    My son is buying new wheels for his 2017 Mustang GT. He's running the Eibach Sportline Pro drop springs and is ordering a 20x10 wheel and wants to run 305/30/20's on all four corners. First, would this setup work? Secondly, what offset do you all recommend for the front and rears to ensure no rubbing?

    He does not track the car, and does not want to run spacers.

    Edit: He's ordering the new Vertini RFS1.8 wheels and the place he's ordering from is going to give him a 20-25 in the front and a 40-42 for the rear, unless he tells them otherwise.

    Update: They are now recommending he go with a square wheel setup of 20x10 with a 35 offset and that he can run up to a 285 on the front and a 305 on the back, without rubbing. This sound right?

    Thanks!

    Nice! My son went back and forth between the dual bronze and the dual black. Ultimately he settled on the dual black. They are great looking wheels. Even considering them for my GT500 if they'll make a set that will fit.

    I’d probably go with a good compound 275 or 285 square, with a 35 offset and call it a day. A 305/30 will work but that’s on the wide side for a 10” wheel. With that offset and wheel/tire size, you should have no fitment issues

    If it is any consolation, the PP2 has 305/30R19 all around but they use 19”x10.5”, 24 offset front and 19”x11”, 48 offset rear.


    Check out a tire calculator to see the difference. I tend to use this one:
