[Are TRD wheels available to fit 19 Highlander?]

Yes, I’ve looked at a few other brands of wheel. But I’m interested in a 19” TRD Avalon wheel from Toyota, it has a 45 offset  and my vehicle has a 30. 

[Are TRD wheels available to fit 19 Highlander?]

I’d like to replace the black SE stock wheels on a 19 Highlander with stock TRD wheels. Has anyone at all tried this? Where to find? What location or link for info? Dealers won’t help and I can’t find anything online where folks have done this. Will Camry/Avalon  TRD wheels fit?

Also looking for a TRD muffler and tip for same 19 Highlander. 

[Exhuast Tip]

Me too. I’ve asked service/parts at dealer and no suggestions. Not sure if Camry or Tacoma tips would work. Need to measure the outlet from muffler and consider the angle too. I’m wanting a TRD muffler too maybe. Also TRD wheels. 🤷🏼‍♂️

[New owner here, does the third row lays absolutly flat?]

Third rows lay almost flat, just a bit off level in my ‘19. 
The ECO light lets you know you’re not driving like you stole it. It stays on when driving conservatively. 
I don’t have apple csr play on mine so can’t answer that.
