Does anybody know the proper offset for these type of wheels, im looking to purchase 20" Axis Vips, right now i have stock 19". thx in advance for responses.

 

correct offsets will be affected by spoke design

 

define proper, the "proper" offset is a function of desired width, flushness, lip size, brake clearance, alignment settings and tire size

 

Would this work on my coupe: 20x8.5 front and 20x9.5 rear. i believe the coupe is staggered, so this would be correct right?

 

Those wheel sizes will work, but to determine which offset to purchase you need also need to factor in tire size, stock offsets are +30 and +33, and obviously you would want them to sit more flush than stock, so just check around to see what offsets others have gone with the similar wheel/tire sizes.

 

How do I do that?

 

Go to 1010tires.com and use the offset calculator. It'll show you how offset choices with various widths affect clearance and flushness
