ok, i know that the spoon jdm itr calipers fit on the prelude, so...here's the next logical question. are the itr and lude brakes the same, both rotors and calipers? would it be possible to take itr aftermarket rotors and throw em on a lude

 

yes, on a 5th gen, it's all interchangeable..

 

woudnt that be a downgrade. because of the weight differences. correct me if i am wrong please and explain why
