I have a 2020 ORP non KDSS- Lift specs in my signature. I turned off lane departure warning first week. I still occasionally get a brake warning at appropriate times. Radar for cruise works perfectly as does auto dimming brights.
My thoughts for you.
The TRD Pro comes from factory 1” higher in front with slightly cut bumper to prevent rubbing. The TRD Pro also has perfect functioning Safety Sense. Consider Bilstein or Eibach shocks all around with fronts on the first perch for+ .85” lift. Should give you that TRD stance. With trimming should be good for 275’s and I’ve read of others running 285’s with that setup. Take your time and enjoy the process.
