2" offset trailing arms
I think you're not rubbing because of a properly backspaces rims. It will totally depend on that.
I'm planning on installing 2" offset trailing arms too on my 73, What do you guys think about those ? Which, I think, will enable me to use 7" backspaced 10" wide rims.
AM I RIGHT ?

18x10 with 7" backspace will put the wheel / tire into the frame. backspacing is important for clearance, fitment and for most, to keep the wide wheels tucked in the wells. i'm running the same combo as deuce02 but with double offset arms and 5.5" wheel backspacing

I went with Van Steel double off set t/a's (REALLY NICE STUFF) and and a shortend Vette brakes rear spring on 17x9.5 t/t's with 5.5" back spacing, they look great with 275/17 tires, I think I could go with 295's but need to trash these new tires first 
, I don't think I could go with anymore back spacing with out cutting into the side if body, IMHO

Shoot I'm running 5" of backspacing and 275-40-17s on stock trailing arms and no rubbing. However my parking brake cable bracket is relocated to the top of the trailing arms and I'm using 1/4" spacers in the back because the wheels hit the calipers without em.
Unless you're in to drag racing, I don't see any need for more than 275-40-17s. Those that win at autocross don't usually use much wider than that on vettes. Z06s usually use like 315s, but they have 405 - 505hp... So unless you've got that much power, what's the point?

Deuce 02, Thanks for the post and the very nice pic.
But I think those tires stick out a bit don’t they? I can’t tell from the pic! How much is your backspace?
Wnjlt1, Very nice car and thanks a lot for the tip, but what do you mean by “Double offset arms”? Are those the 2” offset ones or is it something else ? Are your rims 17 or 18” ?
Kalway, to be honest with you, it’s the looks I’m after
not traction. I love the look of humongous rear tires all tucked in. Would love to fit 315’s but I don’t think it’s possible

hemorrhage22,
the offset trailing arms and the double offset trailing arms are essentially the same with the exception that the double offset arm's spring bolt and swaybar hole locations are 1" inwards allowing the spring bolt to be vertically aligned when used with a shorter rear spring. Yes on the 2" ones (van steel) and running the 17 front / 18 rear wheel combo.

Not much more than 275 will fit in the wheel tub. I have 275 40 18s and they are just about maxed out. Running an 18X10 with a 5.5 backspace on stock trailing arms.
Yes I do have around 500 HP and it just smokes the 275s with ease at the track and autoX

With 16's you can't go as wide on the rim size as others. 9" maybe 9.5" wide. You can probably get away with running 285.50.16 but you can't run a rear bar. The problem with smaller diameter rims is that the tires have fat side walls so your sectional width on the tire is greater than that of a taller rim and tire combo. Thats why the guys above are running 10" wide rims.
Double offsets just move spring bolt hole location inward 1". The offset of the arm is the exact same as a standard offset t-arm. A shortened spring is required for the double offsets.

I've got 18x9.5 wheels and 275/40-18 tires with standard trailing arms. I modified my rear sway bar. To see how, click on my picturetrail link below. I now have room for the 18x10.5 wheels and 295/35-18 Z06 wheels and tires now. I just haven't found affordable tires yet. Anyone got 295/35-18 tires for sale?

You carefully cut the old one off and reweld it to the top.
Top flight did it for me, though. Charged me $120. Well a welding torch alone woulda cost... a lot more than that.

Double Vs. 2" ... Again
Sorry guys for asking so many question abou those trailing arms, but i really need to get this thing right before i order mine. Please bare with me !
So, What's the advantage of going with a double offset arms and a shortened spring intead of a regular length one with 2" arms ?
I know the wholes for the spring will be vertically aligned, but what good is that gonna do me ?
Trully Appreciate it

I run regular offset with the stock spring and bolts and it tucks in the wheel pretty good but if I lowered the car using longer spring bolt it would not work,the bolt would hit the wheel,and thats where the double offsets work, and I run 18x10 with 295 35 18

@ this point, everyone has been very helpful with offering their advise, experience, combo's, etc.... that's what makes this a great forum.
to answer some of your questions, how about some information on what your plans are? wheel type, tires, sizes, spring setup, what's important to you, wheels not sticking out, retaining swaybar, car stance...? for others and myself, this info would definately help.

First, I’d like to apologies to Pionty1, but I’m sure you are benefiting from my questions and concerns .
My plans are to install 10x 18 backs and 17x 8 fronts. I have not chosen a wheel yet, first I want to make sure my car will fit big ones first. But I really like this wheel I found on the net (check pic) I’m currently searching it to see what type it is. If anyone knows, please help out !!
http://www.cardomain.com/ride/2570702
Van Steel has offered me a good combination to begin with. 360 # rear leaf spring with double offset trailing arms. Think I will go with that set up, what do you guys think?
My priority is to fit the widest tires in the back without sticking out.
Not sure what you mean by car stance !!
