Original bumpers are like rocking horse poop at present. However, RT-Performance (traders on here) are currently in the process of making replicas from an original they have, I had an update from them a few days ago saying the fit is perfect, they're just designing the brackets for the washer jets - it's worth noting that most replicas don't support washer jets which will be an MOT failure with the new changes. Also avoid the replicas on e-bay - most don't even remotely fit.
I'd recommend waiting a week or 2 for RT-P's replica.... I am.
