Chevy stuff would probally work but its ALOT of additional unsprung weight.Toyota brake parts might be better suited.
The stock subaru caliper weighs 7.6 lbs while its rotor weighs 9.19 lbs so 16.79 lbs per side.By contrast a 87 1500 chevy caliper weighs 9.95 lbs but the rotor comes in at a massive 19.18 lbs so 29.13 lbs per side.finally 87 ifs toyota caliper is 10.65 lbs(2 piston design vs the 1 piston of subaru and chevy) while the rotor weighs 13.89 lbs totaling 24.54 lbs per side.
So the weight difference between toyota and chevy stuff isn't that big compared to each other both are still almost twice the weight of the stock stuff.I would put money on the toyota brakes with the two piston caliper stopping better of all three combos,but if you like to ride your brakes like an old lady the chevy stuff would probally work better due to the sheer mass of its rotor would be better to deal with immense heat.
toyota has a better caliper that offers more clamping force but chevy has a better rotor that would better resist the heat generated for long continous braking.
better still the brakes off a 4wd nissan D21/pathfinder would be best because the caliper weighs close to stock(dual piston) and the rotor is 16 lbs so you get the better clamping pressure with more heat capacity.
