I'm in the process of doing some Steeda full length subs, J&M lower control arms and an Ultimate 8.8 rear diff cover on Pete's car. I like these Steeda subframes. They come with tq box reinforcement plates for the rear and everything fit pretty good except for my fatass under this slammed mustang! I think I need some taller blocks! lol I have the Driver's side sub done. Tomorrow I will start on the passenger side. I should finish it up sometime on Saturday and I'll have father's day off. Tq box plate Ready to be tacked Seat support bracket, bolted and welded. Subframe is in. Just need to prime and paint it.
