Evidence summary

• Documented builds: 6
• Observed range in our build database: ET35 to ET38

• Axle context: In our build database: 6 as part of a staggered setup; 6 front-only for this size. Rear-only or front-only counts are not treated as square.

Compared with OEM

OEM baseline used for geometry: 17×6.5 ET44

Width vs OEM: +2 in

Outer edge 31.4 mm farther toward fender (more outward poke)

Inner edge 19.4 mm closer to suspension (less inner clearance)

Geometry uses the most frequently documented offset when available. It does not mean the wheel “fits” or “will clear.”

Documented offsets

• ET38 — 3 builds
• ET35 — 1 build (evidence only — no dedicated page)
• Unknown — 2 builds

Evidence pages for documented offsets

• ET383 builds

Counts include only builds where offset is actually recorded. Missing offsets are not treated as ET0. Linked offsets meet the size+offset evidence threshold.
