you could buy a new campus sport bumpers from renault as the new ones do not have the black inserts, however i have yeard to have thes colour coded and the texture taken off them would cost about £200+ you might be able to find one in your cars colour unless you are me as the clio campus, whats that a MK2 ph4 or somthing had a resticted pallette and does not come in aswide a rnage of colours as the other ph2's like my flame red.
however i have noticed that renault seemed to make it standard for the end of the clio runn, before it became the clio campus, base model that it make colour coded bumpers and side strips standard ont he dynamique and on the basic campus.
i dunno why but i kinda like mine un coded the only prob is one side of my 54 plate? the plasics have faded slighty so i need to constantly lay on the bumper sine. to make them match.
