What makes the Öhlins Dedicated Track system different from the Road & Track coilover for the E46?

The Öhlins Dedicated Track system is a purpose-built track-only product, while the Road & Track kit is engineered for dual street and track use. The Dedicated system uses Swift-manufactured race springs built to Öhlins' own specifications, higher spring rates (120 N/mm front, 160 N/mm rear), racing camber plates at the front, and spherical bearing rear upper mounts. Each application is shake-rig developed and track validated with specific clicker settings and ride height targets already established for the E46 platform.

Is the Öhlins Dedicated Track coilover for the BMW E46 M3 and 3 Series legal for street use?

No. The Öhlins Dedicated Track coilover system (BMU MU30S1) for the BMW E46 M3 and 3 Series is for off-road and track use only. It is not designed, validated, or approved for use on public roads.

What spring rates does this Öhlins Dedicated Track kit use for the E46?

The front spring rate is 120 N/mm and includes a tender race spring. The rear spring rate is 160 N/mm. Both sets of springs are manufactured by Swift to Öhlins' own specifications and are developed specifically for the E46 platform as part of the Dedicated program's validated setup.

How is damping adjusted on the Öhlins Dedicated Track E46 system?

Damping is adjusted via a single 20-click knob on each corner, which controls both compression and rebound simultaneously. The front uses racing camber plates and the rear uses spherical bearing upper shock mounts. Ride height on both axles is set independently via spring preload adjusters.

Are the Öhlins Dedicated Track dampers for the BMW E46 rebuildable?

Yes. The Öhlins Dedicated Track dampers for the BMW E46 M3 and 3 Series are fully rebuildable, which also allows for custom revalving to accommodate different spring rates or more specific circuit setups. Contact Öhlins or an authorized Öhlins service center for rebuild and revalving support.

The Öhlins Dedicated Track coilover system for the BMW E46 M3 and 3 Series (2000-2006) exists for one reason; to give a serious track driver a complete, race-ready suspension package that installs and works. Where most aftermarket coilovers hand the setup process back to the buyer, the Öhlins Dedicated program takes a different approach. Every application is shake-rig developed and track validated, arriving with specific spring rates, clicker settings, and ride height specifications already dialed in for the E46 platform. Bolt it on, set your ride height, and focus on driving rather than development.

What the Dedicated Program Means

The Öhlins Dedicated program is not a Road & Track kit with stiffer springs. It is a purpose-built system engineered from the ground up for track performance, where Öhlins treats the entire chassis as a single system rather than developing dampers and springs in isolation. The E46 M3 and 3 Series kit uses Swift-manufactured race springs built to Öhlins’ own specifications; not catalog springs selected at the end of the process, but components developed alongside the valving and geometry targets for this specific platform. The result is a coilover that arrives calibrated, not approximate.

DFV Technology and Damping Adjustment

Öhlins’ patented Dual Flow Valve (DFV) technology provides the tuning balance the Dedicated program depends on. The DFV allows engineers to build force curves that deliver strong chassis control over the rough sections of a circuit while keeping the suspension composed over curbing and track imperfections; two demands that typically work against each other in a single-purpose setup. The valve opens a secondary oil bypass at high shaft velocities, preventing the harshness that comes from a purely stiff tune without sacrificing the support the E46 needs when loaded hard.
Damping is adjusted via a single 20-click knob. The front uses racing camber plates; the rear uses spherical bearing upper shock mounts. Both axles include compression and rebound adjustment via one adjuster alongside a spring preload adjuster.

Construction and Specifications

The front struts use strengthened inverted monotube construction with racing camber plates and a 120N/mm spring rate, including a tender race spring. The rear uses aluminum body monotube shocks with spherical bearing upper mounts and a 160N/mm spring rate. The stiffer rear rate is consistent with the track-focused tuning philosophy of the Dedicated program and the rear-weighted handling balance of the E46 platform under hard cornering. Target ride height reduction is approximately 20mm on both axles. All dampers are fully rebuildable.

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.
