Locking Wheel Nuts

[bss1978]

I've just bought an 54 plate A4 Avant 1.9 TDI sport...it's got 17inch 5 spoke alloys on with the audi emblem in the middle so I assume they're the original alloys.

Problem is there's no locking nuts on them. I'm looking to buy a set and have been looking on ebay but I'm loathed to order a set without knowing I've got the right ones first. Am I right in thinking that I need a set that have got a 'radius seat'??

I took a nut off today and it's got a 'rounded' seat....is there anything else I need to consider??

Thanks

Just pop along to an Audi dealer. They sell the Audi packaged McGard type for the same or less than the Ebay ripoff artists. You also get plastic caps and a removal tool. My dealer kindly remove the old type locking nuts with the master set, FOC as the car didn't come with the master socket.
