torque arm: long/short & relocation with S60 install ?

torque arm: long/short & relocation with S60 install ?
considering replacing my rear with a strange S60 and the BMR 3-hole LCA brackets are recommended. That got me looking into torque arms and torque arm relocation cross member.
fwiw i have UMI adjustable LCA's and an UMI adjustable PHB that I can put back on the car, along with UMI bolt-in subframe connectors.
Came across threads about a long versus short torque arm, but I do not see long or short advertised on the torque arms by BMR and UMI currently.
If I get a replacement torque arm and do the cross member relocation thing, do I have to be careful what I buy? I don't want to buy stuff and not have it fit.
The other thing is i'm looking for good road manners and quiet vibration free operation. I get the impression all this stuff is going to be a little worse than stock and I suppose that's ok, but i DONT want the all out track setup where there will be lots of vibration and noise if there's such a thing. Car is a daily summer driver so if I put the money into a new rear I want to do it right once.
thanks.

You said two key things: good road manners and vibration free. That screams long style torque arm. The stock length torque arm is best for both. The short style torque arm doesn't allow the same rotation of the axle as the long one does, limiting max handling manners. It also is poly mounted right into the body, which will bring vibrations.
I am running a UMI adjustable stock length torque arm. I love it. It made the car feel way more solid, but the only way I would recommend a short style torque arm on a street car is if you only care about straight line acceleration at the track, in which the short arm would shine more.

Definitely stick to the full length torque arm with a torque arm relocation crossmember. This setup will keep the added noise to a minimum and give you the performance you are looing for. The nice thing about this setup is not only will it work well for handling but it can also be set up to work very well at the track. Let me know if you have any questions are if there is something we can help you out with.

Sorry don't mean to hijack this thread but I have s few questions about the adjustments on the relocation crossmember. I know moving it up and down changes instant center but which way does what. And if I lower the car with springs do I still want to start in the factory location.

Moving it up moves the IC upward and rearward. Up the whole way is best for drag racing. If you lower, it's ok and beneficial to raise the nose as far as possible except if you have a non-adjustable torque arm. If non-adjustable, the front mount helps determine your angles. If you have an adjustable one, go as high as possible on the nose and then reset pinion angle accordingly with the lower adjuster.

Thanks Ramey. I got one of your adjustable ones. Just got it in yesterday and it looks so good i cant wait to get it installed. One more quik question: I noticed the bushing for the front is not completly square, does it matter which way it gets installed.
#11
Hey Wile E. Thanks for the order.
Sorry for the delay. The bushing goes with the divot in the lower left and upper right as your sitting in the drivers seat.
Let me know how you make out.

Got it installed, fit and finish are excellent. Haven't got it on the road yet, been putting on new brakes and shocks and cleaning and painting the underneath. Can't wait to feel the difference.

Good luck and let me know if you need anything.

Make sure to get the right cross member for your transmission. I made the mistake in buying a used torque arm and relocation kit and the cross member was for a 4l60e. I have a t56.
