Need Help With Front Runner Question If is your daily drive, you will feel safe running wider than 3.5 in the front, I have 15x3.5 but doesnt feel very safe man to be honest, and to put something on your car that will be unsafe is not worth it , but is up to you is just an advice, so if you run 3.5 you will need 1.75" backspacing, shank style lug nut 12mm x 1.5 thread size, 1.300 - 1.380 in shank length, and a 0.679 - 0.687 in shank diameter, ARP wheel studs and 5/16" spacers.
You might need to grind a little still.
By the way I never had problems with 15x3.5 fronts but I just hate feeling unsafe everytime I turn or high speeds in the highway
good luck

You need the spacers to help the wheel clear the caliper. You might still have to grind it a little, but not too much. I have the normal wheel studs. I run 15x3.5 prostars all the time on my daily driver. It feels a little weird at first, but you get used to it. Also no more taking turns at 40 mph.
