TSW rims

I found these rim here
http://www.gmpperformance.com/index....PID=86947&VS=1
they has 19x8 ET 20 and 40 front
19x9.5 ET 20 and 35 rear~
If I want to buy them
Should I go with 19x8 ET 40 front, 19x9.5 ET 20 rear
or 19x9.5 ET 35 rear??
I was confused~~
I know that 19x8.5 and 19x9.5 are correct size~
but i don't know the offset~~

40 front/35 rear...for 40mm offset in front, you will have 6mm retract compared to the stock wheels which is not noticeable for the naked eyes.

No, but you could safely go for a net rear offset of 25mm if you want a more aggressive stance (i.e., 35mm - 10mm spacer).

Is it mean the less offset in rear wheels, the stick out in rear wheels?
I thought I never understand what exactly" offset" mean~~

Yes...low offset = stick out. High offset = push in.
