Versus the 2017–2019 Dodge Challenger record: the size lineup carried over; wheel specs or trim details shifted.

FIG. 10· what 305/35R20 actually means
wheel · 20″ 305 mm section width 35% of width = 107 mm ∅ 28.4″ overall
Overall diameter28.4″Sidewall107 mmRevs/mile ≈710

305 = tread width in millimetres · 35 = sidewall height as a percentage of that width · R20 = radial construction on a 20-inch wheel. Two sizes with the same overall diameter are speedometer-compatible, that is the whole game in staggering.

Run these sizes in the calculator: this era ships square, so start from 305/35R20 and test any wider-rear pairing in the stagger calculator, keeping the diameters within 1%.

Fitment hardware

Dialing in how a setup sits on this platform? Hub-centric wheel spacers fine-tune effective offset and caliper clearance one axle at a time, aftermarket wheels usually need lug nuts in the matching seat and thread, and aggressive fitments bring adjustable control arms into play for camber. Code KSPAF takes 5% off at KSP Performance. Start with the measurement math in the wheel spacer sizing guide.

Checking an aftermarket stagger for this car? Run the pairing through the stagger calculator. OE fitment data from Wheel-Size.com; years and packages vary by market.
