For all of you desiring to run Mini wheels on the Fit, here's the part you need for lug nuts:

Part number: Gorilla #41138ET
Specs: Gorilla® 12mm x 1.5 ET (extended thread) w/60° Taper Seat Right Hand Thread

There have been quite a few posts about putting Mini wheels on the Fit, but I've yet to find one providing a part number or detailed specs on the lug nuts. I have seen some posts saying "just use a tapered nut", but I would caution against using anything except an extended thread nut per below.

I just got a set of Mini wheels for my car and these are the wheel nuts I used because:

1. they are a closed "acorn" style lug (rather than open lug, where you can see the stud), and thus keep weather out of the stud and look nicer.
2. these lug nuts have the same 60 degree taper that Mini rims have (which Honda lugs/wheels don't use)
3. Since Mini uses a 14mm wheel bolt rather than a 12mm wheel stud, the extended taper of these lug nuts goes all the way into the mini rim's bolt holes, and the Honda's 12mm studs fit nicely into these nuts and fit great. I strongly recommend NOT using a wheel nut without the extended threads, as such nuts do NOT go into the wheel's bolt holes and thus you risk not getting enough threads engaged... you only engage the threads sticking out of the wheel bolt holes. With the extended threads, you get all the threads = SAFER.
4. At 1.4" long, this particular nut is the shortest closed end acorn-style nut I could find (shorter by ~1/3" from many other, similar spec'd nuts out there), allowing the nut to sit "in" the rim as much as possible, whereas the longer ~1.75" nuts just seem to stick out of the wheel too far and look funky.

4x100 Mini wheels fit perfectly: same 56.1 center bore and 4x100 bolt pattern. You just need the proper wheel nuts.

Hope this helps!

 

There are a couple of those threads that still list valid lug nut part numbers but most of which the part number has been superseded or the lug nut is discontinued all together. Still haven't a more recent and up to date thread doesn't hurt in my book.

The big thing to remember is what gen of MINI you're sourcing the wheels from.

R56/R57 Cooper (whatever chassis code, period correct Clubman) wheels feature holes for the 14mm wheel studs like the extremely common 16x6.5 "Bridge Spoke" on the pre face lift R56/R57 Cooper hatches. So your lug nut is definitely appropriate here and also exactly what I'm running on my beater GD with R56 Bridge Spokes as well.

On the older R50/R53 Cooper (like used in The Italian Job remake) however, those12mm studs and can be secured with a normal M12x1.5 tapered seat nut.

 

Good to know for those looking for R50/53 wheels! I'm running R81 7-hole 15x5.5 wheels from the 1st gen early-mid 2000's Coopers.
