12 bolt = lowered probs??
12 bolt = lowered probs?? I can get a deal on Currie Axle 12 bolt. I am a lowered car and wondering if this will cause any probs...especially T/A and sway bar clearance. Anybody lowered with 12 bolt experience is appreciated....... THANKS!!!!
I had a 12-bolt in my car with the same springs (Strano's) and didn't have any clearance issues. The only issue I had was since the axle tube is larger, it put the sway bar end links at an odd angle and they kept pinching the bushings out. That was easy enough to fix with longer (about 5/8" longer) end links.

I removed my Strano lowering springs because of a Spohn TA. The TA bracket kept hitting the tunnel on the driver side. So severe it almost pierced the flooring.

The TA bracket can be trimmed which might provide additional clearance but I haven't tried that yet. The upper plate on both the UMI and Spohn TA rear bracket uses the inner bolt holes for mounting rather than the outer bolt holes. So the outer edge of the TA bracket plate can be trimmed some. Trimming might be a winter project because I would like to re-install the Strano springs again.
You also have to bend and reroute the brake fluids lines as the 12 bolt housing is bigger (higher) than stock. The installer literally jammed the brake lines on top of the housing with no regard for clearance between the housing, the brake lines junction, and the floor tunnel.

Im running Strano springs and a SLP TQ arm and have a MOSER 12 bolt. No problems here. Before Had QA1s and varied ride height to where I liked it and never a problem-except for the shocks. Main problem I see with anything aftermarket is a poor install. The shop I left my car with while I was over in Iraq did **** poor work. So I had to redo their work. On a aftermarket TQ arm-face the head of the bolt away from the prop shaft to give more body clearance. the bolt threads will not hit the U-joints. And if it looks too long and will-get a shorter bolt and thinner nut. SLP and Random technolgies TQ arms are very simiular in design. UMI and BMR are made to fit stock/12 bolt and the Nine inch. The rear Mount on the SLP and Random tech TQ arms are smaller in size than BMR and UMI. Meening not dual drilled. if its drilled for the 10 bolt-it will fit a 12 bolt.

So even though the inner bolt holes are used when mounting either the UMI or Shohn TA on a Moser 12 bolt there are still four holes requiring a larger plate (bracket).
Although not very clear this pic shows how far the Spohn TA mounts off of the driver side of the Moser 12 bolt. And as you can see the two outer bolt holes are not used.

I know about the Spohn TQ arm as well-I have run one before. And about to reinstall it-its a mid mount- Most people dont like the idea of further fabrication. Such as clearancing the tunnel for more clearance. I would understand on a Classic. But these cars are very far from that. Thats just my thought tho. It can be done to look factory. My suggestion would be a TQ arm that isnt as bulky as the Spohn-UMI or BMR. And if he did happen to have one-have it modified to fit the tunnel. because mine was not assembled correctly-the bolt hit the tunnel a little, My concern is it ripping the sheetmetal or stressing it when It would hit. I agree with you on the rear mounts bulk being a problem. I was concerned about it to-slipped my mind I had fabbed up a rear mount that would work better.
