I recently bought a set of new T Type center caps for my Riken honey cone style wheels. I have issues with the new caps popping off under the right conditions (bumps) nothing major. I do not understand why this is happening but I did notice the original caps had electrical tape around them where they went into the wheels. I thought this was done because of the original cap age. As a side note, I did recently swap bad Monroe shocks for Bilsteins which are somewhat stiff. Might this be the cause, any ideas?
