Actually, the rate will increase, as stated below. The CAPACITY will decrease, not the LOAD. Since the car is lowered, raising the camber rate, one might make the case that the load is slightly increased, as well -- at least for same sized road undulations.

And since you're now operating at a higher load point of the spring's lowered CAPACITY, the ability to absorb "hard bumps", a.k.a. CHUCK HOLES to us midwesterners, will disproportionately decrease.

Look very cool, though! But those of use who have already BENT custom aluminum-bodied $trut coilover$ on the street will submit; sometimes there is a price to pay.
