This is a replacement rim for people who already own a PXN V99 force feedback base and find the stock round wheel underwhelming. Below: install steps, exactly what it fits, and the pitfalls worth knowing before you buy.
Overview
The Obokidlyamor F1 Formula rim is a replacement steering rim built specifically for the PXN V99 force feedback base. Swapping the stock round rim for a flat-top, flat-bottom Formula shape opens up your view of the dash and the road ahead, and puts your hands in a more authentic open-wheel position.
It weighs 1.2 kg, connects over USB through the base, and is recognized as a gamepad on PC.
Think of it as a way to raise the experience without replacing the base. Moving to a direct drive wheelbase is a far larger investment; a rim swap keeps your existing hardware.
The flip side is that force feedback strength and fidelity do not change at all. Misreading that is the fastest route to disappointment.
Amazon.co.jp shows 9 reviews averaging 4.0 out of 5 (80%, captured 19 May 2026).
With only 9 reviews, that average is not statistically stable — a single new one-star review moves it by roughly 0.3.
Treat it as a weak signal.
Compatibility Guide
The compatibility story is blunt: it fits the PXN V99 and nothing else. The selling point is pre-drilled holes matched to the V99 screw pattern, which by definition means other bases will not line up.
| Item | Detail |
|---|---|
| Supported base | PXN V99 only |
| Not supported | Logitech (G29/G920/G923), Thrustmaster, Fanatec, MOZA, and other brands |
| Platform | PC (USB, recognized as a gamepad) |
| Weight | 1.2 kg |
| In the box | Rim, hex driver |
Installation is non-destructive. Using the included hex driver, remove the six large front screws and the four small rear screws, lift off the stock rim, fit the new one, and retighten only the six front screws.
The four small rear screws are not reused. Nothing on the base or its wiring is modified, so you can always revert to the stock rim — a real safety net if you are unsure.
Note that this is not a universal quick-release adapter. Universal QR systems use industry-standard 70 mm or 50.8 mm bolt patterns; this rim is drilled for the V99 directly.
If you later move to a MOZA or Fanatec base, assume this rim will not come with you.
Published specs say nothing about buttons, paddles, or rotary encoders, or whether the stock rim's wiring transfers over. Check the listing photos and description before ordering — that detail shapes day-to-day usability more than anything else here.
Product Info
As captured on 19 May 2026, the Amazon.co.jp price was ¥26,240 including tax.
Prices move a lot with sales and marketplace seller changes, so check the listing for the current figure. The eBay entry is only a search link with no confirmed price.
Published specifications cover weight (1.2 kg), USB connection, PC support, gamepad controller type, PXN V99 compatibility, and the included rim plus hex driver.
Material (aluminum, plastic, carbon-look trim), grip surface, and warranty period are not stated. On a sim racing rim, material largely determines rigidity and feel, so treat that gap as a genuine minus.
The seller and shipper are listed as ジェネロシティー, and the manufacturer as Obokidlyamor. Brand naming is consistent across the title, specs, and listing data — no obvious mismatch.

Installation Tips
The job takes roughly 10–20 minutes and needs no special tools, but a few habits prevent mistakes.
Power down the base and unplug USB first. Turning the rim while powered can throw off calibration.
Center the wheel before removing screws. Re-centering afterward is much easier.
Sort the screws by type. The six front and four rear screws differ in length.
Keep the stock rim boxed if you might revert. 4.
Tighten diagonally, a little at a time. Over-torquing one screw seats the rim crooked and shows up as play while driving.
- Recalibrate and verify center in-game. A different rim shape changes how center looks to your eyes.
The bundled hex driver is small and awkward to torque. An L-shaped hex key set makes the job noticeably easier.
What Actually Changes — and What Doesn't
Three things change. Visibility improves, since the flat top clears your view of the dash.
Hand placement becomes natural for a fixed 9-and-3 grip, which suits titles where you never shuffle your hands. And the look and feel of the rig improves, which matters more than enthusiasts admit.
What does not change is force feedback output, precision, or response — those belong to the base. Rim diameter can alter perceived torque (smaller feels heavier), but the exact diameter is not in the published specs, so no claim can be made here.
Check the listing.
Also, a Formula rim is a poor fit for titles needing more than 360 degrees of rotation. For rally, drift, GT, or street driving, a round rim is simply faster and easier.
That is a use-case question, not a taste one.
Best Use Cases
- PXN V99 owners who mainly race open-wheel titles such as the F1 series, where low rotation and a fixed grip make the Formula shape a direct usability win.
- Anyone wanting a step up before committing to a new base. The outlay is far smaller than direct drive, and the swap is fully reversible.
- Racers who value immersion and the look of the rig. In sim racing, presence is a large share of satisfaction.
- People comfortable with basic disassembly. One hex driver is all it takes, but if opening hardware makes you nervous, skip it.
Things to Check Before Buying
The biggest issue is expectation versus price. At ¥26,240 as captured on 19 May 2026, this is not cheap for an accessory that improves no force feedback metric.
The same budget spent on better pedals or a rigid wheel stand/cockpit may do more for both lap times and comfort. In particular, if your base is still clamped to a desk, fix the mounting before you touch the rim — nothing feels consistent on a moving surface.
There is zero cross-brand portability. It fits nothing but the PXN V99 and cannot be carried to a future base.
If a base upgrade is on your near-term horizon, put the money there instead.
Material, warranty, rim diameter, and button wiring are all absent from published info. Unclear warranty terms mean initial-defect handling depends entirely on the seller, so read the listing's return policy first.
Also worth knowing: Amazon listing metadata — manufacturer, model number, category — occasionally carries details from a different product. Nothing here looks contradictory, but confirm from the photos and title that you are buying the rim alone for the PXN V99. No base and no pedals are included; ordering without understanding that guarantees a bad surprise.
And again, 9 reviews is a thin sample. A 4.0 average is fine, but it cannot tell you anything about long-term durability or how often play develops.
Treat this as a lightly-documented option, not a proven staple.
FAQ
Q. Will it fit a Logitech G29, Thrustmaster, Fanatec, or MOZA base? A.
No. The holes are drilled for the PXN V99 and will not align with other brands.
Q. Does installation require modifying the base? A.
No. Remove six front and four rear screws with the included hex driver, fit the new rim, and retighten the six front screws.
It is fully reversible.
Q. Will force feedback get weaker? A.
Base output is unchanged. Rim weight and diameter can alter how the force feels; this rim weighs 1.2 kg.
Q. Does it work on PS5 or Xbox? A.
The listed supported device is PC only. Console behavior depends on the base, so check your base's support first.
Q. Do buttons and paddles carry over? A.
The published specs do not state whether buttons or paddles are present or how wiring transfers. Verify from the listing photos and description.
Q. Is it good for rally or drifting? A.
Not really. Genres with large steering inputs favor a round rim; Formula rims suit low-rotation open-wheel racing.
