Yup there exactly the same seats from the RS clio's and the Clio 'Sport' Dynamique range.
Not all the lower end models have the same "snugged up" seats. I think MOST Dynamique spec and above (Dyn S, extreme? etc)
It will be obvious if they havnt got them, the side bulsters are quite a bit smaller and the seat doesnt look as "buckety"
Be aware that the wiring for the airbags is slightly different and will need adjusting accordingly.
And that even though they are Renault seats, you need to inform insurance of change too.
Hope that helps.
