I'm not sure if the LSJ has the same brake parts as the LNF, but here is what DF gave me:
front
brake calipers are for a 2007-10 Chevy Cobalt (base 2.2 liter engine)
rear brake caliper for a 2006-09 Pontiac Solstice.
I would imagine the rotors would be off the same car as the calipers... but maybe not, as the base 2.2L engine only has a 5x110 bolt pattern on certain specs.
