Yes! Steeda adjustable suspension, as well as items like braces and jacking rails are strapped to the underside of your car and can be subject to very harsh conditions with water, grit, dirt, rocks, salt and more hitting and coating them.
Even powder coating cannot resist a constant beating and so you should periodically check your underside components as part of your service and maintenance schedule and clean and protect as needed, and lubricate parts that offer adjustment (or you will find they dont offer adjustment any more after a while!). The worse conditions you drive in the more frequently you should check your parts
