well i just got my Mcgaughys lowering kit. 2/4 drop with the spindles shackle and hanger kit. got a question though.

the spindles i bought fit rim sizes 17" and up, and i wanted to install everything on my truck before i get my rims and tires which are going to be 20's. i have 16" rims, will the spindles work with the 16's? is it a good idea to just go ahead and install them? im not going to install them until i get out of school. which should be a week or two in may. any comments would help. thanks
