Im trying to adjust my tein flex coilovers to feel smooth like it wasn't lowered. I know this is virtually impossible because I almost have no wheel gap on all 4 corners.

But my main question is, do i set the front coilovers stiffer than the rear coilovers?

 

the springrates + lowspeed dampening cause the harsher ride, not the ride height. With stiffer springs, more shock from the bump in the road goes into the frame instead of the spring as it's harder to compress.

The only way to adjust it, would to get softer springs or lowering your dampening, however if your shocks are set too low, you're going to get a bouncy ride.
