Trailing Arms..........Width
What's the offset difference between Standard trailing arms and Offset Trailing arms?
When changing to Offset arms, what else needs to be changed?
What's the new backspacing requirement and the widest wheel I can run?
Questions, questions, questions......

The Typical offset is 2”. You should be able to run a 2” wider rim and tire than what you have now. You will need to get new rims with 2” of offset or your wheels will stick out from the side of the car. I have not installed my T-arms yet but hope they will be here soon. I got mine from VBP; Allen was great to work with. I also talked to Tire Rack, the person I talked to was not very good at his job and I don’t know if I want to work with them after that experience. I was able to find out that I should be able to fit a 285/17 tire with the offset t-arm on my 68. Hope this helps some.

VBP is likely responding to this to clear this up for you.... 
From what i've heard the offset T-arms don't change the position of the rim's mounting surface at all. They are offset so that the tire doesn't hit the arm, basically it's 'double offset' allowing the use of wider rims/tires.

That's right. You don't NEED to change anything because the mounting area is in the exact same spot - so you can just put your stock wheels back on if you want. However, since the arms are "bent" in the middle, you can put a wider wheel and tire combination. As a bonus, they seem to be made much tougher...
