Frequently Asked Questions (FAQ)

1. Ordering & Payments

What payment methods do you accept?

We accept Visa, MasterCard and American Express, as well as Apple Pay, Google Pay and Shop Pay. For larger or wholesale orders, we can also invoice you for payment by bank transfer (Wise) — contact us for a quotation.

What currency do you charge in?

All prices are in US dollars (USD). Your card issuer will convert the amount to your local currency at its own exchange rate.

Can I cancel or change my order?

Please contact us as soon as possible with your order number. Once an item has shipped, or once a special-order or made-to-order item has been ordered from the manufacturer, it can no longer be cancelled or changed.

2. Lead Times & Availability

When will my order ship?

Lead times vary by product and are shown on each product page under the price:

• In stock: Usually ships within 3 business days.
• Ordered for you: Ordered from the manufacturer after your purchase. Usually ships within 7 business days.
• Made to order: Produced after your purchase. Usually ships within about 1 month.
• Long lead time: Some items, such as forged wheels, currently take 6 months or more.

If a lead time is not shown, please contact us before ordering and we will confirm it with the manufacturer.

How do I order RAYS or WORK wheels?

Most wheels are built to order and production can take several months. Some sizes may be in stock. Please contact us to confirm the lead time before ordering. Reservation orders with a deposit are available, and we will confirm your fitment (size, offset, bolt pattern, center bore) before placing the order with the manufacturer.

3. Shipping & Delivery

Do you ship internationally?

Yes. We ship worldwide from Japan, mainly by FedEx. Some products are stocked at our office in California, USA and ship domestically within the US — these are marked "Ships from California". Oversized items such as wheels and body parts may have destination restrictions; contact us if you are unsure.

How long does delivery take?

• Within the USA (ships from California): Usually 5–7 business days.
• Japan to USA / Canada / Europe / Australia: Typically 5–10 business days by FedEx after shipping, plus customs clearance.
• Other destinations: Varies by region and customs. Contact us for an estimate.

These times are after the item ships — please add the lead time shown on the product page.

How much is shipping?

Shipping is calculated at checkout based on the destination and the weight and size of your order. Free shipping is available on selected items from both Japan and the USA. For wheels, large parts or multi-item orders, contact us for a quotation — combined shipping is often cheaper than the checkout rate.

Are import duties and taxes included?

No. Orders shipped from Japan are sent on DAP terms: import duties, VAT/GST and any customs or carrier handling fees are not included in the price or shipping charge and are billed to you by customs or the carrier (FedEx) when the item arrives. The amount depends on your country's rules — please check with your customs authority before ordering. Orders shipped from California to US addresses have no import duties.

We cannot declare a lower value or mark a commercial order as a gift.

How do I track my order?

You will receive a shipping confirmation email with a FedEx tracking number as soon as your order ships. Please check your spam folder if you have not received it.

4. Returns & Refunds

Do you accept returns?

Unused, unopened items in their original packaging may be returned within 14 days of delivery. Please contact us for approval before sending anything back. Return shipping, the original shipping cost and any import duties are the customer's responsibility.

The following cannot be returned unless defective:

• Special-order and made-to-order items (including all wheels)
• Items that have been installed, used or modified
• Fluids, chemicals and coolants with broken seals

What if my item is defective, damaged or incorrect?

Email info@kurumaya-tokyo.co.jp within 7 days of delivery with your order number and photos of the item and packaging. If the problem is due to our error or shipping damage, we will arrange a replacement or refund at no cost to you. Please keep all packaging until the claim is resolved — FedEx may need to inspect it.

What happens if I refuse delivery or do not pay the import duties?

Shipments refused or abandoned at customs are returned or destroyed at the customer's expense. Any refund will be issued only after the item arrives back with us, minus the original and return shipping costs and any carrier charges.

5. Products & Fitment

Are your parts genuine?

Yes. All products are genuine items sourced directly from the manufacturer or an authorized Japanese or international distributor.

Will this part fit my car?

Fitment information is listed on each product page where available. If you are unsure, email us with your vehicle's make, model, year, chassis code and engine before ordering — we are happy to check. Parts purchased without confirming fitment cannot be returned on the grounds of not fitting.

Are your coolants compatible with my vehicle?

Kemitec PG55 Series coolants are suitable for a wide range of vehicles, from race cars to daily drivers and classics. Please refer to each product page for the recommended grade and mixing instructions.

Do you provide installation support?

Installation instructions are provided on the product page where available from the manufacturer. We recommend professional installation. For technical questions, contact us and we will check with the manufacturer.

6. Dry Carbon Fiber Care

Why does dry carbon develop white cracks or fading?

Dry carbon is sensitive to UV light. Without a protective coating, the surface resin degrades over time, causing white cracking and fading.

Is a coating required?

Yes. We strongly recommend applying a UV-cut clear coat or ceramic coating before use and avoiding extended exposure to direct sunlight. Damage caused by UV exposure on uncoated parts is not covered as a defect.

For details, see our guide: Dry Carbon Fiber Care & Protection.
