I search but haven't found a solid answer. Would a complete RAv4 steering wheel and airbag work in a SC400? I know people use the Rav4 airbag with the is300 wheels but the Rav4 wheels are way cheaper then is300 or any other wheels that I've seen.

Rav4 Steering Wheel

 

From what I know, all Lexus / Toyota wheels are interchangeable. It depends on the airbag. I think you'll be good.

I'm sure an expert will chime in

 

Interested to know as well.. I too am looking for a new steering wheel setup for my DD in black like the IS3 look but the damn is3 air bag with the hump is not doing it for me. wondering if a different bag could be used with the is3/orolla/celica etc. wheel

 

Well people use the Rav4 airbag with the is300 steering wheel. I was just wondering if the Rav4 steering wheel could be used as well.
