Currently I have an Inland Empire T6061 3" aluminum driveshaft, which I originally installed years ago in my 1991 Formula to eliminate a bad vibration I had with 4.10 gears and my stock steel driveshaft (unknown if it was out of balance or what, I just wanted the benefits of the higher critical speed and lighter weight of the new shaft).

The car is a stick car, and will wear slicks at the track, and could see up to 500RWTQ and clutch dumps. So, now I have a Moser 12-bolt and the stock driveshaft length has the yoke bottoming out in the back of my T56. I am going to need to have this shaft resized and for the cost of that I am just considering selling it and buying a new 3" steel shaft in the correct length.

Or what about having the stock 2.5" steel shaft resized and balanced? Slightly more cost effective, and I have seen it done, but either way I don't want something that is going to vibrate like crazy or rip apart on me. I would like to stay away from spending $500+ on a driveshaft if possible, so nothing too exotic.

So what would TGO do?

 

Damn, I wish I could answer you, but i have a stock 1LE shaft, and it has been really good for me......Alot less vibration than the steel one......

 

I use a 3" steel driveshaft. Custom made from standard 3" x .083" tube and I had 1350 yokes installed on it although you could just as easily use a smaller u-joint to cut costs and strength but I wouldn't recommend it.

You spend money to build a lot of power then want to save money on getting it to the ground. Do it properly the first time and you won't have any problems.
