Learn More about R3
In all Nitron systems you find exquisite machining and finishes, carefully detailed components and a COMPLETE system with nothing left to fetch or find. Quality at every level inside and out down to the oil selection. This results in reliability, strength and performance that are impossible to match at this price point and easy of use.
The Nitron R3 delivers ultimate performance through a unique design that offers drivers a wide range of adjustable damping control at the price point of most 2-ways systems or better!
The R3’s 3-way system has a single rebound only adjuster (no cross talk) and two compression adjustments (Low speed bypass and a high speed poppet control). For R3 systems purchased through Inertia Lab directly a considerable amount of tuning setup and assistance is offered including initial setting suggestions and education on how the system works so that you are as equipped as possible to decide what to adjust and when to do so. We try to take the sting out of multi adjustable setups allowing more people to take advantage of them by knowing they are always going to have help. The Nitron R3 leaves nothing on the table, setting multiple records around the world. This is the imminent suspension system for all out performance.
Designed to withstand the abuse of the track, all Nitron systems are also reliable for the street enthusiast who drives long miles on public roads. Whether you daily drive or track your setup the full range of Nitron systems are up for the job in all environments.
Droplinks included.

Frequently Asked Questions
Which spring package do I want?
Which spring package do I want?
The Performance Street spring setup is designed to provide a sporting, but comfortable ride. Performance on the road is very high, but may require the dual purpose springs if you intend to track your vehicle regularly.
The Dual Purpose spring setup provides track support for the enthusiast who drives to the track or still uses the car on aggressive drives. HPDE on 200TW tires are ideal here and modest or no aero cars. This will help keep tires from edge wearing on track due to excessive roll without killing roadworthiness. Ride will be more taught, but can still be reasonably smooth.
The Track spring setup is for those who use slicks, have a bit more aero and just bias more completely towards track performance. Obviously you can drive anything on the road, but you will have a firm ride with the track setup. With the damping control offered by Nitron, this is not always a bad ride which matters over curbing and on bumpy tracks.
Do I want divorced or coilover rear springs?
Do I want divorced or coilover rear springs?
If you are asking yourself this we suggest keeping the divorced setup. This retains the major loads where they were intended and does reduce friction by eliminating the sideload of the spring on the damper shaft. Coilovers can be more tightly packed on some models and sway bar, axle or control arm clearance is not always ideal or perfectly predictable. They do sometimes allow a simpler install/spring change and easier access to the spring perches for adjusting height (think race team making constant adjustment). If you don’t KNOW you want coilovers then retaining divorced springs is the way.
What about an R2?
What about an R2?
An R3 or eR3 can be ordered as a 2-way with one compression adjuster instead of the high/low speed adjuster pair on the standard R3. There is little difference in componentry and so no cost difference, so you are merely losing an important adjustment for the same price. Given the market value of the Nitron system this is still cost effective for people who have class limitations, but if you simply think “it’s too much”, “I’m not that good” or “it’s confusing” then let us help you set up and reap the value of the extra adjuster without losing it at no added cost.
