Konig Holes on an S13 Zenki???

[Project RPS13]

Okay, I had my mind set on a set of 17" 5zigen typhoons (atleast 8" wide and probably a +35 offset) but a cousin of mine has offered to sell me his Konig Holes for next to nothing. I guess Konigs are alright and i believe they are about 3lbs lighter than the 5zigen typhoons but the problem is that they are 17x7 with a +45 offset. How big of a spacer would i need to get these wheels just about flush with the fender? ... or should i not even consider these rims?

any comments and opinions on konig holes are also welcome.

Thanks!!!
