I have gotten the gorilla system wheel locks for all my lugs on my wheels.
When I bought the car the car came with after market cone seat lugs.

It does take a little practice to remove the lugs with speed. I was wondering if there are any good ball seat lugs with standard sockets that are made of steel. I would try to look for OEM, but I figured they may be expensive.

 

Pretty sure gorilla makes ball seat lugs that fit.

 

I bought some off ebay, there are some vendors that sell them there in different lengths and some different colours, which are meant to be used with oem wheels only. I don't recall the vendors but a search there will find a few of them.

Yes, I know about the DPA accessories lug nut. However it doesn't state if it is made of steel.
Only the Gorilla "The System" wheel lock lug nut which i bought for my S2000 does state it is made of steel.
