how well of how bad would such a system be.

these would be drum brake type and would never have any more than about 60hp in the seven i would be building

well, there are plenty of hubs out there that will work as well.

But, the mini hubs will work, and will take probably twice the amount of horse power you are going to use easily.
They can be mounted upside down aswell, to aid the connection of the "top" wishbone.

You can also then use the steering control arm as a "fixed to the chassis mounting point" on a short bar with a rose joint in the end to facilitate toe in/out adjustment!

GTMs used mini front hubs on the rear way back in the sixties, not sure how the handbrake worked ?

i have 2 sets of them so just got me thinking as they have a are pretty simple

for the handbrake i was thinking of simply using the rear brake plate of a mini on the front hub

when say mounted up side down what exactly do you mean by that? do they work better for camber changes when upside down or what?

Trick to the handbrake is to use the pre84 drum hubs and the backplate from the rear of a mini.
You need to re-drill and use a hole saw to cut a hole for the driveshaft.

I have some modified backplates for my buggy that were modified by the manufacturer. I can take some pictures on Friday and post them if you are interested, but it's straightforward (in theory) if you have them in front of you.

Alternatively you can retain the disks and use a handbraked caliper with a suitable bracket. I've seen sierra rear calipers used on the mini hubs to do this.

Better to use Metro disk braked hubs with Rover 200/400 rear calipers - bolt straight on.

With a middy you need almost 50-50 brake distribution in the dry so don't be tempted to under brake the rear or you end up with car that is horrible to drive especially in the wet and more importantly won't stop no matter how hard you push the pedal.

Take a look at the brakes and front & rear suspension of the MGF/MGTF --- nearly all Metro parts.

Other problem with using front suspension parts at the rear is the need to avoid bump/roll steer.

yea would be useful maybe to see a pic of the back plate if you can do it with out too much bother

personally im thinking of doing this on a 7 type with the engine up front, just trying to work out whats the best way to build a car with the bits i have
