Does the SPL RLL E46 differ from the SPL RLL E36 that also lists E46 fitment?

Yes. Both arms serve the E46 and share the same construction design; gun-drilled 6061-T6 aluminum, FK rod ends, 360-degree rotating clamp. The key difference is the installation instructions. The E36 version includes specific fitment and torque notes for the E36 and Z1 Roadster geometry as well. The E46-specific version uses a separate instruction set developed specifically for E46 mounting points, thread specifications, and geometry. If you are installing on an E46, use the E46 version and the E46 instruction file.

Why does the E46 in particular benefit from adjustable rear camber arms?

The E46 uses a multi-link rear suspension with a fixed-position rear camber arm that has a limited adjustment range via an eccentric bolt. That range is sufficient at stock ride height; once the car is lowered by more than 20 to 25mm, the rear camber goes negative beyond what the eccentric can correct, which causes uneven tire wear and reduces rear grip. The SPL RLL E46 provides the extended adjustment range needed to bring camber back to the optimal target for performance or track alignments without requiring a full subframe rebuild or custom fabrication.

Are these suitable for Spec E46 race builds?

Yes. The SPL RLL E46 is used in Spec E46 and other E46-based race series builds. The rotating clamp system is particularly valued in competitive settings where alignment needs to be adjusted quickly and repeatably between sessions without specialized tools. The FK rod ends are durable through sustained track use, and the lightweight construction keeps unsprung mass low; both priorities for a properly built Spec E46.

Is there a torque specification I need to be aware of?

Yes. Some earlier versions of SPL's instruction documentation listed 122 ft-lbs for the inner and outer mounting bolts; this is incorrect. The correct torque is the factory-recommended 81 ft-lbs. Use only the current revision of the installation instructions, available via the Dropbox link on this product page.

Do these arms also remove rear camber change under braking and cornering load?

Yes. The FK spherical rod ends eliminate the bushing deflection that allows the factory camber arm's rubber bushing to compress under lateral and longitudinal load. The factory rubber deflects under hard cornering or braking, changing the rear camber dynamically mid-corner. The spherical bearings articulate freely without deflecting, holding the rear camber at the aligned value under all load conditions; a meaningful improvement in rear suspension consistency at the limit.

SPL Parts Adjustable Rear Camber Links for E46 BMW 3 Series

The SPL Parts RLL E46 solves that by replacing the factory camber arm entirely with a fully adjustable unit built from gun-drilled 6061-T6 aluminum links, clamps, and clevises; light, stiff, and corrosion-resistant. The adjustment range extends significantly beyond what the factory eccentric can reach, allowing proper negative camber targets to be hit at any ride height from mildly lowered to full race stance. The rear suspension gains stability and predictability as a result; the contact patch improves, grip is more consistent under load, and tire wear becomes even across the tread.The adjustment process uses SPL’s 360-degree rotating clamp system, which requires only a single 3/16-inch allen key to lock the setting. There are no jam nuts to fumble with while trying to hold the bearing in position, no second wrench, no frustration at the alignment rack between sessions. Set it, lock it. Three-piece FK rod ends manufactured in Connecticut use a Teflon liner chemically bonded to the inner race for quiet, self-lubricating articulation with zero bushing deflection under load; operating from -65°F to 325°F without maintenance or re-greasing.

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.
