2016 taco sport 4x4 long bed

Does anyone know the ome front coil rate on a stock 2016 taco sport 4x4 lg bed. I want to alter the suspension in the front and rear to get a softer ride. I don't do off road, mainly all hwy driving.Do I need to change the coils, springs and shocks or just the shocks. Need advise

 

I would change the shocks out with some stock TRD OR's. They offer a very compliant ride (too much so for some of us). You should be able to find some low mileage take-offs on here for pretty cheap.

 

The stock Sport suspension isn’t that hard. What tires are you running at what pressure? E load tires will be hard.
