I bought a set of Ground controls with KYB AGX shocks off of someone from the internet and they didn't come with the upper urethane mounts that go on top of the spring. I have a set of maxspeeds that have the mounts though. Should i use the mounts off of the maspeeds on the ground controls or should i just leave it without the mounts. What do they do? I am getting it all installed this thursday finally.
