To get a set like a Trophy then you need to use these part numbers, though I can't confirm accurate as I got them from ClioSport.
2 x 265000575 - Sport Trendline with belt guides, Ambla-Leather black / Dinamica Suede black. £545.00 each+vat
2 x 7201710 - Universal resistor kit for side airbag replacement £20.00 each+vat
1 x 686819A - Mounting frame - Renault Clio ‘98-05, left hand side £114.00+vat
1 x 686829A - Mounting frame - Renault Clio ‘98-05, right hand side £114.00+vat
Total: £1358.00+vat
But as an alternative, you can get the seats from a Honda Civic Type R EP3 in red/black which I like the look of and maybe just maybe if i didn't have the 182 rear bench i would consider buying a set just to see what they looked like as a pair went for only £300 last week on ebay. Though most are about £4-500 it seems. Or the 30Th anniversary ones are all red. Other cars use the same seat like Accord Type R and some EVO's etc but as those are 4 door cars I don't think they tilt forward to let passengers in the back which may be an issue as only alternative is to slide seat forward and wind it forward, time consuming if you use the rear a lot. But as with all Recaro's will fit on correct seat mounts so you could save money trying to get 2nd hand seats and buying new frames etc
Or another alternative is the Recaro Speed as found in my Lancia integrale EVO, and of course in integra Type R's some Civic type R's, EVO's, Celica GT4's etc etc arguably a better more supportive seat but cheaper http://www.capitalseating.co.uk/product ... id=59&rid=
