I use 10mm in front and 20mm in rear. These are on 03 SE's w/ 235 45 17's.

 

If I had it to do over again I agree with ^ 10mm in front and 20mm in the rear is about perfect flush with the fender. I have 5 and 15 now and really want that extra 5mm

 

back from the dead.

Im running wheels with 25mm offset front and rear. nice flush look on 19"s no problem at all with these offsets. I assume spacers do the same thing as wheels with lower than stock offsets.

Gonna be running SE-R wheels for the winter, I believe they are 45mm offset. so planing on running 15mm in front and 20mm in rear.

 

I have a 2011 Maxima SV with stock 18inch what do you recommend for spacers? stock suspension as well

 

search the 6th gen forum, there is a good rule of thumb that most guys are doing for a ideal stance.

definitely atleast 20mm or 25mm for the rear
