Does 5X100 fit an evo? Or can someone tell me what lug offset does. Sorry for the newb question.

 

Lug pattern for the Evo's are 5x114.3.

 

What is the absolute minimums and maximums for offset and wheel width

 

Search and read. There are a half dozen stuck or top of forum threads on this.

 

Can someone explain to me what does + 30, or +40 mean when talking about wheel offset.

How do I know will it clear the calipers?

 

there are a ton factors to offset....it all depends on wheel type. 0 offset theoretically would be the farthest the rim can sit off the hub. so the bigger number you go would would pull the rim closer towards the hub, if that makes any sense to you.

 

Mess around w/this calculator which will help you gain some understanding how offset affects wheel fitment

WIll this clear the calipers? 18x9.5 +40 5x114.3

 

depends what type of wheel. if they were enkei rpf1's you would need a 25mm spacer.
