the tools that come with the kit are not suitable for building the kit you need metric tools and a 5.5 nut driver ....be careful when you try to adjust the droop screws in the front....if you dont have a 2mm ball driver you could easily stripe the screws .....i drilled a hole in each upper front arm so i could easily access the droop screws worked pretty good ....and make sure and locktite any screws that are going into aluminum ...
