I got my Turini's from speedline direct. £499 delivered in any of the colours in 16". ET 40 is the standard aftermarket size of these.
Not sure if the Trophy turini's will fit the satndard 182/182 cup packs because the trophy uses different hubs doesnt it? I bought trophy wheel centres for my turinis and they are smaller in diameter that the hole in the wheel, therefore dont clip in! easily fixed with a bit of double sided foam around the clips on the centres though
As for the spoiler, i was quoted around £220 + vat from renault originally, but waited ages so got it a bit cheaper
Hope this helps some
If you need the part number for the spoiler, just let me know!
