ajustable rear lower controll arms?
so i made some ajustable lower controll arms for the rear of my car. I came up with the idea because when i had lowered my car i started geting a vibration when i would get to about 65 mph.i checked my pinion angle and it was slightly off, about 4 degrees so i wanted to try this out. i just intalled them today so well see how they work . heres some pics. what do you guys think

yeah made it myself. I used the stock arms and some grade 8 bolts and nuts I machined to fit.really only cost me about 15 dollars total and some time.
heres some pics of the machining i did.

So I got a chance to work on the pinion angle and I was off like 3 degrees. So I adjusted the arms then drove it around and now its all good. So far I'm happy with the results after some spirited driving.

Im glad to see this come up. Iv recently lowered my car drastically when I some skinnier tires, and for the past few weeks i really want to get the adjustable rear control arms from re-speed but i dont know how to measure the rear pinion angle and or get better angle. I have all four corners on re-speed coil-overs and im getting to the last threads 
Any advice will be greatly appreciated

step 1: lift the car up with all the suspension compressed with jack stands.
step 2: remove the drive shaft (make sure you put a drip pan for the tanny fluid).
step 3: place angle finder on the face of the tail on the trans and take your reading (mine was -2.5).
step 4: place angle finder on the face of the pinion (where the driveshaft bolts up to) take a reading (mine was -1.5)
step 5: i adgusted my arms to give me +2.0 degrees
step 6: try it out.

you could use the stock arms,a threaded tubes, and 5/8-16 right hand and left hand thread bolts. not sure where to get left hand thread bolts and jam nuts tho.
heres a link to the threaded tube i thought of using
