I have Nitron's R3 kit and am loving it, their build quality is simply jaw-dropping.
With a coilover rear end, I hope you're running a cage with rear shock tower bracing.
Looks to me like your kit would be difficult to adjust front and rear compression damping without first removing the wheels because of the piggyback shock configuration.
As these kits are fully custom, I ordered mine with an external shock reservoir connected via a hydraulic hose as an alternative so you can place the reservoirs anywhere you wish for ease of access.
