I've bought from multiple places. MM sells them. I shop around, and buy them from whoever is cheapest, Jegs, Summit, LMR, and Brothers, to name a few. I went with tubular front lower control arms and coil overs to lose weight, and gain adjustability. You can just replace the bushings, but it's more work that way. If you're not going with C/C plates, get the poly strut tower bushings as well (I've got one car each way - plates are more precise, but bushings are quieter). Sway bar bushings will also make a difference.
