Each BMW E36 Suspension System Comes with a 5 Year Warranty:
ISC?warranties its coilover systems to the ORIGINAL PURCHASER against?
defects in workmanship and material for 5 years.

Adjustable Damping:
ISC Coilovers all come with 32 way adjustable damping that is rebound and compression in unison via 32 step adjustment.

Single Cylinder Mono-tube Design:
Large cylinder and piston design work hand in hand to increasing driving?stability and dexterity. ISC utilizes a mono-tube design damper, not?twin tube like other manufacturers. Mono-tube dampers provide consistent valving and much less potential for cavitation. They are also high?pressure to reduce body roll, and are 100% efficient through all?temperatures.

ISC Suspension offers three valving options to choose from:

• Street Comfort?is designed to feel close to OEM and is the most comfortable?valving that we offer. If you are looking for a mild drop and?comfortable ride this is for you!
• Street Sport?is designed to be above OEM, and is more aggressive and ideal for?street, drift, and occasional autocross. If you?re looking to bring your car to its limits on the street, this one is for you!
• Track Race?is their most aggressively valved and is suggested for road course,?slammed show cars, and some form of drifting. If you are installing?these coilovers on a dedicated weekend track car, this option is for?you!

Piston Rod Design:
ISC utilizes high rigidity steel piston rods that meet all race and sport?standards. ISC shafts are valved according to the spring rate chosen by?the customer. A shock dyno is used to ensure quality and consistent?results. All ISC dampers are 100% fully rebuildable.

Upper Mounts:
For optimal performance pillowball upper mounts are a great feature. ISC includes these upper mounts of all N1 Systems.

Front Camber Plates:
All BMW N1 Coilover Kits come with adjustable camber plates standard.?

Thrust Bearings:
While many coilover companies charge for thrust bearings ISC does not. These?come standard on all N1 coilovers and help to eliminate spring bind; a?common side effect of utilizing aftermarket coilovers.

Sport Spring:
ISC?Suspension offers a variety of different spring?s rates. Our springs?are made from high quality SAE9254 Steel. They are dyno tested over?500,000 times on a compression inspection with less than 5% deformation.

Ride Height Adjustable:
Full?length height adjustability. Most applications can achieve 3 inches or?more. High quality T6061 aluminum allow used for all adjustment locks to provide a lightweight design that holds spring and vehicle force down.

Bound Adjustable with Separate Spring Locks:
Preload is separate from ride height; the lower you go the quality of the ride stays the same!

Adjustable Rebound & Compression Damping 

Want full control? The KW V3 gives you multiple settings for both rebound and compression. You have full access over ride comfort and handling to dial in that perfect setup. Race teams rely on adjustments to get that perfect lap time and having shock controls at your fingertips is key. KW V3 features -

• Separate adjustments for compression (14 positions) and rebound (infinite settings),
• Stiffer springs over stock for less bodyroll than the standard suspension,
• Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
• Individually height-adjustable - Front = 20-50mm lowering; Rear = 15-40mm lowering,
• TUV approved lowering range and operation,
• Expert engineering and design for ease-of-use and long durability,

Whether you track the car often or only use it for backroad carving the V3 will give you the tools to set up an ideal handling condition. You can crank it up for smooth and fast surfaces or soften it for city or rough roads. Since each shock is 2-way adjustable you can alter the front-rear balance to account for brake dive or squat during power application coming out of the corner. You are in total control! 

Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires. 

Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.

The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.

Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.

Kit Includes:

(2) Rear damping adjuster extension cables

Installation hardware and Allen key

A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.
