non-sport offset question

[ksixx]

sorry if this has been asked before but had alook on the search and couldnt find exactly wot i was looking for so here it goes totally standard clio.

found a set of laguna sport alloys (16inch) look a wee bit different to the normal clio alloys and was wondering if they would fit
offsets apprently 50 and the rim width is 6.5j

would i need spacers and longer bolts or what would be best ?

thanks k,smith
