spend the extra money and get the Sparcos. I've had my Corbeaus for about a year, and am upgrading to Sparco Milano2 seats in a month or so. Their quality is much better than Corbeau. For intro seats, they are good, but once you start spending around $500/seat, go for the Sparcos. Just my opinion
the Sparcos are definitely more comfortable than the Corbeaus. Ive sat in both. If you want to get something a little different from the Torino, but in the same price range, take a look at the Sparco Monza. They have a mesh in the center for better breathing, kinda like what you were talking about. They dont make them anymore as of this year, but a lot of places still have them.
they are a little more expensive, but they have the better microsuede than Corbeau. If you plan on keeping the car for a while, spend the money on what you want, rather than cheap out by $100/seat and regret it everytime you sit in your car. Trust me, thats why Im getting the Milanos.
