So I just picked up a set of 5x114.3 Bbs rs the center bore size I believe is 68mm where as the s2000 has a 70.3 has anyone mounted the same set up of wheels and how did you get around the smaller centre bore of the wheels being that it's only a 2.3mm difference

 

You can usually run a small 5mm spacer to deal with the hub issue. You could also get the wheels bored out but that is more difficult.

 

With a 5 mill would I need longer wheel studs or am I still safe

 

5mm is the max spacer you can run without longer studs.
