Vented Disc Question
Turbo Mini Forums

My metros got solid discs which are a bit worn out so i was thinking rather than replace them with another set of solids i should take the oppertunity to convert to vented.

I allready have a set of calipers from a mk2 metro with vented discs but i hear mini people talk of 'vented drive flanges' do they just mean metro ones in general (as oppose to mini ones) or are vented drive flanges differant to non vented on the metro aswell?

vented ones are different, If you bolt it together with your existing flanges the disc's will foul the hub.

also the vented flanges will move the wheel outward a bit, .6" I think.

you can tell the vented flanges as the cv nut washer thing appears recesed below the face that the wheel bolts to.

The vented flanges are thinner.

yep, when i changed them on the mini the drive flange for the vented discs had a smaller diameter.

ive had my moneys worth out of this pic LOL

Isn't that a pic of a mini flange and a metro flange,
really we need to see both types of metro flange as this is a metro fitment.

heres a pic of an up rated minispares vented metro flange which comes with no lugs, and is a smaller diameter, but it does show the recesed centre i mentioned.

yeah, a std mini vs std metro vented flange

that uprated one in your pic (presumably the same as the ones you sent me?) are basically the same as the thin flange in the above pic, but the edge isnt tapered to a thin outer section.

Oh yeah forgot you had those,

from the pic i wondered if they were the non vented metro ones so i bunged up that pic to show the face.

I'm sure minispares used to sell std metro non vented flanges AND std metro vented flanges, they only appear to have the uprated modded metro flange now, NAM ????F.

They are different as stated. Might be worth a call to Min-Its as the last time I checked they were significantly the cheapest supplier I could find....

Every day is a school day ...........

How fast and how expensive ...... the same question...

yeah, thanks for those, you got me out of a fix.

basically the way I think about it is.....deep breath...

....when they developed 'wider' vented discs, they couldnt move the inner edge of the disc closer in as it would foul the hub/sterring arm etc, so the used a 'thinner' flange to 'pull' the disc out further (and central in the caliper).

I say 'thinner' and not thinner, because like you say on the 'uprated ones' all they did was recess the chamfer where the hub nut washer sits, effectively pulling the whole assembly out, and spacing the wheel out further.

i might be wrong but it all makes sense in my head.

off to bed :)

Yes thats it!

cheers guys, will have to head down to the local 'metro breakers' and get some vented flanges!

Hopefully it wont cause any wheel rubbing issues! Do you think it would be possible to m/c the non vented flanges to move the disc out but not the wheel??

You'll be able to take a bit off, but I higly doubt all of it,

The fronts don't normally suffer from rubbing, even with wheels without the metro inset, I had a set of 12" imp cosmics on and even slammed onto the bumpstops they cleared, in fact the inner cv's were getting close to poping out from the sound of it.
