Petri Hub Adapters for Volkswagen & Audi
Some parts are harder to find than the wheel itself.
This is one of them.
by Mads – April 6, 2026
Petri hubs for Volkswagen and Audi are as rare and collectible as the wheels they support. Short, long, and solid variants exist for different models, each with unique fitment and horn contact setups. Understanding these differences is key for anyone restoring or retrofitting a classic VW Passat TS, Scirocco TS, or Audi Fox GT.
Why a Hub matters
Petri steering wheels are fantastic, but mounting them is a challenge.
Each car model requires a specific hub to connect the wheel to the steering column. VW and Audi were no exception:
- VW Passat TS
- VW Scirocco TS
- Audi Fox GT
The hubs differ in length, internal structure, and horn contact setup, making them just as rare as the wheels themselves.
Hub Variants for Volkswagen & Audi
1. Short Hub (400mm deep-dished wheel)
- Used exclusively with the 400mm deep-dished Petri
- Reason: depth of the wheel reduces hub length
- Part numbers: 841 419 655, 321 419 091 A
- Structure: collapsible interior, hard hub cover
- Purpose: ensures correct horn and wheel alignment
2. Long Hub (380mm flat wheel)
- Standard hub for flat 380mm Petri wheels
- Collapsible internal structure similar to Momo hubs
- Top design differs slightly depending on Scirocco vs Passat
- Hub cover: hard plastic, non-collapsible
3. Solid Hub (VW / Audi Fox variant)
- Similar in appearance to BMW hubs
- Solid design, no collapsible net structure
- Petri logo only, narrower cover compared to the other long hubs
- Fits VW Passat TS, Scirocco TS, and Audi Fox GT steering columns
Interesting Facts
- Multiple hubs for the same car model? Petri made small adjustments for wheel depth, horn contact, and possibly aftermarket options.
- Horn button compatibility: each hub type affects which horn button can be mounted correctly.
