question on hwy cruising

i am worried about the all wheel drums and am looking into discs for the front just looking for sbp discs and like i said its not crazy heavy(600lb enclosed trailer,430lbs bike, about 15-20 gallons of fuel and maybe 150lbs of tools) i figure id round up and assume 2000lbs for the trailer. the car already has air shocks on the rear. but i figure i have about 4 months till racing season restarts :blob: and then i will have to worry about towing
