Only thing is that once you have got over the "feel good" initial period, I'd think that as your car is way down on axle loads when compared with the Cupras, that the spring rating will cause a firmer ride than what you have on. Remember that VAG supplies maybe 4 or 5 "ranges" of road springs - based initially on axle loads - forgetting the ride height "thing" that coil overs avoid you worrying about.
