I've just had a full body kit upgrade and the car looks great! However, the additional weight of the extended spoiler on the tailgate is enough to prevent it from staying open and I'm currently propping it up with a wooden pole which is really embarrassing.
I can't see any gas struts, only the hinges at the top of the tailgate.
Does anyone know if there is a way to increase the tension in order for the tailgate to remain open.
Thanks for your help!
