Mod the hell out of it. I'm sure you'll forget about your CTS-V aspirations quickly. Do you want Recaro's because they come in the CTS-V? There are plenty of other seats you can get and of course you can always customize them. RotTec makes 997GT2 seats (that recline) for a pretty great price and it has plenty of options. Hit them up, may be worth considering. You can get OEM 997 Sports seats (made by Recaro) for a pretty good price. Or Z4M seats that are way more sporty, lightweight, have more grip, than what you have no but have plenty of comforts.
