Wheel Offset & Fitment Calculator
Thinking about wider or more aggressive wheels? Enter your current and new width + offset to see exactly how far the wheel moves out (poke) and how much inner clearance you gain or lose.
Current wheel
New wheel
Outer face
+25.7 mm
more poke (outward)
Inner clearance
-0.3 mm
more room
Positive outer = the wheel pokes further out (more aggressive). Watch inner clearance for coilovers/brakes. Estimate — confirm with a fitment guide.
How offset works
Offset (ET) is the distance in mm from the wheel's mounting face to its centreline. Lower ET pushes the wheel outward (more poke); higher ET tucks it in. Combined with width, it decides fitment, clearance and stance.
