My Rota's came w/ Kyokugen 7 sides lugs, but they didn't look like the ones in your picture. Mine were hollow, i.e. you could see thru them like a regular nut, not like the capped nuts you guys have. The key however looked identicle to the key in both the pictures your guys posted.

I had my tires balanced at a shop and the guy used a impact wrench on 'em... but the shop later claimed they always do that, but it's set to a really low torque level, and they torque 'em with a wrench.

Either way, I was trying to put my race tires on in Sac, and the stupid key rounded out trying to get the lugs off! When I got back to Reno, I went to the shop and complained about the impact wrench I saw the guy use. The manager was cool about it, and even after he explained that they never torque with the air gun, he had someone pound some smaller sockets on the stuck lugs and wrench 'em off. Then he hooked me up with a nice beefy set of 6 sided (20mm!) lugs. These bad boys are massive!

So unfortunately, my lugs aren't "locking" or some crazy 7 sides lugs... but then again, my rims are only $120 bucks each, and not a set of SSRs or anything. Plus they're a crazy Subaru offset that will really only fit on another Subaru, so I'm not too worried about some punk kids trying to gank 'em.

To be honest, those keys are pretty soft steel... so I don't trust 'em. If they came with a full on drop-forged stainless steel key that fit my socket 1/2" socket wrench, then I'd consider getting 'em.
