evening all,

 

Im looking for a bit of feedback from mini owners running rosepetal alloys on their cars without flares.

From my observation Appendix J cars are pre-64 and as such are without flares.

I'm looking into fitting the 4.5x10 alloys onto a car currently running half spaced (not the full thickness Cooper S) rear drums and LP883 Dunlop Cooper S 4.5" steel rims.

Assuming the petals follow the 4.5" width they should fit but by how much clear on the trailing arms and poking out of the arch is the question?

much appreciate if anyone can help with some experience.

Regards MG.

I presume you mean Minilite/ Superlite style rims? If so with Superlites at least  they fit under std guards with 145x10s though the 'bag' of the tryre is effectively outside the body. Most Nb Nc cars use Cooper S flares AFAIK.

I have ever only fitted up one set on a car which was a bitsa disc front sliding window early Mini.

The backspace on the Superlite is 99mm.

I have sold rims only in 12 & 13" for Mini in 12x5 with 90mm b/s and 13x6 with 101. I know you cannot go in further than that.

Performance no longer manufacture them [ or anything] though I do know where some are.

IF others require 15" sizing contact me as I sell them. There is a new supplier. 13 &15" sizes will come later.

At this point forget 10, 12 & 14" sizes.

The best place to ask would be the Ausmini forum http://www.ausmini.c...orums/index.php

He means the replica of the Cooper alloy wheels known as Rose petals and not the replica Minilite wheels.
Nb cars can't run flares.

Have a look here: www.theminiforum.co.uk

 

There's a couple of guys who used to, or still, race in those series- they should know.

The Rose Petal replicas I've seen are 4.75" x 10".
People like Nick Swift use them on Appendix K Minis.
Apparently they machine the back face down to reduce the track to meet the regulations.
 
Mini Spares say the following:

"Rose Petal" 4.75" x 10" alloy- A faithful reproduction of the classic 1960's wheel produced with Swiftune for the FIA Historic racers from our own tooling and suitable for road cars when fitted with spacers supplied. Made with the correct offset for Cooper S disc brakes and supplied with the correct open-ended stainless steel nuts and washers.

Need to be checked for clearance on the caliper bleed nipples when used on Historics Racers less spacer.

Finished in matt black with silver centre and outer rim as orinal. Our wheel is the type currently being used by Historic racers.

BEWARE there is a cheaper copy version on sale but does not fit correctly to the Historic racers and is a shiny black wheel. Each wheel is supplied with a wheel spacer and 2 sets of nuts, for use with or without spacer.

When using without spacers as per FIA cars the disc and caliper will have to be modified slightly.

[Mini63]

Thanks for the responses.

I cant confirm the actual width as being 4.75" or 4.5" plus a 1/4" spacer.

I'm checking with Minispares in the UK and Midlands to confirm.

I don't have or want flares as my car is 1963. Its for road use so the Appendix regs are irrelevant but I was more or less fishing to see what rear drums the Nb/J or K owners use.

From previous experience with similar setups, it's the shocker that rubs and not the trailing arm.

Cooper S had flares factory. Mini Cooper did not.

Nb cars use standard dimension drums.

I used to sell new Mini Cooper S and they did not come from the factory with flared wheel arches  - they were a Competitions then Special Tuning extra at the time.

[doc knutsen]

Cooper S had flares factory. Mini Cooper did not.

 

The wheel arch flares were a Special Tuning item, and could be ordered. But they were not a standard Cooper S fitment. The only visual differences between a brand new Cooper S and a ditto 998 Cooper, were the badges and the drilled steel wheel rims fitted to the S, in order to clear the different f brakes and r drums.

We're calling in from different parts of the world, so we're finding slight variations according to where and when the car was built. In Australia, the Mark 1 Cooper S was built from August 1965 to April 1969 without wheel flares. The Mark 2 Cooper S was built from May 1969 to July 1971 with wheel flares. Not that any of this is relevant to the original question about rose petal wheels.

There ya go, I thought all but very early Cooper S had flares. I seldom pay much attention to Minis. Though did about 45 years ago!

The ones I raced against defenitly had BIG flares. Sports Sedans Some had BMC engines too!

Just to throw another thing out there to confuse the issue, the Cooper S sold in South Australia were fitted with flares a year or more before the rest of Australia (about late 67 early 68). This meant that the flares were available for production car racing as well.

But group Nb is based on the 1964 British built Cooper S. The Australian Cooper S was introduced in 1965.

[stuartbrs]

Are you running discs or drums on the front? From memory, with my Mini, I had to fit longer wheel studs for the contessa style minilites. Or maybe it was a spacer? To clear the front drum. I couldn't afford discs back then! No problem with the rear on a 4.5 inch wheel. Man, I miss that Mini.

Or the Morris 850 or the Morris Cooper... all with sliding windows!

Rim width is not more than 1" wider than standard for that model. They wouldn't reach the overriding Nb maximum of 6", of course.

I think you missed my point.

[Ray Bell]

It seems, though one cannot be certain, that the OP has a Mini which isn't a Cooper S...

I was just trying to bring the thought to that line.

[elansprint72]

There was a lengthy thread on Mini Cooper alloys on here a couple of years ago- of course I can't find it using the search function!

 

There were lots of photos and info on the different types of wheels used in period and what is available today, including the current Cooper (replica?) wheel manufacturer. I can't recall the name but I know they are damned expensive and I seem to remember that they are made from the original tooling.

[Morris S]

Blimey this thread meanders abit!  None of the replica 10" rosepetals available (from either Minisparfes or MWS) require flares and come with spacers to use on non S set ups.

[275 GTB-4]

and depending on where you are, the spacers may not be legal...

[GMACKIE]

Didn't flares go out of fashion many years ago...or should I start wearing mine again ?
