Fronts will be 20x9 and i have a choice of +15, +25, or +35 for the offset. Which should i choose.

Should I run 20x10 in the rear or 20x11? Both have offset choices of +15, +25, +35 as well.

 

All depends on how much your lowered and what tire sizes you will use.

 

Going for a slammed or tire tucked look. Not sure what tires im running yet.

 

coupe or sedan?

I would run 20x9 +25 and 20x10 +25. This should give you a pretty standard flush fitment with 245/35 and 275/30 tires. But it all depends on how low you drop your car. What wheels are they? Make sure they will clear your akenobos.

I guess you can use +25 as the reference point. If you want to run wider tires and tuck, then run +35. If you want a more stanced out look with stretched tires, then +15.
