I have a 79 super with 7.5 cooper s front discs 165 70 10's and standard rear set up.

Just a thought really as the front 7.5 cooper s set up is a wider track than the origanl front drums should I be running rear spaced drums so its all in line?

Any help or thoughts would be great.

Yes, but not so it's inline! The front track of a Mini is wider by design but fitting any of the large CV discs at the front makes it another 2" wider again. The spacer drums were created to resolve this.

Ok thank you so how much wider are spaced drums? Would this make the handling better?

They have a built in 1" spacer each, adding the same 2" to the track that the discs do. Yes you will notice the difference. Remember you will also need 1" longer wheel studs.

Ah great many thanks for your help, can you fit new studs without removing the hub?

No, the hubs must be pulled to fit the longer studs.

Also, if you run with 'S' rims, they won't fit the rear unless you have the spaced drums.

On the rear you can just about get the new studs in but its best to remove them as any hammering is going to damage the bearings. just becareful when you remove them as they can fall apart, also some have a spacer in the middle.

And always ensure that the area is clean so that no dirt or foreign objects enter the bearings.

Some hubs only have one retaining bolt hole depending on the age.

Some of us don't bother with those drum retaining screws as they are not essential and if not removed regularly they can seize on. The wheel nuts hold everything together as on a lot of modern cars.
