Which cars does the Front Negative Camber Upper Arm Set for RZ34 fit?

Cusco USA lists part number 252 474 K for the Nissan Z (RZ34, 2022-2026), the Nissan 370Z (Z34, 2010-2020) and the Infiniti G37 Coupe (CKV36, 2008-2015). The Front Negative Camber Upper Arm Set for RZ34 bolts on in place of the factory upper arms. Check the model against the Applications list before ordering.

How much camber does it add?

Cusco gives an example of about 0.5 degrees of additional negative camber on a car lowered by 30 mm. The exact figure depends on ride height and the rest of the alignment, so the final reading comes from the alignment rig after fitting.

Is the arm length adjustable?

No. The arms are fixed at 10 mm shorter than the factory setting, so they add a set amount of negative camber. Fine adjustment is still made through the factory alignment points, and an alignment is needed after fitting. For more camber than the fixed setting allows, adjustable camber bolts or top mounts can be added alongside.

Is an alignment needed after fitting?

Yes. Changing the upper arms moves camber and can also change toe, so a full alignment is needed straight after installation. It should be checked again after any change of ride height, because camber changes as the car is raised or lowered.

Does it fit the new Nissan Z as well as the 370Z?

Yes. Cusco USA lists this set for the RZ34 Nissan Z, the Z34 Nissan 370Z and the CKV36 Infiniti G37 Coupe, which share the front suspension layout. Check the Applications list for the exact years before ordering. Fitment depends on the year range Cusco lists for each model.

Description

Cusco Front Negative Camber Upper Arm Set for RZ34 Nissan Z, Z34 Nissan 370Z and CKV36 Infiniti G37 Coupe

Cusco’s Front Negative Camber Upper Arm Set for RZ34 Nissan Z, Z34 Nissan 370Z and CKV36 Infiniti G37 Coupe replaces the factory front upper arms with steel arms set 10 mm shorter than the factory setting to add negative camber. Cusco gives an example of about 0.5 degrees of extra negative camber on a car lowered by 30 mm, with the exact figure varying with ride height. The set suits a lowered Z, 370Z or G37 Coupe that is driven hard, where the factory camber leaves the outside tire on its shoulder in a corner.

Design and Performance

On these cars the front upper arm sets how far the top of the wheel leans in, and the factory range is limited once the car is lowered. The Front Negative Camber Upper Arm Set for RZ34 fixes the arm 10 mm shorter than the factory setting, which pulls the top of each wheel inward. That keeps the tread flatter on the road in a corner, for more front grip and more even tire temperatures on track.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
