rear spring rate

Does anyone know what the stock rear spring rate on a 4th gen is. I see a lot of people having success with these. I am using BMR's that are 170 lb and wandering if it would be worth making a switch.

Thanks

Duane

Stock v8 rear is rated at 113.6 lbs/inch. Ours tested at 110lbs per inch. BMR's are not linear and start around 100lbs/in, then 12x, then 160lbs/in...their "working rate" after the car sits down on them is 160lb/in.
