The Sikky 350Z Quick Change Rear Kit is a critical addition when building a top-tier performance race car. This setup allows the user to change gear ratios within 5 minutes by simply removing the rear cover of the rear end. This is a huge advantage when adjusting your setup at the track to ensure your gearing is in the sweet spot and you aren't forced to shift at the wrong time. It is also designed to handle massive amounts of power. Our customers use this setup in cars well over 1,200 horsepower.
We designed, developed, and tested our subframe kit to withstand the most grueling conditions. Using advanced technologies like the FARO 3D scanning arm and Solidworks CAD software, we design and build every subframe assembly to precise tolerances. Perfect rear placement ensures that the differential is always centered for optimal CV joint angles while remaining Formula Drift legal. Designed to handle all the abuse high-horsepower cars can dish out. The subframe ships fully assembled with the necessary brackets welded and the entire assembly powder-coated black. There are options to add a Sikky Winters IRS Rear, Sikky Solid Subframe Bushings, driveshafts, and/or heavy-duty axles. If you want a competitive edge over the field, the Sikky Winters IRS Subframe Kit is your best choice.

Before Ordering
○ Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred during import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
○ Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm whether or not parts can be installed on Japanese domestic vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure if a listed product is compatible with your vehicle. Our support team will be happy to investigate for you.)
If you 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 using the tabs on our top page, it does not necessarily guarantee that 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 before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, 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 confirm delivery times. All products are transported via air freight. They are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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 packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or exchanges for products with shipping damage, defective items, or items different from what was ordered if you contact us within 7 days of receipt. Furthermore, regarding products sold through us, please note that we will only handle warranty-related matters "directly through us." We do not handle matters through other companies or distributors located within Japan.
