02 · Build Background
Staggered chrome setup. Maximum rear lip.
The 2014 T-Rex Campagna required a highly specialized staggered 18x8 front and 22x11 rear configuration. The goal was to maximize the rear chrome lip depth while keeping a perfect flush fitment inside the open-wheel fenders.

03 · Original Fitment Data
The original setup was based on verified records.
RVRN engineering referenced widely published OEM technical specifications and past platform records, showing a standard 72.6mm rear hub diameter for production.
Verified specifications. Approved blueprints
Order placed on 09/18/2025. Engineering drawings confirmed on 10/08/2025.
Maximum chrome lip configuration selected.
The client opted for a maximum chrome lip configuration, requiring aggressive offsets on the staggered setup.
Staggered width and load ratings confirmed.
Drawings confirmed the staggered width and load ratings were optimized for the T-Rex's lightweight chassis.
04 · Installation Issue
Rear axle seating mismatch vs Database specs.
While the front wheels seated perfectly, the rear wheel center bore was found to be slightly too tight to slide over the vehicle's rear hub face.
Hub-Centric Tolerances on Classic Platforms.
This minor variance was caused by real-world vehicle conditions. For classic or low-volume specialty platforms (older than 10 years), standard OEM specifications can deviate due to manufacturing tolerances, oxide layer buildup, or previous hub refurbishment.
05 · Corrective Solution
Onsite precision re-machining. Fully reimbursed.
To avoid long shipping delays for the customer, RVRN calculated the required clearance and authorized a local CNC specialist to perform a precision hub bore adjustment.
Immediate Assessment
Engineering team reviewed the case within 1 hour, verifying that the wheel's structural integrity allowed a safe micro-adjustment.
Local CNC Adjustment
RVRN authorized a local professional shop to adjust the rear center bore to match the actual measured hub size.
100% Cost Coverage
All machining and local shop fees were fully reimbursed by RVRN, resolving the issue in just 3 days.
Secure Seating Confirmed
The precision adjustment preserved the hub-centric seating relationship while avoiding unnecessary shipping delays.
06 · Final Fitment Confirmed
Perfect installation confirmed on 12/18/2025.
The customer completed the installation and confirmed flawless seating and high-speed stability.
Bespoke seating completed.
The adjusted rear hub setup achieved perfect, zero-vibration concentricity, delivering the desired aggressive stance and maximum chrome lip effect.

Preventive & Quality Improvements
Specialty Platform Hub Pre-Verification
For classic, low-volume, or custom chassis (older than 10 years): - On-site physical hub measurement is now requested before final production release to verify potential database deviations.
Restoration & Oxide Tolerance Check
Engineering teams must account for historical wear, refurbishments, and protective coating buildup on older hubs, adding a safety clearance margin (+0.1mm to +0.15mm) when necessary.
Multi-Database Cross-Validation
Prior to machining, hub specifications are cross-validated against both official OEM records and our proprietary "real-world build history" database.
Risk Cataloging
