wheel offset
 

I was wondering if anyone could provide insight on what will/ won't work as far as offset. I am currently doing an svo 5 lug /disc brake conversion on my 87gt. I am planning on purchasing new 18x8 konig wheels. I noticed that a set of wheels (konig villians) my buddy has on his 91 (which also has the 5 lug conversion) have a 36mm offset........the wheels I would like to purchase (Konig tantrums) have a 40mm offset. They are unavailable in a 36mm offset. So I would appreciate any input as far as maximum/minimum offset is concerned.
Thanks, Scott
