anyone know where I can buy lowering springs for my bonneville?

This has been talked about many times and as of right now I believe the only way to lower our cars is to go with bags. I may be wrong, but I believe I'm correct. But it depends on what year your Bonneville is.

Please put your year and trim level in your signature. It would help greatly.

You can get custom springs from www.coilsprings.com.
Paulnold dropped his 96-99 on them first and I dropped my old 95 on them after.
No one has used them for 00+ or pre 92.
Definitely get the coating if you do get them. I was sorry I didn't.
