Personally, I would not buy any seat that is non-Recaro without sitting in it first. IMO, anybody who buys a seat without the ol' buttocks taking a test drive is including a good amount of risk in the equation. The better the seats, the less risk ... but likely the more money to be lost if things turn south. My suggestion is find a seat (eBay or otherwise) with a money-back guarantee along with a high feedback rating. Buy a SINGLE seat. If you like it, install it. If after driving with it for a while you STILL like it, then get the other to complete the pair. If you are not happy initially, send it back being happy that it only costed you the shipping charges to find out. Is this any help to you? Likely "no" ... sorry for that ...
Also, what about some Corbeau GTS II's? They are in the same price range and you get a name (albeit not at a Recaro) that you at least recognize. Justa thought...
