HYBRID | M14X1.25 TO M12X1.5 PCD STUD CONVERSION KIT
WARNING If you are using this hardware as a PCD conversion and NOT a standard stud conversion, please ensure the following:
✔ Your selected wheels have 16mm lug holes. If not, lug hole enlargement is required.
✔ Your selected wheels match the factory hub bore. If not, hub centric rings are required.
wütend Race Tech is proud to introduce something revolutionary to the aftermarket automotive industry. Whether you are a general enthusiast looking to perfect the visuals of your passion projects, or a function based competitive driver shooting towards a reduction in lap times, THE solution has arrived. Expanding your wheel options couldn't be easier! If your vehicle comes standard with M14 wheel bolts (14X1.25) you can now..
✔ fit 5x112 wheels on your 5x110 vehicle.
✔ fit 5x110 wheels on your 5x112 vehicle.
✔ fit 5x114.3 wheels on your 5x112 vehicle.
✔ fit 5x112 wheels on your 5x114.3 vehicle.
wütend Race Tech's PCD Stud Conversion can also be utilized as a Standard Stud Conversion!
To understand how our system works we first have to answer the question of what PCD is and why would it need to be converted.
- PCD or Pitch Circle Diameter is the distance between the mounting holes on a vehicle's wheel or hub, in a circle. For example 5 x 112. (5) refers to the number of individual lug holes, or studs. (112) is the distance, in millimeters, apart from each other in a circle in which the studs or lug holes are spaced. A PCD conversion is necessary when the lug holes on a given set of wheels do not match the vehicle hub's PCD.
- Our conversion works by simply offsetting the variance, allowing our PCD variable washer to seat itself center on the lug hole, while the nut shifts its center point to the stud.
Our true PCD Conversion Kit mitigates 99% of the issues one would experience when utilizing other inferior products currently available on the market that are simply band-aids disguised as solutions.
This isn’t a workaround. It’s a purpose-built advancement designed to simplify fitment, preserve performance, and give enthusiasts real flexibility — in both directions — with total confidence.
Why choose wütend Race Tech vs other "solutions"?
OPTION 1: PCD "WOBBLE" BOLTS
| Pros | Cons |
|---|---|
| Sort of works? | Poor material / finish choices |
| Limited lengths available | |
| Head of bolts too large for lug holes / sockets | |
| Poor tolerance / manufacturing |
PCD bolts are designed to make the fitment possible, but they create several issues:
Bulky design – These bolts are much larger than standard hardware. This isn’t just an appearance issue. Most 5x114.3 wheels are designed for smaller 12mm studs, which means the lug holes are made to accept smaller lug nuts. In many cases:
The oversized head of a PCD bolt may not physically fit into the wheel’s lug pocket.
Even if it does fit, there often isn’t enough clearance to get a socket over the bolt head to properly tighten it.
Limited finish options – Typically only available in black or chrome.
Heavier than standard hardware – Adds unnecessary weight compared to factory-style bolts.
Limited length availability – Proper bolt length is critical for safety:
Too short – The bolt may only thread a few turns into the hub, meaning fewer threads are actually securing the wheel.
Too long –The bolt can extend too far through the hub and potentially damage components such as the wheel carrier, wheel speed sensor, sensor ring, backing plate, or brake caliper bracket.
Length compromise – Because many available PCD bolts are too long, you’ll often need to add a spacer to achieve proper thread engagement. Adding a spacer changes your wheel’s effective offset, which can complicate your original wheel fitment choice and limit your wheel options.
OPTION 2: STEP-DOWN STUD CONVERSION
| Pros | Cons |
|---|---|
| Sort of works? | No variable washer to properly center |
| Studs are stressed and forced to compensate variation | |
| Risk of failure | |
| Poor tolerance / manufacturing QC |
Another alternative is replacing the factory wheel bolts with smaller-diameter studs and fixed lug nuts. This method also presents safety concerns:
Risk of failure – There is no floating or variable washer to properly center and distribute load on the wheel seat. As the lug nuts are tightened, the force can stretch and pull the smaller studs outward. Over time, this added stress can weaken the studs and increase the risk of failure.
If one stud fails, additional stress is placed on the remaining studs — which can eventually lead to the wheel no longer being securely fastened.
OPTION 3: SPACER PCD CONVERSION KITS
| Pros | Cons |
|---|---|
| Works but... | Added offset |
| Added rotational weight | |
| Stacking components | |
| Subpar versatility |
Spacer-style PCD conversion kits are another commonly available solution — but they introduce their own set of fitment and performance concerns.
Mandatory added offset – Most conversion spacers add a minimum of 15mm of offset. This is required in order to mount the new conversion studs into the spacer body.
Changes your wheel fitment – That additional offset pushes your wheels outward, which can significantly alter your original fitment calculations. This often complicates wheel selection and may limit your choices.
Added weight – The system requires fastening the spacer to your hub using wheel bolts, then fastening your wheel to the spacer’s studs. This adds extra hardware and unnecessary rotational weight.
More components = more complexity – Instead of a direct mounting solution, you’re stacking components between the hub and the wheel, increasing mechanical complexity.
Subpar versatility – Reverting back to your factory PCD requires removal of all stacked components vs leaving wütend Race Tech's PCD Stud Conversion in place. (Our PCD Stud conversion can also be utilized as a Standard Stud Conversion.
While spacer conversion kits technically allow the bolt pattern change, they negatively impact fitment precision and overall performance.
