Do I need an alignment after fitting the arms?

Yes. Changing the rear toe arms alters toe and bump steer, so a full alignment is required after installation. The turnbuckle body makes that alignment easier than with the fixed factory arms, and the adjustable end shaft lets the shop set the arm angle for your ride height.

Do the Rear Control Arms for AP1 cars also fit the AP2?

Yes. The Rear Control Arms for AP1 cars are listed for every S2000, from the 1999 to 2003 AP1 to the 2004 to 2009 AP2. They are sold as a left and right pair, and the same bump steer adjustment works at stock height or on a lowered car.

How durable are the pillow ball joints?

The manufacturer uses pillow balls made from a corrosion-resistant material and states they give sufficient durability in normal use. If a joint is ever damaged, it can be repaired with separately sold service parts rather than replacing the whole arm.

What problem do they fix on a lowered S2000?

Bump steer. Lowering the car tilts the toe arm out of its intended angle, so the rear toe changes sharply as the suspension moves and the car can feel nervous. The adjustable end shaft lets the arm run close to horizontal, where toe change on this chassis is relatively small.

How do they help with camber?

Because the arm length can be changed, the factory eccentric cam camber adjusters can be used through their full range. The manufacturer says this raises the maximum camber available and widens the track setting, giving more room to tune the rear of the car.

J’s Racing Rear Control Arms for AP1 / AP2 Honda S2000

J’s Racing’s Rear Control Arms for AP1 and AP2 S2000s replace the factory rear toe arms, which use rubber bushings, cannot be adjusted and run out of ability once the car is lowered and driven hard. The Osaka tuner spent six years testing before releasing this pillow-ball design, built from 2017 aluminum with a turnbuckle body that makes alignment work much quicker. To J’s Racing, bump steer and roll center correction are the heart of S2000 suspension setup, and these arms address the first directly. They belong on a lowered car that sees spirited driving or track time; a stock-height cruiser has less to gain.

Design and Performance

On a lowered S2000 the toe arm tilts into an inverted V, and past a certain point the toe change under suspension travel becomes extreme and the rear turns peaky. A collar-adjusted end shaft lets the installer bring the arm back toward horizontal, the zone where the S2000 shows relatively little toe change, at any ride height. Adjustable length also lets the factory eccentric cams deliver their full camber range.

Features

Pillow ball ends restrain the play of the rubber bushings for more linear steering feel
Collar-adjustable end shaft for setting bump steer at stock or lowered ride height
Turnbuckle length adjustment that extends the usable camber and track range
Corrosion-resistant pillow balls, repairable with separately sold parts
2017 aluminum construction that saves weight

About J’s Racing

J’s Racing was established in Osaka in 1989, as VTEC engines and lightweight Civics and Integras were changing what a Honda could do, and it has built parts for Hondas ever since. The company develops engine response, suspension, braking, cooling and aerodynamics together as one system, then proves the parts in time attack, gymkhana, endurance and circuit racing. Its Fit lapped Tsukuba Circuit in 1’00.459, and its naturally aspirated AP1 S2000, the Maou car, became the company’s reference build for the Honda roadster. Every J’s Racing part is designed and tested in Japan, and J’s Racing USA in Carson, California handles distribution in the United States.

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.
