MX5 NC 2.0 Sport
Nice one smokey the proof will be when the scenic disks go on and then you will know for sure.
How does the thickness of the scenic disks you plan on fitting compare to disks fitted standard on the espace.
Have you tried checking what other variants the calipers come on, you might find them on a another sport model and more than likely there will be better pads offered which would be a win win ( I realise your not interested in peak performance for yourself)
The scenic/172/182 discs are 24mm and the discs from the espace are 28mm.
I haven't found any other variants, and don't see the point searching for some other models. The Renault Sport models are allot rarer here that they are in the UK so spare parts are rather expensive (wich spoils the point). In my opinion you should just go with the 197/225 calipers if you want peak performance.
