I've used sparcos, momo, and corbeau's....along with the different stock seats....
First......do you want fixed back seats or adjustable? (Reclining)
If fixed you can find used corbeaus pretty cheap, sparcos too....
Fixed back seats are great for the track, but a bit of a pain in a daily driver.....
I'd try to find a set of used stock 911 seats, decent bolsters.....sport seats have even larger bolsters.....
You could also try to find some vw recaros.....
