That doesn't even make sense. why they would need to modify anything?? They already do a manual type. Besides the rears are just r33 gtr bodies with an s14 top plate (and valving for stagea). All the parts would have been on the shelf. As cheap as the Chinese stuff is (and having tried nismo's, tein's, hsd's and bc's) they are just as good as the tein's for the street. But nothing compares to the nismo's !!
