My car and torque arms are pissing me the **** off. Put a 9in in my car about 2 weeks ago. I messed around with my umi non adj. torque for over 4 hrs and came to the conclusion that it just wouldn't fit. Meanwhile, the stock one slips right on and is installed in a matter of 10 minutes. Then last week, I traded away my UMI + a good amount of cash. Tonight I go and try to install the BMR adj. 1 I bought, and it doesn't fit! I'll go out and take a picture in a few. The BMR one was adj. to match the stock one side by side. I was able to hammer it on to the 9in housing(shouldn't have to do), and the holes are about an 1/8in off. WTf, am I doing wrong? At this point I've pissed away so much money on torque arms only to find that stock is the only one that has worked so far.

I have a mosere 9" and a umi adjustable arm, no issues at all.

is it trans or tunnel mounted? The adj. one I have is a BMR. I have the technique down it takes to get the pinion at the right angle so that it'll let the torque arm slide on and off, it just seemed like the mounting flange of the torque arm will not allow the torque arm to move far enough to the center for the bolts to line up.

i have the crossmember mounted arm, adjustable.

I have heard of the arms not fitting and needing grinding of the housing or arm to make it work, It could be a issue with the torque arm mount on the axle as well, the stock arm may fit because its thinner and more flexible.

I wouldnt even bother with the non adjustable arm, its worthless on anything but a stock vehicle at stock height.

as for the bolt holes in the BMR arm, are there 2 sets of holes or just one? I know my UMI arm has 2 sets of holes, you couldnt use one set of the 9" rear unless you cut the webbing of the 3rd member a lot. I just had to grind a tiny little bit in one spot fopr the other set

yea, I'm gonna have to grind a little bit of the torque arm or 3rd member. Just don't have the time to mess around with it tonight. Maybe tomorrow I'll see what I can do.

if you need a electric grinder or air die grinder i can lend you one if need be. just give me a shout. i could drop it off on my way to work or back from work.
got a plasma cutter too, but i think you might go overboard with that....ha.ha

thanks. I'll let you know how I make out. Got a pretty busy schedule for the next couple of days, so I may not get to it until next week.

the nice thing about the spohn setup is it has 2 sets of holes for that reason. maybe consider buying a spohn? Ive heard fitment issues with the other manufacturers with aftermarket rears.

I just finished intalling a moser 9" and a Spohn adj. torque arm ,crossmember mount. The Spohn mount has 2 sets of holes ( 1 set for the 9" ) I mounted the TQ arm to the rear,than to crossmember, than moved the crossmember into place and bolted it up. It took a little effort but went into place. Hope this helps.

i just read some horror stories about the tunnle mounted t/a ripping the brackets right off the floor pans.... because that tunnle brace is only held on with those little bolt plates that are spot welded to the floor.... makes sense that hard launch might tear that out... i might go with the trans crossmember set up..... is that what your doin vin? and then ill just get a safety loop separate...

nah...I'm going trans mounted all the way...as in stock location. Gonna try and snap the tailshaft off the trans on a launch:nod: I may end up selling my exhaust so I can actually run something that's safe.

yea from what im told... x-pipes give alot of extra power though.... but some power loss is better than breaking stuff....

I've got way too much money into the y-pipe setup to justify selling it anyway. Between the catted y, custom welding, e-cutout, etc. Adding it all up is close to $1k and that's excluding the muffler.

If you have three point sub frame connectors then a tunnel mount would not have much to worry about.

This is fail.

Three point SFC are ftw. Do it Vinny.

And again, cats are ftl. :nod:

really? is that what the trooper said? cats ftl? :lol:

i'm a little pissed about the chassis mounted torque arm bs. maybe the braces can be fully welded? eh brandon? i gots a welder! and throw in the sfcs? ehhhh brandon? :lol:

transmaro93
07-25-2009, 03:04 PM
you have a welder...? what kind brand and type... and whats it capable of... didnt think about 3pt connectors... yea with those the tunnle mount would be fine.... i only have 2 point connectors though...

yea, I'm really thinking about redoing the exhaust...I'd be loosing so much money it's not worth it though, but, if it saves the trans it might be worth it, but the trans is still making noises so who the **** knows what's with it.

If its a good setup, you can prob make your money back.

put your setup up on tech for trade. thats what i did. i got cash on top of a full exhaust too :nod:

update- called BMR to make sure it was a "common" problem to have to cut up the torque arm mount to clearance it for the 9in and the tech's responce was "the 9in housing varies so much that it is common to have to trim them on the s60, 12 bolt, 9in..." so after about an hr of cutting the torque arm it fit. It's so nice to not be driving on stock torque arm now...can't wait to hit the track.

I have a bmr ta and mine was a b!$#@ to put on with my 9 inch but I managed to get it on without modding anything. You'll find out soon that on big bumps and hard launchs T/A mount on the rear is gonna hit the floor/trans tunnel if its not clearenced at all.

yea, I clearanced it with the BFH mod. I think that was the majority of my problem from the start. O well, the chromoly piece is definitely lighter than stock now :D

yup i has holes in the floor between the rear seats

//<86TA>\\

mine rubs the floor between the rear seats, but only because i was able to use the outer most mounting holes, keeping the arm as far centered as possible. If i used the other set, it would be a hole. I do however have a hole behind the rear seat where the top bolt for the torque arm mount bracket "clearanced" the metal right above the tunnel hump area.
