in my 208 I installed the OEM from 308cc, which is Licancabur 18x8.
That was a pain because its offset is 34 and is too inwards and touch the shock absorber. So I had to add spacers. Started with 5mm and it worked fine to clear from shocks, but when driving and twisting the car chassis, it touched the rear shocks.
So I got hubcentric ones which were 12mm and it got too outwards, touch the wheel arch.
As I had no plan to lower suspension I left that way. I'm trying to sell my Licancaburs to look for another 18 but in this case I would prefer 18x7 and not 18x8 as it will be a problem anyway.
