Super fins

[Luckyun]

Has anyone ever fitted superfin brake drums to a mk3?

[manifold]

yes. mine has them on coupe. just need the longer studs for built in spacer...same as 1275gt

Many thanks, so other than longer studs there is no alteration needed?

Just be careful that they fit in the locating hole in the centre of the wheel, one of mine did and the other didn't! I cracked a wheel, but I cannot quite remember why or how now!!! Old age!!

Sorry the photos don't want to work, click on the link.

As in Alan's photo, minifins with a small spacer will match a standard spacered Metro drum, although I believe some Metro's don't have spacers built in, and I don't think Alan has any spacers.

Super-minifins will probably work OK on standard Metro alloys with a 130 mm C-dimension, but may push the wheel out too far if you have say Revolutions with a C-dimension of 115 mm. Although as David says he's got them on his car.

mine are chinese (I suspect) superfin copies. Only thing I can think of is maybe to use a mini bearing hub carrier, although I used the metro one. Only difference really is that there is 2 drillings on the mini to hold the hub on.

Mini and metro hubs are interchangeable. Metro has the wheel centre locator on. other than that, the same.

That was it the wheel centre locator interfered on one wheel but not the other, I drove to the Moffat event with a wobbly wheel! Then another Midas owner following me noticed, I tried to tighten the wheel, but cracked as it didn't want to go over the wheel locator!
Obviously one wheel centre hole is bigger than the other, so it is the original Midas wheels at fault and not the Minifins, back to cast iron now!

Thank you everyone. I have the revolutions and the cast iron brake drums have built in spacers. I think I'll get some of the cheaper copies and see how it goes!!!!

Get the lathe out Alan and skim the centre locator off. Job done.

Just had to do some thing similar to adapt a trailer hub to 4 studs from 5...as it had a centre locator too big for new wheels. Reason is it was cheaper to buy 2 brand new 8 inch wheels with tyres fitted, than 1x 9inch tyre for my trailer!

From Alan's description the larger centre bore of the wheel isn't machined right through, so would I be correct in saying that because you subsituted spacerless minfins for the spacered Metro drums, the step in the centre of the wheel sat on the end of the centre locator? So all you needed was a slim 5 to 10 mm ish spacer on the drum or if the wheels can stand being further in just the ends of the centre locator lugs grinding/machining off.
