Should I go with to get flush with my fenders. I was thinking either 15 or 20mm. My rim specs are:
19x8.5 +28
19x10 +43

Thanks for your help!

 

I would use 15mm front and 20-25mm rear. If you are only going to use 15mm make sure the back of the wheel has grooves in the back pad because your original bolts are longer than 15mm and will still stick out past the spacer. Also make sure the nuts you use to bolt on the spacers are short.

 

Thanks again for ur help Yakuza! I was actually considering the same thing 15mm in front and proly 20 in the back so this helps confirm.
