Well im probably going to be doing some HPM subframes on my car...they are zinc coted which are a plus...i know they are probably nothing near the MM but from the 3 shops ive asked....they have to modify the tranny crossmember in order to fit them....and for the HPM ones no modifications are needed...i got quoted 200 for everything for the HPM and 341 for the MM full length....whats do you guys think???
