Grrrr...just had my Tokico illuminas and springs installed. Anybody notice how cheap the adjustment screw is? Mine are made out of plastic! So as I was trying to adjust the rear one, it broke off and now its permanently stuck on 5! The ride sucks. I can't turn the adjustment anymore because its all grounded up and broken. Why didn't Tokico make this fitting out of iron or steel?? I noticed that when I try to adjust it, the fitting turned but when I let go, it seemed to torque back to its roginal postion. I could turn it maybe 45 deg but then it wouldn't snap into place like it should. It just torqued itself back to its setting of 5?? Do I have a defective one? What's the procedure to get a new one? I know Tokico has a liftetime warranty. I was adjusting the other ones and they almost broke too. I got 3 up front, and a 3 and a 5 in the back now. This sucks.
