What wheel bolt pattern does the SS use? Is it the same as the Ion RL?

5x 115mm w/a 42mm offset.

So it's different than the RL? That's odd, eh?

(the RL is 5x110, right?)

I may be wrong, I have looked at a lot of different bolt patterns lately and they get mixed up in my mind. But I know for sure it is the same as any of the midsize GM cars (Malibu, G6, and maybe even the 9-3).
