ISR Performance Billet Engine Mount Set for Nissan 350Z and Infiniti G35. These mounts feature a 2-piece billet design, allowing for true isolated mounting when using polyurethane bushings. They can also be used as full solid mounts by easily swapping the inserts for solid aluminum ones (sold separately or as an initial option). These are a significant upgrade over the OEM rubber mounts, providing a stronger mount in a more compact package.

  • 2-piece compact billet mounts
  • Polyurethane or solid aluminum inserts


Legal only for use on competition vehicles that are not registered, licensed, and cannot be used on public roads or highways. May also be used on other exempt vehicles.


    Before You Order

    〇 Regarding Import Consumption Tax
    At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

    Checking Compatibility
    All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
    If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
    Please note that even if products are sorted by selecting the year, make, and model from the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
    All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us if you have any questions before ordering.

    ○ Regarding Shipping
    Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.

    Basically, all products are shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery date. Note that all products are transported by air mail. They are never shipped by sea freight.

    ○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
    All products handled by our company are basically designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength study documents or similar for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

    ○ Regarding Warranty
    Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement items for products with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Also, for products sold through our company, we will handle warranty-related matters "only through our company." Please note that we do not handle matters through other companies or distributors located within Japan.
