Looking to replace my chrome lugs with McGard black lugs but I see two different styles for the C8. I see 'cone seat style' and 'bulge cone seat style'? Are both compatible on standard C8 rims? Is one beneficial over the other?

OK everyone: do NOT park your C8 next to Bucketoy's!!I’ve had both styles on my C8. I have the ones with the “bulge” on them now. The “bulge” is actually a steel ring around the lug nut. I think the idea is, if you whack a socket onto the lug nut, it will just turn with the ring, not the lug nut itself. If they want our rims, they will find a way to take them. My goal is to make mine a little harder to take than the guy beside me![]()
When I see you guys have 2 locks per wheel, I'll have to put 3 onOK everyone: do NOT park your C8 next to Bucketoy's!!

Steel and aluminum have a cathodic propensity to do that. I had to beat the rims off my plow truck with a sledge hammer a couple years ago. They get coated with anti-seize graphite now anywhere they touch now.I had those locks with the ring on my Jeep...had to get them cut off last week to change over to winter rims some guy put them on to tight and they stuck to the rims...oh yeah...that was me...no more wheel locks for me. Even going to take it off the C5 in the spring

That's what I did with them this time...antiseized the crap out of them where they meet the rimSteel and aluminum have a cathodic propensity to do that.
