Eibach is one thing but the sportlines are NOT a good spring. They are too soft and way way too low for stock shocks.

TEIN are supposed to be good. Spoon Sports are supposed to be good on Stock shocks (I am not a very big Spoon advocate). Also look into KG/MM springs this is a compang not a measurement.

Look into Ground controls. They have height adjustment and they have nice Eibach ERS (linear rate) springs.
