Yes but weigh the diff complete with std wheels and tail shaft, then weigh your vl with intended wheels tail shaft etc, that alone will add 40kg. so a ke30 sedan is 890kg add 35kg for wagon, 40kg for diff, thats 975 kg straight up, so unless you can strip all of the stuff your going to replace ( all you will have is a body with trim) tell me how your going to loose 100kg. maybe no interior, plastic windows, kevlar panels ( fibreglass doesn,t really save much) you could do it but you wont be able to register it, i think 1060kg, OKE020 says his is 1200kg odd
