Installation Time: Afternoon

Much better than factory mounts.
After I lowered my GT with SR springs, I developed a popping/clunking noise in my driver side strut mount along with visible negative camber on both wheels. I attributed the sound to the factory rubber spring isolator and first purchased the Eibach camber adjustment bolts to address the alignment. While the bolts worked great in my driveway when I installed them myself, I had a hard time getting the alignment shops to touch them, even after I explained exactly what they were and how they worked. That's when I decided to go with camber plates, and J&M was certainly the right choice. The only thing I overlooked was the fact that these plates don't come with replacement rubber spring isolators; you have to reuse the worn and soft factory ones! (The only flaw in an otherwise perfect product.) If your factory spring isolators are ruined, you must buy the Ford Racing GT500 style mounts which DO include the spring isolators, only without the camber adjustment. If you've got the cash, buy both. Then you can put the spring isolator from the GT500 mounts on the J&M camber plates.
The install took a few hours, being as you must remove the struts from the vehicle. You should set aside a full day if you've never done this.
(If you're replacing the springs or struts and adding the camber plates at the same time, then you can get away with not using a spring compressor tool!)
The four studs are bigger and stronger than factory, even requiring a heavier torque spec. (35 ft-lbs). I was relieved to see that the studs are plenty long enough to fit my SR Strut Tower Brace with no problems while still offering full adjustability. These mounts are very high quality, much stronger than the factory mounts and look amazing. When you open the box, you will have a smile on your face and when you see your old mounts, that smile will get even bigger knowing you are replacing them with something so much better.
I have used these plates with both SR lowering springs and the Eibach lowering springs, both with successful camber adjustment. I would recommend skipping the camber bolts and buying these first, just be aware that the rubber spring isolators from the factory mounts must be re-used.
Overall: Excellent quality, perfect fit, reasonable price, sensible upgrade, but I wish it came with that spring isolator.
