So when I start to get to 4th gear around 2500 rpm at 70mph the entire car starts to vibrate. I feel it and see it in the stearing wheel, seats,etc. What could this be? Possibly need an alignment? Or could it be the drive shaft? The car is has an aftermarket torque arm, panhard bar, subframes welded in and the cam shaft exhaust etc are done giving me roughly 405hp at the stock rearend. Any help is greatly appreciated!

might be a driveshaft, or tires might need balancing

I had the same problem, except it was any gear between 70 and 85. I thought it was the driveshaft because I've had that problem on a couple of previous cars, but it went away when I put new tires on it.

tires balanced/aligned and balance the driveshaft.
