I first have to say, I've order quite a few parts from Detroit Axle and all of their parts have treated me well. They're a very responsive company, and as far as I can tell, they haven't cut corners on quality but are still a very economic cost effective solution. When I ordered my brake kit, I just expected the rotors, pads, and maybe hardware(which was included). But I went digging after receiving another package and realized that they were sending brake fluid and cleaner. All of that for 55 dollars!
I love this company so far, they seem very honest and communicative.
