i plan on getting an adjustable torque arm and am wondering if i'll need to also get adjustable lower trailing arms. does anybody got some good info? thanks. dave

 

It depends on your need for adjustability. If I remember correctly the adjustable torque arm will alow you to change the pinion angle, and adjustable lower control arms would allow you to change the thrust angle (but dont quote me on it, might have em mixed up). One thing I know for sure, if your car is stock height or mildly lowered then chances are you wont need any adjustable parts, and even if you did get them, you might not even notice a difference. Of course this is a blanket statement and everyone has their own opinions, but thats the way I see it.

 

i have lowered my car and was going to get the spohn tq arm for the tremec. and it's adjustable. it'll adjust the pinion angle, correct. but so will the control arms. so thinking you'd have to have both adjustable other wise they'd be working against each other. i don't know, hence the question. thanks

 

The LCA's don't affect pinion angle. The torque arm is in sole control of that particular adjustment. The LCA's control both the thrust angle, and the front-rear position of the axle (to center the tire in the wheelwell.)
