Fitment-first buying guidance, with the limits visible.
FitmentIQ Auto is published by Stefan Junk Holding UG (haftungsbeschränkt). Stefan Junk is the editorial owner and accountable contact.
How recommendations are produced
We define the fitment question and scoring criteria before selecting products. Product facts come from current manufacturer documentation and official fit tools, with retailer pages used for approximate price context.
Unless a page explicitly says otherwise, products have not been hands-on tested. We do not invent ratings, owner quotes, professional review, fit guarantees, or first-person experience.
Sources, jurisdictions, and updates
Manufacturer manuals and fit tools control product fit. Vehicle manuals, regulators, standards bodies, and qualified installers control safety-sensitive or jurisdiction-specific questions. General comparisons and prices are reviewed at least every 90 days.
Changed fit data, recalls, conflicting official instructions, or unclear legal requirements trigger removal or qualification until an authoritative source resolves the issue.
Corrections and expertise boundary
Corrections and source concerns can be sent to [email protected]. Material corrections are applied to the affected page and its review date.
The site provides editorial buying context, not legal, repair, electrical, engineering, installation, or safety-certification advice. No credentialed expert review is claimed unless a page names the reviewer and scope.
