Does anyone know a website where I can look up laws for each state pertaining to car modification laws such as lowering limit, decibel limit, laws on neons etc. I know some of them are mentioned in these threads and I can easily find them, but I just want to see other modification laws particularly pertaining to California, cuz that's where i am at. any help appreciated thanks

Check the "vehicle code" box, and search for whatever you want.
