I bought the Corbeau forza seats very cheap 180 for the pair and 50 quid for the subframes, I was quoted 95 quid for the golf frame from the company I bought the seats from not tried them yet, they are still boxed, I got the harness'es from a chap off this forum
I have recently got some Cobra Monaco S, got them off ebay, brand new, 195 for the pair, delivered. They fit nice for me, I'm quite a skinny guy. The subframes are 50 each though, so I made my own.
