I have been reading the archives and am confused about what rotors and calipers will fit on my 92 400E with 17" rims. Where do you go, or how do you find out what options you have. I noticed the 500E rotors are not much more than the stock 400E rotors from PartShop. Are they larger in diameter?

Sorry if this is a repetitive question.

Thank you,
Brian W.
