Fitment Adjustment Case
Resolved Fitment Case.
RVRN engineering review and corrective solution for a custom forged wheel fitment issue. When front brake clearance required additional review, RVRN remade the affected front barrels and confirmed final fitment after the second installation.
Final Build
Fitment completed and installation confirmed.

02 · Build Background
Factory brakes. Max lip goal. Flush fitment.
The customer’s vehicle retained the factory brake setup with no known modifications. The goal was to achieve the largest possible lip depth while keeping the fitment flush and inside the fender line.

03 · Original Fitment Data
The original setup was based on verified data.
RVRN engineering reviewed previously verified installation data, including width and offset references from successful applications. Two fitment options were provided, and the customer approved the final direction before production.
Verified data. Customer-approved direction.
Order placed on 11/17/2025. Engineering drawings confirmed on 12/02/2025.
Two fitment options were presented.
The customer selected one of two fitment options based on the preferred balance of lip depth, stance, and clearance.
Drawings were confirmed before production.
The build moved forward based on the approved setup.

04 · Installation Issue
Rear fitment confirmed. Front caliper clearance required review.
After delivery, the rear wheels installed correctly with no fitment issue. During front installation, the customer reported caliper contact on the front axle.
The front setup needed more clearance margin.
This was not a manufacturing or calculation error. The case showed that previously verified platform data may still require additional clearance margin when maximum lip depth, flush fitment goals, and individual vehicle conditions are combined.

Installation Check
05 · Corrective Solution
Recalculated. Remade. Covered by RVRN.
RVRN recalculated the front width, offset, and caliper clearance margin. To avoid spacer-based shortcuts, two front barrels were remade instead of forcing the original setup to work.
1-hour internal assessment
The customer’s installation photos and videos were reviewed immediately by RVRN engineering.
Revised front specification
Front width, offset direction, and caliper clearance were adjusted to create a safer fitment margin.
Priority Production
Two replacement front barrels were moved into Priority Production after customer approval.
Covered by RVRN
Corrective engineering and production costs were handled by RVRN at no additional cost to the customer.
06 · Final Fitment Confirmed
Final fitment confirmed on 04/30/2026.
The customer completed the second installation and confirmed final fitment.
Completed Installation
Second installation completed.
The revised front setup achieved the required brake clearance, safety margin, and visual fitment goal.

Preventive & Quality Improvements
Max-Fitment Risk Flag
Orders marked for maximum lip depth or aggressive fitment now trigger an additional engineering review before production.
Platform-Specific Safety Margin
The CLS 53 platform record was updated with a revised front clearance window and safer fitment margin.
Vehicle Condition Confirmation
Before production, customers are asked to confirm key vehicle conditions that may affect clearance, including brake setup, suspension changes, spacers, widebody components, fender changes, or previous structural repairs.
Database Risk Marking
This case has been added to RVRN’s fitment database with a special risk note for similar max-lip configurations.
