JOM coilover adjustmen

[AbbasTrd]

It’s my first time posting here and I wanted to ask how do you adjust the rear ride height on JOM coilovers. I bought the car couple days ago and didn’t realise it had coilovers until I got tyres put on this morning. The front ride height is fine I just want to lower the rear by a couple of inches. Is it possible to adjust the rear ride height on the JOM blue line coilovers?
