So I bit the bullet and bought a 6 inch BDS lift for my taco. I also got a set of 315/70 R17s to go with it. Im running stock FJ crusier rims right now from the first or second year they were out. Ive been reading that you need 4.5in back spacing. I know enough about all this to get myself in trouble. So are my current rims gonna work? And if not I saw a pair by fuel I liked. What offset or back spacing do i look for when ordering? Also if anyone else has done a BDS kit how hard is the install? Are there any problem areas post install to look out for? Im reading about this shudder in first gear kinda got me spooked.
