What's the ideal wheel offset for a 17x7.5 rim on a GC with standard 4-pot caliper?

Hi, i would not go any higher than +48 (depend on the wheel's spoke and style) i used to run Gram Lights 18 x 7.5 +43 offset, they sit perfect on the guards and clear Brembo (but rear guards need rolled ) as i'm running 225/40/18 tyres

hope this help

Moving away more then 3-5mm from original offset means a compromise in steering feel and ride quality.  Choosing wheels that fill the arch or clear the brakes normally means more leverage (and force) exerted on the suspension.  Choppy ride and steering kicks are common  symptoms when using these wheels.  So it depends on you as an owner what you want to optimize, the brake clearance, or the dynamic of the car.
