Fast answer: Choose a widebody kit only after the exact vehicle, original system, retained functions and installation path are documented.
Page scope: Primary guide for full widebody planning; daily-use and wheel-plan questions stay narrow.
Options Comparison
| Option | Use it when | Verify before purchase |
|---|---|---|
| bolt-on overfender kit | Factory integration or the simplest defined route is the priority | Application, included parts, retained functions and installation requirements |
| molded widebody | A broader upgrade is justified by confirmed evidence | Application, included parts, retained functions and installation requirements |
| full replacement-panel conversion | A specialist-led project accepts additional complexity | Application, included parts, retained functions and installation requirements |

Common Questions
Should wheels be chosen before the kit?
The wheel and body plans should be engineered together.
What is the minimum acceptance test?
Test every original and added function, inspect physical fit and finish, scan for faults where applicable, and record the final configuration.
Is a matching product photo enough evidence?
No. Use vehicle, part-number, connector, function and installation evidence.
