OK maybe engineered was a stretch. Based on info in the product desription it would suggest that the STR.T work well with, compliment, and improve handling of cars with lowering springs. This is not implied with all shocks and struts; therefore, my conclusion was some design considerations could have been included for cars with lowering springs.
