NNoooooooooo don't do it. You will never be able to live with the shame of having torago wheels on a RA28.
My last RA28 had torago mags and I can't think of anything that could look worse on it. I am still getting harassed by my brother about it, 10 years later.
Incedently 10 years ogo they cost $330 each new from toyota. Don't ask me why I remember that.
