they are also available in a angled state.so you can add camber to your rear wheels.

 

ive made a few of them for mk3 fiestas years ago
