I've had Cusco chassis braces on my MR-S as well as US made and Taiwan/Chinese made. The Cusco parts had better fitment and were much simpler in design. They were made of steel whereas the Taiwan/Chinese knock offs were of some sort of lighter material. The US made parts were much heavier and had the over-engineered feeling. I bet the Cusco sways are not going to be as thick as other non-JDM aftermarket parts, but that may give you more flexibility in terms of the type of driving you want to do.
