I installed a T56 Magnum in my 1999 camaro. When I get over 65mph I have a very bad vibration. I have had my driveshaft rebalanced and been under the car and checked everything. All of my suspension is Spoon performance and have a dayna rear 4.10 gears and a spec super twin clutch. I have checked my front yoke when in the trans seams to have a little play is this ok?

Did you check the basics, like tire balance? I suppose it could happen, but I have never heard/seen a trans cause a speed related vibration. Does it happen at that speed only or is it rpm dependent? Does it matter if the clutch pedal is pressed or not, which gear you are in?

Sounds like a possible driveline angle issue.

My drive angle is set @ -1degree,my trans points down 3 degree and I have my pinion up 2 degree.
I have two different sets of tires that I use on the back ( drag radials and street tires ) and it does it with both.
It is a speed problem cause I could press the clutch in and it is still there.

Your pinion shouldn't be pointing positive.

The more I read about pinion angle the less I know about pinion angle

I would set it about -2 to -4 and give it a shot.
