Truck? What truck?!
Needing a camber kit depends on the distance dropped, not the particular spring. It is generally thought that anything up to about 1.5" does not 'require' adjustable camber arms, although best practice is to install them, regardless, if you want truly proper camber. Of course, YMMV.For those who have Swift springs for a 14-15 Si sedan, did you need anything extra other than getting an alignment? Just checking to see if I'll need a camber kit or anything like that.
