what do i need to fit 114 wheels to my 04sti which i believe is 100pcd is there ant safe way it can be done??

 

I suppose the safest way, but most expense would be o get the hubs off an 05sti. But I think the reason they are different is because of thicker driveshafts. So you'll need those.
I have seen PCD converters before. You bolt them to the hub using the original 100pcd holes, then you have studs come out in the new pattern.
Its most probably not worth the hassle.
