Installed J&M LCAs... excellent!
I got those $85 J&M LCAs on sale at American Muscle a while ago, and finally got around to installing them. They worked like a champ - wheel hop all gone. Here's some pictures, in no particular order.
Stock arm vs. J&M arm.
Driver side arm installed.
Pass. side arm through the reinstalled wheel.
Shot from under the car of the pass. side.
Driver side, past some cheap duralast jack stands (yes, I jacked via the pumpkin - I know, I'm a horrible person)
A final note - they install way, way easier if you grease up the sides of the bushings just before installation. I have a tub of Valvoline synthetic wheel bearing grease I used, and they just slide right on up in there.
There is no perceptible NVH increase, and I burned all the way through 1st and all the way through 2nd, and there was nary a bunny hop in sight. Truly wonderful.

Are these the LCAs? If so, it sounds like you got an awesome deal.

Sorry if your pics answer some of my questions. I'm on my work computer which blocks the server that the pics are coming from.

One final note: Wear gloves while assembling the bushings - you know, those latex examination gloves. The supplied assembly grease is incredibly sticky. Nasty stuff.

I found them unacceptably noisy......Something Mustang guys seem to put up with.
I don't do burn outs so wheel hop is not an issue for me. I'm not the only one to try these and take them off.
YMMV. Sold on Ebay last week...

Agreed - each person's idea of what's acceptable in terms of increase in NVH is subjective. Poly bushings will undoubtedly increase NVH. Rubber bushings like the Roush LCAs probably fair better in terms of NVH but there is a tradeoff with max performance.

Yup....Looking at the parts, notice the large metal Bush center on the stock parts. These have ribs on them, so when torqued to spec, the arm and center bush isn't moving back and forth against the bolt. On the poly bushed LCA's you don't have this precise clamping of the bush so the arm and metal bushing insert moves back and forth on the bolt. This induces some klunking that no amount of tightening can remove. While the bolt to bushing clearances are good, they're not good enough to prevent some slight movement (and resulting mechanical noise)
