ISC N1 Coilovers Subaru Models



The ISC N1 Coilover system is the optimum suspension tool for improved handling for your street, track, or drift car. This product is perfect for someone looking for performance, adjustability, and other high-quality features in a package that will not break the bank. ISC coilovers are also 100% rebuildable! ISC Suspension utilizes some of the best modern engineering techniques and suspension design. ISC has been present in the world for over 13 years and has accomplished drift, road course, street, and other various podiums alike. Over a decade of experience, knowledge, engineering, and feedback have shaped the ISC N1 system into what it is today. All ISC Coilover systems are proudly serviced and distributed in Gilford, NH.


The ISC N1 Coilovers utilize a large cylinder and piston design work hand in hand to increase 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. Our larger pistons also allow more oil which provides better damping control and the ability to absorb higher forces. All ISC Dampers also utilize a double o-ring to prevent leaks.

Rear Camber Plates: On applicable models Rear Camber plates will allow for easy adjustment of camber on the rear coilovers. If this option is selected ISC will do the hard work and assemble your set so that your coilovers come ready to go! Camber plates are not available for 08+ Impreza, 05+ LGT or 09+ Forester due to the two bolt upper strut mount design. 

Rear Extenders: Rear Extenders allow for easy dampining adjustment of your rear coilovers. 

 Coilover Covers: The ISC coilover sleeves (Patent Pending) help protect your coilovers during harsh winter months. Made of 3mm neoprene these shock sleeves shed water, and eliminate sand/dirt/salt and debris from damaging your threaded shock body and corroding your springs, as well as protecting your seals. Multiple sizes offered.

    Beautiful product. Ride quality is amazing. Bought rear camber plates, rear extenders, and covers. All installed easy! Waiting till the winter season to use the covers. You can't beat the price and 5 yr warranty! Very impressed and would recommend this product! (Posted on 6/2/2017)
