What does the Rear Control Arm Kit for AP1 do?

It lets rear toe be adjusted independently and uses adjustable angle spacers to reduce bump steer. On a lowered S2000 the Rear Control Arm Kit for AP1 helps the rear wheels hold their alignment over bumps and curbs, so the car stays settled when the driver commits to a corner.

Does it fit the AP2 as well?

Yes. Spoon registers every AP1 and AP2 S2000 from 1999 to 2009 for this part number, and Go Tuning sells it for 2000 to 2009 model year US cars. The same kit serves early and late cars, including the US 2004 and 2005 models.

What is bump steer and why does it matter?

Bump steer is a change in toe as the suspension compresses and extends. When an S2000 is lowered the rear arms sit at a different angle, so the rear wheels can steer slightly over bumps. That makes the car feel nervous at speed, which is exactly what this kit is meant to calm.

Is the kit worth it on a stock-height car?

Usually not. Its value is in correcting geometry that lowering has disturbed. A car on factory springs at factory height keeps the toe curve Honda designed. Owners who have lowered the car, or who drive it on track, gain the most from the adjustment.

Does the kit need an alignment afterward?

Yes. The kit changes how rear toe is set, so the car must be aligned once the parts are fitted and the ride height is final. Setting the angle spacers correctly takes experience, so a shop that knows the S2000 is the right place for the work.

Spoon Sports Rear Control Arm Kit for AP1 / AP2 Honda S2000

The Spoon Sports Rear Control Arm Kit for AP1 and AP2 Honda S2000 addresses the part of the car that makes or breaks driver confidence at the limit: the rear. Lowering an S2000 changes the angle of the rear arms, and the toe change through bump grows with it, which shows up as a rear that steers itself over curbs and mid-corner ridges. Spoon builds this kit so rear toe can be set independently, and it adds adjustable angle spacers to reduce rear bump steer. Go Tuning describes the construction as stainless steel, chosen for strength and reliability over aluminum. Spoon developed its S2000 parts on the cars it races and tunes at Type One, and this kit belongs with that work: it suits a lowered car driven hard on track, while a stock-height street car seldom needs 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.
