STEVE-O Posted April 14, 2014 Report Share Posted April 14, 2014 Had to pull my stock one off while I pull my trans so decided to upgrade it now. Anyone have any hands on experience as to what company makes a better arm? I have been looking and they all seem very similar and with almost identical end results. Anyone suggest one over another for any reason such as price? installation ease? actual performance differences? TIA Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted April 14, 2014 Report Share Posted April 14, 2014 I like the BMR unit I have. We installed a Spohn in Tina's car, but I don't like the harsh noises from the body-mounted version and the integrated drive shaft safety loop is a PITA.

Chadz89GTA Posted April 14, 2014 Report Share Posted April 14, 2014 Have a umi with mount relocation. Night and day difference and it was at my door the next day since they're located in PA Quote Link to comment Share on other sites More sharing options...
Cordell Posted April 14, 2014 Report Share Posted April 14, 2014 I have a BMR trans mounted torque arm with a torque arm relocation transmission crossmember. The BMR torque arm works great on a stock rear end, but it didn't fit worth a shit on the Moser 9" I had. If you look closely at teh mounting bracket at the rear end you'll see some subtle differences, UMI and Spohn are designed to fit the aftermarket rear ends better. The other UMI components I have are really high quality and will be buying their torque arm when I get another rear. Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted April 14, 2014 Author Report Share Posted April 14, 2014 Pretty mixed as I thought it would be. But it does appear everyone agrees to get the relocated mount no matter what. I also already have a driveshaft loop so that helps a bit. Is everyone running the long adjustable or is anyone running the shorter arm? Couldn't find any real info on advantages or disadvantages to the short arm vs the long Quote Link to comment Share on other sites More sharing options...

Couldn't find any real info on advantages or disadvantages to the short arm vs the long The short arm attaches to the body and transfers more noise. The longer arm is better for all around use. The reason for the shorter one is to effectivly change the instant center for launching the car at the track, it wouldn't be my first choice for a street car. There are some decent write ups on LS1 tech about it by people much more experienced then me. Quote Link to comment Share on other sites More sharing options...

If I could redo it I'd pick up the UMI for better fitment on the rear as well. Quote Link to comment Share on other sites More sharing options...
wagner Posted April 14, 2014 Report Share Posted April 14, 2014 I've had both types on 2 different cars and now am using a long BMR relocated off the transmission. Body Mount Short: Lots of road noise but when or if you really try to get after it that's where this one shines. BMR told me they steer customers towards the shorter body mount setups when people are trying to run low 10's or high 9's. Advantange is you can really hit the tires harder with one of these. Long Standard mount: Running this right now with it off the trans and it has worked well. Better than stock, cut some nice 60' with it and not as much noise. I went with BMR because I had some store credit with them. Pretty much everything Scott said rings true as always. Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted April 14, 2014 Author Report Share Posted April 14, 2014 Looks like I will be looking into getting the bmr with the mount off the trans insted of the tailshaft. Thanks for all the input everyone. Quote Link to comment Share on other sites More sharing options...
