If truth be known he as humped his rear geometry bad! I would recommend that he reinstall the factory components with your shaft and start over, one mod at a time checking his pinion Angle after each alteration.

We can see how changing control arms could possibly change the geometry if they aren't made exactly the same length, especially if you install an adjustable upper control arm. I doubt that coming out of the box an adjustable upper control is already set at exactly the same length as the OEM one since you wouldn't be buying one in the first place if you weren't planning on adjusting it. It doesn't make any since why we have sold plenty of our driveshafts to customers who are lowered and haven't experienced any vibrations without changing angles, we know Mustang owners like Taco Bill who have Coast and others with Spyder shafts are lowered and vibration free who didn't have to adjust pinion angle. If lowering causes a need to adjust pinion angle to rid vibration shouldn't it cause vibration consistently

As far as pinion angle, when I installed the 3.5" shaft my trans flange was at 99 and the rear flange with adaptor bolted on was at -1, so I guess this would be a 2 degree difference- whether or not its considered + or - I couldn't say LOL.

What I do know is that after having the shaft for a couple of months and now putting around 1000 miles on the car, I have a "vibration" that I believe is more harmonic- you can feel it and hear it a bit- at around 4000rpm. I thought it was only at speeds around 80+ but actually after driving it, you can tell it's there in most gears at any mph as long as your at 4000+rpm, however it just "feels" more pronounced at higher mph for some reason. I think I notice it more at the higher mph because 1st, 2nd, and 3rd gear go by so quick in my car, that once you get in the 4000rpm range you're shifting very quickly after that because it rockets to redline. In 4th gear at 4000+ rpm, you're approaching 100mph and I typically don't sustain that kind of speed.

With me (~200lbs), full audio system including a subwoofer box that I would guess weighs around 75lbs, and a 1/4 tank of gas the car weighs 3880 lbs. This is also with my 18" heavy wheels/tires.

Also today I got a discount code on modfords for M&H Tires..... anyone guess what I'll be doing in about 2 weeks?

But the way this economy is headed all of the manufacturers of new products seem to be in a wait and see attitude about releasing new projects to be tooled up. This past week we had to reduce some guys hours to 32hrs. And these guys are used to working 50-60 hrs week. And a program I have been working on with a stamper in Connerville Ind. since early January fell thru. The project ended up going overseas to be tooled. Just a bummer of a week.

When the quality doesn't meet our expectations we are forced to seek certain parts from other vendors. This always ends up cutting into our profit margin because the quality parts cost us more. We fear this trend is going to get worse. Greedy corporate america is sticking it to the average Joe. Not only are they paying lower wages over there, they also don't have to worry about pollution controls the way they do here. Have you seen some of the videos of the smog in China? It is so thick you can hardly see through it. Maybe our only chance is they will eventually become so sick from the pollution they are generating from the manufacturing that is robbing our jobs that they won't be able to work anymore.

He took 1000 pictures while there and everyone of them looked like there was a big fog. And he was extremely impressed with the shops he saw. All of the machinery was brand new and the best of everything. He came back and said he understands with the equipment they had and the wages they paid why they are kicking our asses. We have never built a tool of there mainly because they want to do it all or nothing for the most part.
