EM Sport Coilovers

NOTE: General availability of the EM Sport coilovers is not expected until late Fall, 2008. Different avenues for manufacturing are being explored that meet our pricing and capacity goals.

Zzyzx Motorsports: EM Sport Coilovers

Zzyzx Motorsports is proud to announce a newly developed set of coilovers, targeted at a much lower price point than our current all-aluminum Competition coilovers. To date, the market has lacked a proven set of affordable coilovers based on the tried-and-true KONI 8611/8610 series dampers. That time has come: the "EM Sport" coilovers have arrived.

Our expertise in the design and manufacturing of coilovers for the Mitsubishi Evolution and Subaru Impreza (WRX, STI, RS) using KONI dampers has enabled many of our customers to trophy at SCCA National autocross events, where our products have undergone extreme conditions and been proven to provide a winning combination for our die-hard motorsports competitors.

This time, we turned our efforts to producing a set of coilovers for you, the enthusiast. However, the flexibility in our design addresses the needs of not just a street-oriented enthusiast looking for a sporty ride, but ultimately the same level of performance demonstrated by our Competition coilovers. Unlike any other offering currently available, these coilovers can be upgraded and specifically configured to suit your needs by you when you first purchase them and when you later decide to upgrade them.

As your interests and experience evolve from street-oriented performance to a serious Time Attack or autocross dedicated ride, these coilovers can be user upgraded to address your performance goals. What does this mean? You save money by not having to buy an entirely new set of coilovers once you’ve surpassed your current sets limits. You save time not having to re-install your suspension and, most importantly, you save setup time on the track.

Features

• User configurable, user upgradeable. You can start with a set of single adjustable KONI dampers and upgrade as needed to double adjustable. No need to go out and buy an entirely new set of coilovers. Included in the upgrade kits from single adjustable to double adjustable are the built-in dial bump adjusters.

• Strut bodies constructed out of 4130 Chromoly steel, stress relieved and heat treated for superior structural rigidity and toughness. Nobody offers a strut as tough, durable and stiff as these. In addition, the strut bodies are also cadmium plated and then powder coated (or painted) for unsurpassed corrosion resistance.

• Single height adjustable via a threaded billet aluminum lower spring perch with a coarse "round" thread pitch and ball detent mechanism, making ride height adjustments quick, easy, precise and repeatable.

• Ride height adjustment using a "witness mark" machined into the strut body for unambiguous and repeatable measurement of lower spring perch height using a fixed reference point.

• Billet aluminum upper spring perches include a built-in thrust bearing assembly to eliminate spring noise and stiction during steering inputs. There’s nothing more annoying than a noisy set of coilovers and addressing small details such as these are what results in a silent set of coilovers.

• Bolt-on application specific brake and ABS sensor brackets for OEM-style fitment.

• Large dial rebound adjusters (at the top of the damper) and built in dial bump adjusters (if double adjustable, at the bottom of the strut). This ensures you can accurately and quickly change your settings when needed, and not have to run around looking for that tool you lost. The detents – “clicks” - on the bump adjusters are so easily felt by touch, you don’t even have to see under the car to set them – just reach under and count the clicks. And unlike many coilovers, there’s no guessing as to what the min and max settings are – they have positive stops.

• Your choice of spring rates. Thanks to the wide adjustment range of these KONI dampers, they support a wide range of spring rates. Simply put, they'll handle whatever spring rates you require in your application and we know this from first-hand experience in competition. So, if you’re after a smooth ride with softer spring rates, these coilovers will deliver. If you want to go stiff with minimal body roll, got for it. Due to the highly digressive valving, the ride will not be punishing or jarring, as is often the case with most Asian-manufactured coilovers.

• Wide range of camber adjustability using a unique proprietary eccentric bolt design. We've developed an eccentric bolt design that offers an unmatched range of camber adjustment – both front and rear - that is positive locking. Based on feedback from our competition coilovers, we felt it a high priority to have a positive locking camber adjustment mechanism, so we did just that. Depending on your goals, you could easily forego camber plates and simply use the eccentric bolts to set your camber.

• Unparalleled rear strut/tire clearance (Subaru only). Rear flange ears are extended to provide additional strut/tire clearance not offered on other coilovers. We’ve found from our Competition coilovers that this has been a welcome feature and have decided to offer in this feature in this design, also. This allows you to run a higher offset wheel with a wider tire to clear the fender lip without rubbing on the strut. Particularly critical on a WRX wagon.

• Your choice of springs (basic, Hypercoil, Swift). Whether you opt for Hypercoils due to their guaranteed precision and accuracy or Swift due to their smaller wire diameter and lighter weight, the decision is yours.
