How do I make them fit?
 

Hey guys, I am almost finished with my front and rear LS1 brake conversion
And I saw a set of nice ass set of 19" 5 spoke rims. The info on the rims is that
They are 19x8.5 bolt pattern is 5x120 and the offset is 20. Now I don't know
About a wheel offset so I don't know if it having a offset of 20 means that it
Won't fit or not so that's why I'm coming to you fellas. Somebody help me....
PLEASE?

Make them fit what? 20 mm offset (assuming it's 20 mm positive) would be about the same as 5" backspace.

Yeah the offset is 20mm. I will check to see if 20mm positive or 20mm negative.

Not trying to sound like Im brushing you off but take a good read here.

There are really some very good tech articles that will help you with the overall tire and wheel fitment issues. Including the nomenclature used when dealing with wheels and tires. Some great info..

For your Q. The 20 you say is what, 20mm. Pos or neg? Read the offset tech blurb. http://www.tirerack.com/wheels/tech/...jsp?techid=101 and it may help. JR
