The new ISC N1 Coilovers offer a sporty feel that can be taken to the track but driven on the street comfortably everyday. With 32 way adjustable dampening that will operate smoothly on all road surfaces, they also include precise control dump valves, expansion and suppression of the shock adjustments. Made with highly rigid steel piston rods that will meet race/sport standards, the N1 coilovers are very durable and made from SAE9254 steel construction that has been tested over half a million times with less than five percent deformation. A single large cylinder and piston design will advance stability on and off the track, held by a T6061 aluminum bracket specially anodized to prevent corrosion and rust. Upgraded Thrust Bearing Kit are included on all N1 ISC coilovers to eliminate the chance of the normal spring bind that you would get on most aftermarket coilovers.

ISC Suspension N1 Coilover street version for 2015-2017 Mustang GT

Here’s my review on these ISC N1 Coilover street version for my 2016 Mustang GT Performance Package (PP). I would like to thank Josh from Import Image Racing for his excellent customer services.


I set all four dampers at 22. Has a smooth ride but yet very firm when when the suspension travels. Did not bottom out on unexpected uneven roads. Have not yet track the car but I can definitely tell it handles better than the PP suspension. Lowered my Mustang.


Wish it was labeled on the coils to take the guessing out. Example which side facing out. The rear coils/springs was set at the highest setting and the rear sit very low almost 2 inches lower than stock. (Rear PP wheels with 275/40/19 tires)

Front can be lowered down to match the rear but will require 5mm hub centric spacers otherwise the front coils will rub the inner sidewall tires (PP front tires 255/40/19).

I’ll rate these coils at 3.5/5 because of the rear. Overall I’m happy with these coils.
