Im liking the BMR trak pak right now, and am 99% sure getting it, but a few questions. Does it make a big difference over a good AM torque arm? Car should be tens no problem by the way with squeeze.

Also is there clearance for duals?

An aftermarket TA is going to be heavier and less flex. Depending on which one you get Duals with an X might not be possible. I have a Spohn unit and it will not allow an X. I run an automagic, so i probably not run a aftermarket TA...I have a buddy with the Jegster or LGM TA and he has an X.
