Having fitted 7.5 inch discs to a drum braked mini the front track is now wider than the rear.  What size spacers do I need to bring things into line.  I have fitted spaced drums to the rear but still not wide enough.  I realise I will have to change studs.  Many thanks

The front track on a Mini and in fact most cars, is wider then the rear track.

Fitting the spacered drums as you have is also how the cars were produced at the factory.

Thank you but does not look right.  The fronts sit with the wheels just protruding a little under the arches yet the rears are set inside.  Can I fit spacers with spaced drums.

Don’t. The drums for the rear disc set up have a built in 1” spacer. That is all you need. There are other drums that have a much smaller spacer though.

Wise to fit disc brakes up front...Minis are up against ABS equipped vehicles some with auto avoidance capability.  First bit of advice I give to new owners of drum braked classic Minis.

 

Though to be fair, we have an 86 year old owner of a MK I Countryman with single leading shoe drum brakes in the club and he manages to stop OK.  An experienced driver, he wisely leaves braking distance between himself and a leading vehicle.

 

As for rear drums the Cooper S drum will square up your track.

 

From observation, most 5" x 10" and 5" x 12" aftermarket wheels, will see tyres outside the body work.

 

I liked Minilite alloys in 5" x 10" but like the Cooper S offset alloys that keep the rubber within the body work.

I have Cooper S disc brakes and Cooper S offset 4.5/10 Steel wheels (Repro) on my Estate, and they sit in at the back, my car does have 1 and 1/4 inch spacers for the rear wheels and is very tight behind the wheel to wheel arch, so much so that I can't fit a 165 tyre to the rims.

I suspect my car may have been in an accident in the past....
