Why do R35 GT-R owners replace the rear camber arms?

The factory rear camber arms on the R35 GT-R are fixed, which means there is no way to adjust camber at the rear without replacing the arm entirely. Once a car has been lowered or is running modified suspension, the stock geometry rarely sits where it needs to. The Top Secret rear camber arms R35 GT-R solve that by replacing the fixed arm with a fully adjustable unit so camber can be set precisely for the build and driving conditions.

What effect does rear camber adjustment have on the R35's handling?

Rear camber affects tyre contact patch, straight-line stability, and how the car rotates through a corner. Running more negative camber at the rear improves cornering grip and tyre wear consistency on track but can reduce straight-line traction and accelerate inner tyre wear on the street. Adjustable arms let you find the right balance for how the car is actually used rather than defaulting to a fixed factory value that was not designed with modified suspension in mind.

How does the turnbuckle system work and why does it matter?

The turnbuckle allows arm length to be changed by rotating the center section, which alters camber without removing the arm from the car. More importantly, it is designed to be accessible without pulling the undercover, so adjustments at the track can be made quickly between sessions rather than requiring a full undercar strip.

Are pillow ball ends noticeably harsher than the factory rubber on the street?

They are stiffer, and on rough surfaces that difference is felt. Factory rubber bushings absorb some road noise and micro-vibration that pillow balls pass through more directly. For builds that see regular track use alongside street driving the tradeoff is worth it; for a car that is purely street-driven and rarely sees a circuit, it is worth factoring into the decision.

Do these arms work alongside other aftermarket R35 suspension components?

Yes. The Top Secret rear camber arms are designed for the R35 platform and work with other suspension modifications including lowering springs, coilovers, and adjustable tension arms. Running adjustable arms across multiple rear geometry points gives more precise overall alignment control than a single adjustable arm paired with fixed OEM components.

Top Secret Rear Camber Arms for R35 Nissan GT-R

The Top Secret rear camber arms R35 GT-R owners need when the factory geometry stops being adequate are built around the same core problem: the OEM arms are fixed, so camber cannot be changed without a full arm swap. These replace that fixed setup with a fully adjustable pillow ball arm in STKM13 carbon steel, giving a free range of camber adjustment that covers conservative street alignment through aggressive track configurations. The turnbuckle adjustment system works without removing the underbody cover, which matters when you are making changes between sessions at the circuit rather than on a lift. Pillow ball ends replace the factory rubber, removing the compliance that causes rear geometry to shift under load and replacing it with a consistent, direct feel that holds the set alignment rather than deflecting away from it.

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.
