I am fitting 4.5 x 10 cooper inverse wheels and will also be fitting 4.5/5 x 10 GB alloys in winter with winter tyres. I am not fitting arches to the mini so need these wheels to fit under the wings to pass an MOT and not look stupid.

I am going to be fitting the later hubs with 8.4" discs milled down to 7.9" with mini sport 4 pots. will this set up keep the wheels within the wings? or is a cooper s set up needed ( i dont really want to have to revert to this i have build up hubs and disc etc...)

Also on the rear will i fit spacered or non spacered drums to keep the wheels where i want them?

Any advice appreciated,

Thanks

Daniel

the calipers will be too large as there are four pots, although some people grind off parts of the caliper. the cooperS setup will fit hopefully as it was made for 10's

I think by MiniSport 4 pots he means the alloy calipers.

Not sure what the offsets are of the two disc assemblies, but I believe both maybe the same, and so with 4.5 S reverse rims you shoud be ok.

I know that when I went from my Cooper S assembley, to a 8.4" set, machined down to 7.9" with KAD 4 pots, the track of the car stayed the same.

plus I dont think those minisport 4 pots fit under GB's

[daniel_johno]

i thougth that the disc brake set up had a wider track than the earlier drum brake set up which is why the rear drums where spacered on later cars?

I can get the minisport 4pot alloy caliper set up using 7.9 discs for about the same price as converting to 7.5 cooper s items, so thought this would be a better choice the braking potential is greater and they look alot nicer.

Thanks for the responses

I have 7.5" 4 pots, and have fitted all sorts of rims over the top, but with 7.9's you're going to be limited...

I've fitted reverse S rims over disks and have been lucky to get away with it, they stick out about an inch and it's not an MOT issue, having your wheels sticking out, as it does not form part of the test... it's a legal one, ie the police can stop you and give you a fixed penalty there and then.

Ok thanks for that.

Final question, Do i fit spacered or non spacered drums?

Thanks

with the extra track at the front from the disc's it would be beneficial if you fitted the spacered drums to keep your handling sharp!

Ok this is def my final question on the matter......

I think it will be benefical for ease of fitting all kinds of 10inch wheels to fit 7.5" discs and the matching flanges. Ill later decide on either the standard 7.5" calipers or go over kill and get some sexy Alloy 4pots.

Would the fitment of the 7.5" discs and flanges decrease the track width of the wheels or was it just the drum brakes that had the narrow track. (again im unsure of spacered or unspacered drums for the rear with the 7.5" brakes)

Thanks

7.5's will still make wheels stand proud of the arches. And you will still need spacered rear drums if you fit 7.5's at the front.

I thought Cooper S reverse rims had the offset that allowed you to have disc brakes without the need for arches?

Thats what i thought but also thought the 7.5" brakes sat further in than 8.4" set up but i was wrong about that also.

Tim Mundy in this months mini world answered a question about tyre sizes and said the 165 x 10 tyre aparently sits outwidth the wings but the 145 x 10 tyre sits within the wing.

Anyone else heard of this?

The 1980's/90's minis with 145's fitted as standard all had arches fitted as standard too due to them falling outside the wheel arches.

[Jordie]

My 1984 mayfair running standard minilites with 145 rubber just stays inside the lip of the wing.

I am running 8.4" discs, so spacered rears as standard.

The tyre size hasn't really got anything to do with where it sits within the arch, the real important factor is the offset of the wheel! You need something with a large positive offset.
