You need an adjustable PHB. The non-adjustable ones are made for stock ride height.

Wow, yeah sorry I totally misread your post.

I don't believe you would need an adjustable tq arm when being lowered but I'm not sure.

why do you feel that you need a torque arm? are you just afraid of breaking yours, or are you having wheel hop/traction issues?

i have a non adjustable edelbrock torque arm(got it extremely cheap) which i believe is the same setting as stock, and it helped eliminate the rest of the wheel hop on my lowered car. adjustable isn't absolutely required, but it's probably a tad better.

honestly, i would get the adjustable one. UMI ships them at stock settings, so it would be just like a non-adjustable one at that point, but if you do ever need the adjustment, you have that option down the road, too.

if you go non-adjustable, and for some reason you need to adjust it later, you'll just end up having to buy an entirely new torque arm, which would be much more costly than if you had just spent the money on the adjustable one in the first place.

I have the same question as the OP too.

WHY would you ever need an Ajd. TQ Arm? What mods and/or activities necessitate one?

^^^ lowering a car will throw off the pinion angle slightly. an adjustable torque arm will allow you to correct it.

My understanding is you would need adj T/A for drag racing so you can fine tune your suspension geometry therefore better 60' and ET.

aka adjusting/correcting the pinion angle

Right, therefore only if your car is dedicated drag only car, I'd buy something non-adj or just use the stock one.

yeah, I don't drag really so I saw no need for a $400 adjustable one. I like turning, and torque arms don't help that(well, there is one but it's $700+), so I just picked up a cheap one used. It does it's job, no wheel hop leaving around corners from a stop. I'm happy.

you need an adjustable one for a lowered car. You need to correct the pinion angle. lots of bad advice in this thread. Pinion angle is important, and it isnt just for drag racing purposes. Having bad drivetrain geometry will effect the cars handling and performance.

How do you know where to set an Adj. TQ Arm? Do you need tools, or is it an "eyeball" type of thing? I'm lowered with Strano springs (1.2"), so what kind of problems is that causing with the pinion angle and how much improvement are we talking about with an Adj. TQ Arm?

you don't "NEED" an adjustable torque arm in my opinion. is it a good idea? yes, but it's not absolutely required. i 100% dead hook on drag radials with a non adjustable torque arm, no wheel hop or tire spin at all. a 1.2" drop isn't going to put you at the point where the pinion angle is so far off that the U joints are going to bind.

yes it would be ideal, but if you don't have the money and just want something stronger than stock just to avoid snapping it and possibly damaging other things, non adjustable is fine. that's why i asked why the OP thought he needed one.

i would get adj.
just make sure you set your pinion angle correctly.
Spohn torque arms look really good.

Badazz 97 T/A is right. Its not about performance gains its about retaining correct geometry.
