H&R is a respected brand.

With RWD, 1.5" drop is about right for the street...and it allows use of stock shocks.

Companies keep their spring rates to themselves, but the same spring rate as stock is hard enough unless you are getting airborn and need hard shocks to keep the airborn body from crashing onto the suspension.

Otherwise stock spring rates are designed to support the car. You are not running Baja and don't need hard springs.
------------------------------------------
17 year olds think hard shocks substitute for anti sway bars.
There are PAGES written about why anti-sway bars keep the car from leaning, and hard springs just beat up the car.....which is what another member is also saying in this thread.

If you are in FL, we can use my spring compressor.
Most autoparts stores rent or loan spring compressors.
If a spring has the shock bolt going verticle through the middle of the spring, (sometimes called a "coilover") get a spring compressor that will compress the OUTSIDE of the spring, otherwise the inside spring compressor will interfere with the shock bolt that goes up the middle of the spring and won't work.
