Is it better to fit the caliper to the front or to the rear of the disc ??(if you know what I mean!!)

To the rear, usually.

...why is this the case?

Depends on caliper,fords sierra/granada rear calipers normally sit on top.
If you move them from this possition they can air lock when bleeding.

Mine are at 10 o clock on the indy so i had to pressure bleed them

On ours they are either @ 3 or 9 o'clock.

Mine are there all the time . I can't see any difference as long as the pads grab the disk. We fitted a leading link conversion to a bike combination and it swapped the calipers side for side and to the front, they still worked the same.

I mean the hub carriers can be swapped around!

this has been talked about before. IIRC it makes no difference to the brake torque/forces where the caliper is mounted. f1 apparantly put them under neath so as to reduce CoG, but I'd rather have them somewhere they can be bled easily. i think there was some mention at teh front if they were mounted in front it might help turn in, but i think the advantages would be microscopical.

If you put the calipers at the rear, they support the weight of the car taking stress off the bearings. Put them at the front & stress on wheel bearings goes up.

alternatively, put back ones at the front and front ones at the back to reduce polar moment of intertia and shorten brake pipe runs.

Alternatively conclude it doesn't actually matter very much.........

PS 4pot calipers ARE DIRECTIONAL - get 'em wrong & you'll taper your pads

I'd put them in the orientation that makes them easiest to bleed (ie nipple in topmost position).

Thanks everyone,I think I'll try both ways and see what looks the best and works the best !!

I think you are missing the most important point...the routing of the handbrake cable. I mounted mine on the rear of the disc so that the cables had a clean curve.
