I'm replace that already, Yes you right that belt kits without the belt tensioner, need to order. Now the belt is very loose I don't know why VBC do it like that!!
After that FF17 I don't think I 'll buy another VBC product!!
可考慮改裝成FF12, 以下零件FF12和FF17都相同
Center Drive Shaft Set B-02-VBC-2017
FFTwelve Motor Mount B-02-VBC-2029
FFTwelve Front Gear Box (A) B-02-VBC-2023
FFTwelve Front Gear Box (B) B-02-VBC-2024
