Hi All, can anyone tell me how you id a Cooper body. Not Cooper S but a Cooper. Compliance plate, body # stamped some where etc.

Whats are the sure fire signs in terms of what is or isn't done to the body that ids it as a Cooper?

Have you read John Parnell's "Original Mini Cooper and S" book?

It is full of good tips. I read it 4 years ago so don't remember enough to advise you sorry!

No cut-outs on the front valence, sliding window doors, 997/998 engine.

Don't get sucked into beleiving it had that brake intesifier thingy, it's not necessarily so unless it was imported as a whole car.

Disc brake pedal also helps a little (It's thicker than a standard one), if the stainless trim is gone from around the sliding window doors, it will have special pop rivets with saucer like heads to retain the trim, or at least the holes that were there when the rivets were.

Also three piece per side stainless steel arch trims. These are very difficult to find outside of the UK.

Boot board brackets rivetted in to the boot.

And it should have the little Cooper 7" disc brakes. These used a drive flange very similar design to the drum brake ones, with the wheel bearings mounted on it and a drum brake CV.
Most 997s had postage stamp-sized pads held in with a spring clip and 2 split pins. Late 997 and all 998 Coopers had square shaped ones (like an S but smaller) which were retained only by the 2 split pins..
It is possible to mill out the early calipers to take the bigger 998 pads (I've done it).

The hydraulic intensifier thingy on the RH inner guard (a double diameter piston in a stepped bore cylinder) was used on 997s, the 998s got a smaller bore (5/8") master cylinder which increased line pressure and made the `intensifier' redundant.

I read a cooper has 7inch and not 7.4 discs. Is this true?

Is this the chrome trim you mean around outside of the window?



On the bottom left of this picture is this the boot bracket?

Yes a Cooper has 7", they never got the 7.5s but lots have been fitted since. Not a cheap swap, only the swivel hub is kept- the rest is all changed from CV on out.
Yes that is the right chrome trim on the windows.

How bad are the cooper breaks its been fitted with a 1275? Can you add a brake booster?

Brakes get nicer with a booster, brake fade used to come on reeeeeeaaaalll fast though if you tried a little spirited driving.
If you can find a cv, disc, flange and calipers you can use the hub to convert them to Cooper S 7.5 inch discs.

I had a nice one in Shadow Blue and Nurnburg White just like the smoke grey one above. It had a 1275 until I refitted a 998 Cooper engine and it also had the 7 inch discs with the early lockheed booster fitted.

Original wheels were standard mini rims though. Not the Cooper S ones shown above, not terribly exciting so I fitted S rims and hubcaps.

I put a set of 7" Cooper discs on my bitsa 75 Clubby 998 automatic, with a VH44 booster and metal 998 pads it stopped pretty damned well.
Don't forget, they used to race and rally Coopers with these brakes, they were not as bad as some people make out.
But new rotors are dear now, and they are only 1/4" thick when new.
