Which cars does the Pillowball Negative Camber Upper Arm for EF8 fit?

Cusco USA lists part number 307 479 A for the Honda CR-X (EF8, EF7, 1987-1991) and the Honda Civic (EF3, EF9, 1987-1991). The Pillowball Negative Camber Upper Arm for EF8 bolts on in place of the factory upper arm. Check the model against the Applications list before ordering.

How much camber does it add?

Cusco makes the arm 15 mm shorter than the factory part and gives it a camber range of 0 to 2 degrees, so camber can be set anywhere in that window on an alignment rig. The exact figure also depends on ride height, because a lowered car gains some camber on its own.

Why add negative camber?

When the car leans in a corner, the outside tire rolls toward its outer edge. Negative camber tilts the top of the wheel inward so the tread stays flatter on the road when the car is cornering hard. The result is more grip and more even tire temperatures on track.

Is an alignment needed after fitting?

Yes. Any change of suspension arm moves the wheel alignment, and adjustable parts are only useful once they have been set on an alignment rig. Have a four-wheel alignment done straight after installation, and again after any change of ride height or arm length.

Is it suitable for daily driving?

Yes, for most enthusiasts. Pillowball joints pass more noise and vibration into the car than rubber bushings, and they should be checked for play at each service, especially on cars driven through winter road salt. Owners who want the quietest ride may prefer to stay within the factory adjustment range.

Description

Cusco Pillowball Negative Camber Upper Arm for EF8 / EF7 Honda CR-X and EF3 / EF9 Honda Civic

Cusco’s Pillowball Negative Camber Upper Arm for EF8 / EF7 Honda CR-X and EF3 / EF9 Honda Civic replaces the factory upper control arm with a shorter arm that runs pillowball ends in place of rubber bushings. Cusco makes it 15 mm shorter than the factory arm, which pulls the top of the wheel inward and adds negative camber, adjustable from 0 to 2 degrees. It suits a lowered EF Civic or CR-X driven on track or canyon roads, where extra negative camber keeps more of the tire on the road in a corner.

Design and Performance

On a double-wishbone car, the length of the upper arm sets how far the top of the wheel leans in. Lowering an EF chassis and driving it hard on wide tires rolls the outside tire onto its shoulder, which wears the edge and costs grip. The Pillowball Negative Camber Upper Arm for EF8 shortens the arm to add negative camber and uses pillowball ends so that angle holds under load instead of moving with bushing flex.

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.
