What do members mean when they say "aggresive offset"?

I'm looking into getting some wheels this xmas. but i dont really understand offsets.

wheels that im trying to get is Volks Diamond Black. 19x9.5 front and 19x10.5
i want the flush look. i dont want the tucked in look at all. which offsets should i get? TIA

 

agressive offsets for the coupe would be anything under +20, the closer to 0 you get the more agressive or bigger the lip will be. If you want the flushed look with 9.5/10.5 i'd go for 23-28 all around.

can you please clarify on what u meant on "23-28 all around". sorry, im really new at this. 23-28 offset?

 

ths is a guide. put in the measurements and different offsets and it will tell you how much farther in or out the lip will sit.

thanks Raw

 

Yes, that's what i meant. 23mm-28mm offset on all the rims. My friend just got 23mm all around on a 9.5/10.5 set up and it looks perfect.
