I've got a Sparco EVO L in my '06. It is excellent for track work and is comfortable for day to day driving including long trips....and I am a big bloke too.
It did take a lot of stuffing around to mount it low enough on sliders...I used the side mount STI RSR Recaro frame which was then modified by MMS.

My advice is to go and test sit as many seats as you can...eg at Revolution Racegear, Go Gear etc...

When you mount it, the trick is to get it nice & low. You can test sit mine if you want.
