As a recent new owner of a set of Recaros, I will say though expensive, well worth the investment. The before and after is like a whole different car. I put larger front tires on this year and the Recaros, I'll put money down that says the seats will be a bigger improvement than the extra 20mm/side of rubber.
I knew it would be better than the WS6 Trans Am seats (decent oem bolstered seats too), but I had no idea how much.
