BMW E36/E46 Rear Grip Kit

BMW E36/E46 Rear Grip Kit:

This kit is designed for the demands of competitive drifting, offering a robust, lightweight design. It is the only kit that provides toe gain under compression, with the ability to be set up for zero bump steer. All other options toe out under compression, which is not ideal for rear grip and control in drifting or racing. The modifications made to the knuckles have been simulated and tested to optimize the already excellent trailing arm suspension for the E36/46 chassis.

• Proven Track Record: Field-tested by pro driver Connor O'Sullivan, who secured 2nd place overall in the 2024 Formula Drift season. This kit demonstrated its superiority in a competitive environment and contributed significantly to a nearly invincible vehicle on the track.
• Superior Design and Materials: Made from high-strength alloy steel, our knuckles are lighter and stronger than OEM knuckles. This kit includes a dual-caliper bracket specifically designed for Wilwood calipers and features a control arm system that is easy to adjust.
• Advanced Engineering: Developed with CAD simulation and FEA testing to meet rigorous racing standards, this kit features adjustable toe gain control, roll center correction, anti-squat adjustment, and pickup hole options to change the amount of side-bite and forward-bite created by the kit.
• Customizable Adjustment: Features adjustable anti-squat settings (FD-legal as standard) and precise toe adjustment using shims for symmetrical alignment. This allows for the fastest and most accurate setup adjustments available on the market for this chassis.
• Durability and Reliability: Equipped with easily replaceable uniball bearings and high-strength heim joints, it is designed to withstand the rigors of racing and maintain performance even after collisions or contact, with all parts available for individual purchase as needed.
• Easy Installation: The included guide and video tutorials streamline the installation process. The weld-on brackets are also simplified, with alignment holes provided for precise placement.
• FD Legal Design: Fully compliant with Formula Drift rules, ensuring the vehicle meets competition standards without compromising performance.
• Easy Maintenance: All components are designed for easy replacement, allowing individual parts to be swapped out quickly in the event of damage.
• Race-Only Application: Specifically designed for racetrack use, with a focus on maximizing competitiveness in every aspect of the kit.

Because this kit is designed for competition, it only works with Wilwood brakes and uses a bolt-on style hub and bearing, which is a superior design to the press-on OEM bearings. Below are the part numbers required to run this kit, corresponding to the options chosen. You must purchase these parts yourself.

Before Ordering

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

〇 Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether the product can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not guarantee 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 checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automatic calculation. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US 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 rush, please inquire about delivery times in advance. All products are transported via air freight; they are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we cannot provide strength calculation documents or similar paperwork for these standards. 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 is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements if you contact us within 7 days of receipt regarding damaged, defective, or incorrect items. Please note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
