Hi Parisien,
3200 bolts are different to assetto corsa / 4200 / spyder / GS bolts, but to be fair the seller does query this. Those shown in the photo's aren't the same as mine (04 plate 4200), which have shorter faces, below which there is a 'collar band' about 2/3mm deep, however the part number checks out on Eurospares and so I can only think that my bolts may have been superceded by these or that these are chromed options with a slightly different profile? It's a **** good price though, as Eurospares are showing them at £14 a pop!
Maybe you won't be needing the spare set after all?
Cheers, Emtee.
