Cadillac CTS-V - CTS-V shocks

I was trying to find if anybody made anything and I cant find anything. I was wondering if the shocks could cross reference with anything like maybe the vettes(unlikely)or just anything. It sure would be nice to put some penske or motons on there.

yeah I saw those just a little while ago. Would rather have a fully adjustable coilover though.
