    ISC Suspension N1 Street Sport Coilovers ( Part Number: S007-S)

    Hello I just wanted to drop some knowledge on these coils. I have installed a bunch of this specific model on this chassis for friends of mine (I've personally had them on other Subaru chassis) and they awesome. The install is very straight forward and easy as Subaru suspension is real easy to remove and install. They definitely stiffen up your ride but are still smooth and comfortable. Just make sure you set the spring preload correctly and add some anti-seize to the threads where the collars are and enjoy.

    May 28, 2019: (3/5 rating) Finally got around to getting these installed. I can't tell the difference between these set and OEM setup. I have the dampening to 25 / 32 and still feels like OEM suspension. However the life time warranty will help over time. Also, I wish RSD would stop censoring reviews. May 4, 2021: (4/5 rating) After having this set of coilovers, I'm very glad I purchase them. The front passenger shock is now failing. The coilovers are 32-way adjustable but for some reason, I can only adjust the front passenger 24-ways. I reached out to the tech support and they quickly RMA'd me a replacement shock. I'm very glad I got this since they come with Life-Time Warranty! As far as performance goes, do not expect MAX STIFFNESS. They are more stiffer than OEM. Suspension really comes together once front / rear sway bars are upgraded as well as control arms. May 22, 2021: (1/5 rating) Recently, the passenger side / front coilover failed and ICS sent me the replacements parts to rebuild the coilover. So I decided to pay a local reputable professional performance shop to rebuild a damaged coilover and adjust height. What I thought was going to be something straight forward, turned out to be a nightmare. Found out the rear coilovers were complete seized up. No adjustment was possible just after 3 years of purchase. Then, I found out ICS shipped the coilovers with the top hats for front coilovers installed incorrectly, even though the instructions say they are sent already installed and pre-loaded. The adjustment knob could not be removed from the coilovers. They are completely seized. So the coilover that was rebuilt is set to soft setting and I cannot adjust until I get a replacement adjusting knob / screw from ICS. The knobs are supposed to come off easily but they don't move at all. Considering I bought these in 2019 and already having this many issues, I was advised to trash them and get a new set. What a complete waste of money!

    • Q: Isc drop height  teninch5152 years ago

      Do these really drop 3in in the back? I’ve had bc, raceland, and now megan racing coilovers and the backs never lower as much as I’d like. Not trying to waste my time
    • Q: Height  tim_89115692273 years ago

      Do these come out of box set to max height? Or do they have to be adjusted right out of the box?
      • 0 of 0 people found the following answer helpful

        A:  You will want to adjust these once they're on your car/out of the box, and the kit does include the proper wrenches to adjust them.
