Does anyone know what the staock spring rates are for a 2004 sedan with the standard, non sport, suspension? I am looking at either new springs or coilovers, and would like an idea of how they compare rate wise.

 

it's stickied at the top of this forum:

Thanks. Didn't look far enough down the list when I did my search. Now second question, how far can you lower a sedan, without needing to go to some type of camber correction?

 

less than .8 inches, you might be aight...there's a ton of stuff on here. type "lowering" or "springs" in the search string .

 

Each inch changes camber ~~ 0.83 degrees..............the question is how far below nominal your oem is.

Don't assume anywhere inside the very wide oem warranty range is ideal.

Tires are usually designed for no more than 0.5 degrees negative camber to optimize braking and life.
