Anyone know the factory size? Mine were looking a little tired so I ordered new ones. I have the oem 5 spoke 18"s on a 2003 996 C2. The originals are different than any I'd seen before with a sliding type cone seat. The company I ordered from specified 27mm 14x1.5 RH RAD ball seat R14. I have used this company before and they are very good. What I got was a conventional looking lug, one piece. At first they didn't seem to want to thread on and what with them looking so different I called the suppier back. Thay verified the lug size. I tried them again with renewed confidence and found I could thread them on but not really as far as I expected. The overall length of the new ones is shorter. The ball seat does look the same but I'm really wondering. Any info before I call the suppier again?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

For MY01+ if you don't have any spacers the original part number was 996-361-203-01 but that was superceded to 996-361-203-02 in 2004. The head on the newer wheel bolt was shortened to 14.5mm from 16.5mm to save weight/money and the length of the rest of the bolt is 45mm.
