I have a 94-95 mustang gt. Im looking to get rear control arms but cant decide on brand. Wasnt sure which ones to get or if they needed to be adjustable. I have pair of 50/50 lakewood rear shocks and set of moroso trick track springs. Rear gears are 373. Car isnt daily driven but isnt scared to see both track and street. Whats yalls opinions. Also how much of a 60' will control arms help?

Pretty much any tubular setup with some poly bushings will be a big upgrade. Adjustable uppers would be a plus as they allow you to change pinion angle, but not really necessary unless you're leaving really hard on some slicks IMO. Old school southside lift bars work really well, but tend to creak and pop more from my experience.

What are your current 60' times?
What tires?
Combo and launch rpm?

My best pass was 14.0 at 98.xx mph. Sounds silly but not bad when it ran 15.7 when I bought the car. That was with a 245 tire, 308 rear gears blown shocks, and worn out limited slip so it was a one wheel peel. I just recently rebuilt the limited slip. I have ford racing 373 rear gears, lakewood 50/50 rear shocks, moroso trick track springs awaiting install. I was just waiting to get control arms as well. My best 60' was 2.3. I also have a pair of weld prostars slicks and skinnies with a 28x15 slick. The motor isnt much yet just working on suspension then focus on getting it to the rear.

You need a LOT of gear to turn a 28inch tall tire at your power levels (unless your on the bottle as well).

A good tubular lower with good poly bushing and nice double adjustable uppers as stated and it will hook on a tire. Try a 26 inch tall slick with those 3.73's and it will wake up.

I have a nitrous kit with 150 shot. I sprayed it once had a nitrous backfire and took it off. I need someone with experience to either explain the correct way to set it up and use it or help me. Do you have a preference on control arms as far as brand? With the double adjustable uppers is there a precise pinion angle to run or what?

For poly bushings set the pinion angle @ -2*.

26X10 slick would be a better choice to keep the rpm in a more useable range.

Just gotta figure out what the car "wants" to make it work.

Thats what I heard. Just what brand of control arms?

Most lowers are going to be equal (we use cheap ass tubular, I think summitt or lmr brand) then have a better upper that is adjustable (used to use the same non adj uppers as before, the adjustable ones took from 1.69 to 1.51 60 foot times)

Squeak what pinion angle do you run?

Also on the uppers do I need to find ones with solid bushings or poly bushings. Im having a hard time locating a set with non adjustable lowers and double adjusting uppers with the rubber bushings

So with no changes except to a adjustable upper your 60ft time dropped almost .2?

2.3LX you will probably have to purchase them separate.
I don't think they sell them as a set like that.

A new tire as well but even when the old tires were "fresh" we never cut better than high 1.6's. It should be noted that the upper bushings on the non adj tubular ones were not the best it appeared. I'm sure that helped. I can say since we added the uppers and went with the -2 pinion angle the car has been way more predictable (it used to UNLOAD the ass end bad after you launched) and it now yanks the wheels on each pass.

We bought ours separate.

Also should note the car I'm references has full coil overs and tubular front suspension as well. A 1.51 is a good time for this set up. (pi swapped, small cam 125 shot 98)

For 2.3 anything in low 1.6's would be a great goal to shoot for.
