im in the process of buying wheel spacers.....i was thinking of 20mm in the back and 15mm in the front...does that sound right...i dont want to push them too far out so it rubs the fender....anyone have this setup..my car is also dropped with teins and kyb so please let me know if im making the right choice before i order....thank you

 

all depends on the offset and width of your current wheels

 

the rims is 18x7.5 and offset is 45....

 

That sounds about right. I tried to fit 25mm in the back and there was very slight rub. This is when I test fitted 25mm ones in the back. So I think 20mm ones will be perfect. FYI, my wheels are 18x7.5 with 47mm offset.
