UK-POLOS.NET - THE VW Polo Forum

Bought some preowned 17" alloys for my polo but didn't come with the bolts. I know I can't use the existing ones so how do I know what to order? Obviously I know the 5x100 setup but is there a specific thread or length bolt I need?

As they're Wolfrace Katana's, have you asked Wolfrace? They ought to be able to help, and I'd have thought they'll be able to supply you with a set that have the correct profile seating face to fit the bolt holes in your wheels.

You may not get the answer from the forum, unless a forum member has the same wheels on their car.

bascially, you'll be having two types of wheel bolts that should NOT EVER be mixed up.

you have the simple cones. the side looks straight. like a traffic cone on a stick.
and the spherical heads. they look like half a ball on a stick.



a rule of thumb is:
OEM rims have spherical bolts
aftermarket rims have cones.

I've checked with the manufacturer and they say I'll need a 60 degree tapered bolt but looking at the wheels themselves, the seating looks very much like the sphere shaped bolts rather than a flat surface. I even tried my existing bolts with the radiused heads and they fit fine.
