TA relocation crossmember adjustability question
TA relocation crossmember adjustability question I just ordered a BMR torque arm relocation crossmember for my Z28 (M6) and was wondering if anyone had any results from changing the mounting height of the front of the torque arm. I would think that technically there is only one proper pinion angle setting for a specific application and therefore, having an extra point of adjustability doesn't really make much sense if you have an adjustable torque arm. I know this isn't the main point of buying the part as relocating the mounting point off the tailshaft is why I bought it, but I was wondering if the extra adjustability was really a major benefit or just kind of there.
In case it matters, the related chassis/drivetrain/suspension parts on the car are adjustable torque arm, adjustable panhard bar, lower control arms and relocation brackets, driveshaft safety loop (all BMR), Moser 12-bolt, MN12 GTO trans, 3.5" aluminum driveshaft. I drive mostly on the street but hit up a few track rentals per year where I run 16" ET Streets and launch around 4500-5000 RPM (would launch higher if the tires held).

Jimmy is 100% correct. A good starting point for the crossmember is the fourth hole from the bottom. Put you lower control arms in the bottom hole. If the car hooks then unloads move the lca's up to the middle hole.
