OEM Lug Nuts

[Wassabi]

I wanted to try my 951 S in a PCA DE this coming season and would like to start preparing myself and the car. I seem to be coming along just fine until I went to order a set of steel lug nuts for my car and noticed 2 different seat styles available here at pelican. I was going to order the set of 20 Rennline, but saw they come in both BALL SEAT and CONICAL SEAT. Since I've put my car away for the winter I cannot easily go and check, but from bleeding the brakes last summer I think I remember them being ball seat, though I can't be sure. As the car is completely stock I wanted to know what the factory seat is on my rims to order the correct set of lug nuts.

Thanks in advance,
Alex
