Hi mate,
Recaro seats came as standard on 'Limited Edition' and 'Turbo Plus' style coops, but these are lots rarer than a bog standard 20vt, also a lot more expensive, can put 2 grand on the asking price.
I run Bilstein sport suspension and Eibach springs on mine. Cost me 450 and 100 GBP pounds respectivly and really firms up the ride.
I have also heard that a strut brace can improve handling by reducing understeer considerably, and is top of my wish list at the mo, expect to pay around a ton for one. (though they also come as standard on the special edition models mentioned above)
