Do you have to modify anything under the wheel arch to fit the larger wheels on?

No, not for 12" wheels.

Thanks Doc, your knowledge is endless

Hey Doc my 12's rubbed like sh!t. Is it as a result of my metro setup or is suspension rooted/sagged?

HEYY WHOA!!

Ok an A+ engine won't go into a Morris subframe without drilling some holes and farting around. This is same with fitting a Rover subframe to a Morris body. You have to drill holes in the body (floor) for the subframe mounts.

As for the front cut VS. plain old engine- with the frontcut you get THE LOT. brakes, loom, lights, engine, all that.
Plus, once you've raped the bits off the rover front, you can sell the bare shell to someone and get a bit of money back

My 84 A+ went straight onto a dry suspension subframe. No drilling, no farting.

Two choices...front cut or diy engine kit.
Front cut... everything is there... from indicators to injection, dashboard.When it was cut up it was a running car. with warranty
Engine kit... satisfaction that you know you've looked at the inside of your engine and replaced everything. bit more money as you have to buy everything seperately.
All cars produced after 1984 had 8.4"ap brakes, but a lot of japanese cars seem to have 7.5"ap conversions, making it another option in buying a front cut.
As far as 12" wheels goes and rubbing the guards... it all depends on your suspension setup, the lower you go more rubbing. Also look at your castor angle.

Either way it's always a good idea to use adjustable castor rods,
to make wheel alignment correct.
I prefer the mini swivel hub, as this is what the car was designed to use and the geometry is correct
