How much rear camber adjustment does this give?

Significantly more than the OEM eccentric — well outside stock range, suitable for track-spec setups.

Do I keep the OEM lower control arm?

Yes. The cartridge presses into the OEM control arm housing — no full arm replacement.

Will I feel more road noise?

Yes, slightly — spherical bearings transmit more feedback than OEM rubber.

Do I need an alignment after install?

Yes. After the cartridge is installed, take the car to a four-wheel alignment to dial in your camber and toe.

What is the lead time?

Made-to-order. Confirm build time at the time of order.

Frequently Asked Questions

How much Porsche 911 rear camber adjustment does this cartridge provide? Significantly more than the OEM eccentric, well outside stock range and suitable for track-spec setups requiring aggressive rear camber values.
Do I need to replace the OEM lower control arm to use this cartridge? No. The Porsche 911 rear camber adjustment cartridge presses directly into the OEM control arm housing; the factory arm is retained.
Will I notice more road noise after installing the spherical cartridge? Yes, slightly. Spherical bearings transmit more road feedback than OEM rubber, which is a normal characteristic of the upgrade.
Do I need an alignment after installing the Porsche 911 rear camber adjustment cartridge? Yes. After installation take the car to a four-wheel alignment to dial in camber and toe values.
What is the lead time on Paradox Performance camber cartridges? These are built to order in Costa Mesa, California. Current build time is confirmed at the time of order; contact us for the latest lead time before purchasing.

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.
