hi all i am gust wondering if it is possible to fit mg-tf wheels to my 1987 mini city
the wheels are 6 inch by 15 inch. i know there will be some butchery of the wheel archers and wings but thats all i know. thanks for reading.

You need to work out the PCD and the offset..

15" don't fit in the radius arms, mgf hubs are different pcd too

[Cooperman]

To make a 15" wheel fit it would need a 4" PCD, not a metric figure.
Additionally, to get the rolling radius right so that it would fit inside the rear radius arms you would need a tyre with a wall depth of about 2" which would mean a 175/35 x 15" tyre (can you get that size?).

There was a mini at the mouth to mouth run with MgF wheels, engine and lots of other parts

Terry's is just a mini shell dropped on top of an mgf

They won't physically fit on the Mini wheel studs as the MGF (and TF) use the old Triumph standard of 3 3/4" PCD as opposed to the Mini's 4".

It's possible to overcome that by modifying hubs or wheels but then you'll run into problems with such a big wheel hitting things like suspension and bodywork as other people here mention.

With enough work (or money to get other people to do the work) anything is possible but to be honest if you have to ask this sort of question then you don't have the necessary knowledge to do it yourself so you would need to be in the category of people who can just wave a cheque book over their car at a specialist and say "fit those" - those people are not so likely to be here asking questions about whether this or that will fit.

Thanks for the advice and as for ians post i will be doing all the work my self using metro hubs and maybe a rear beam axle

[tiger99]

I suggest that you check what a beam axle actually is before deciding to fit one! It will utterly ruin the handling, and will cause massive complications with the spare wheel well, battery box and exhaust.

I assume that you really want a simple crossmember (why do people not just call it a crossmember, it is not a beam axle, or even an axle beam?) to mount the radius arms, instead of a full subframe. That in iteself brings many problems, for road use at least, as it implies using coilovers, which loses the critical property of the rubber cones of having a rapidly rising spring rate. It may well be good for track use, but that is all, as significant changes in vehicle load, such as having a full set of passengers, can not be accomodated with simple coil springs, even those which are variable rate. And, you need to strengthen the damper turrets, and I am far from convinced that it is safe to carry both spring and damper loads on the stub axle inboard extension.

Personally I would not bother. Issigonis got the suspension design right, and it works well.

[LTSwaby]

i mean what i said, it will be a metal tube mounted with coilover shok absorbers and and two swinging arms mounted to where the front rear sumframe mounts are. no radius arms or any thing else just three tubes one that has the hubs on that will also be mounted to the suspention and then the two swinging ones that mount it to the body shell

Metro hubs are 3 3/4" PCD - so you could use them......to carry MGF wheels. But really - is this a sensible project ??

If I've read this right, the OP has some second hand wheels that are worth maybe £50 each and so he's going to completely chop up his Mini that's worth maybe £2000 to fit them!

The engineering sounds unfeasible to begin with. It will demand very considerable technical skill - or a very deep pocket. The end result will be mechanically dubious, possibly to the point of being unsafe!

The Mini on 15" wheels will inevitably be a very peculiar thing to drive - almost certainly absolutely horrible - and it will look .... well, different!

So in spite of everyone's advice to the contrary I think it's a great use of the OP's time!!

[tiger99]

Yes, that does sound like a beam axle, and is absolutely guaranteed to ruin the handling. Make sure you tell your insurance company, who are not going to like it.

But your description does not take into account how you are handling lateral location. Two trailing links to the beam axle is not sufficient, by far.
