Product Spotlight: ISC Suspension-NA N1 Coilovers

ISC N1 Coilover REPRESENTATIVE PHOTOHello folks, to continue on with our ISC Suspension product spotlights today we have the ISC N1 coilovers! Specificlly the one that I will touch on is the N1 Coilover for the BRZ and FRS platform. This platform is one of the newest coilovers that ISC Suspension-NA had produced. This product still features their dyno proven valving and double o ring technology.

What does double O-Ring technology mean?

Double o-ring technology essentially means that wherever there would be an o-ring on the internals of the shaft, there are 2! This helps to make sure that there are absolutely ZERO failures and ZERO leaks.

Some of the other great features of the ISC N1 include separate pre-load and separate ride height.

What does this do for me you may ask?

Many coilover systems in the price range that ISC’s are at usually have pre-load and ride height in the same adjustment. What this means is that the lower you bring your vehicle down, the worst the ride quality gets. With ISC’s coilover this doesn’t happen and you can enjoy operating your vehicle without having to worry about it becoming impossible to drive and tolerate!

There are many other features of the ISC N1 coilover system, and to read more about them please see the official product description fro ISC Suspension-NA’s site. To purchase a set of coilovers please visit our store here: Coilovers
