Installation
Fitting your nuts / bolts
Tightening torque
Recommended, for 60° taper
- 1
Check the hub
Wheel studs (or bolt holes) and the hub face must be clean and free of rust, dirt or damage. Check the nut or bolt thread matches your car.
- 2
Start by hand
Thread every nut or bolt in by hand, then snug them lightly in the order shown below.
- 3
Torque wrench only
WORK recommends 90–120 N·m for M12 / 160–180 N·m for M14 — tighten in a star pattern, never with an impact wrench.
- 4
Re-torque at 100 km
Re-check every nut or bolt with the torque wrench after about 100 km, and after every tyre rotation.
Tightening order
Snug the nuts or bolts lightly in this order, then torque them in the same order.
- Keep a spare set of wheel nuts or bolts in the car.
- Only use nuts or bolts with a 60° taper seat — the type WORK wheels are made for.
- Keep the lock-nut key in the car — you need it to remove the wheel.

Are the wheels genuine?
Yes — every wheel is 100% genuine WORK, shipped direct from WORK Wheels Japan to our Sydney warehouse. Never a replica. We’ve been the official Australian distributor since 2006, and you can verify us on the WORK Wheels Japan website. We’re JDM Concept Pty Ltd, ACN 43 120 929 713, trading from the same Sydney warehouse and the same domain since 2006.
How do I know they’ll fit my car?
Ask us before you buy. Send your car and the model you’re after, and we’ll tell you what clears your brakes, based on real cars we’ve fitted. Guard clearance and tyre setup we leave to your mechanic: confirm those, then send us the spec and we’ll quote it.
How do I order — and how do I pay?
Accessories
In stock: tap Buy and pay by bank transfer (Westpac), or Zip only when every item in the order is in stock. Order from Japan: tap Buy and pay by bank transfer; we confirm the ETA. Every order gets a tax invoice.
Wheels
In stock: tap Buy and pay by bank transfer (Westpac) — or Zip only when every item in the order is in stock. Built to order in Japan: send us your car and spec, we reply within 1 business day with a quote and ETA, then a deposit — 35% in most cases — locks the build in, or pay in full. Every order gets a tax invoice. We don’t take card or PayPal — it keeps pricing sharp.
Can I order custom sizes, offsets and PCDs?
Yes — made to order to your diameter, width, offset, PCD and finish. Most models support 4x100, 4x114.3, 5x100, 5x112, 5x114.3 and 5x120. Singles and pairs available too.
