i think it's fair to say yours and the peugeot OEM wheels especially in white are a classic style, that i'd very much contemplate if Duffy wouldn't beat me down for copying him aha!
but good choice on the white and especially the 17's because the 208 has big arches that dwarf my 16s with the huge tires on them.
the only other alloys i've thought about recently are some OEM style citroen ds3's just for the why nots
I'd recommend the springs, they improved my car greatly in terms of stiffness, but it's a slippery slope because i'm now interested in coilovers
i'm intrigued where the touch screen hack goes
