I need an 18X8'' rear wheel to fit my 67 that has more than 5.00"s of back spacing any recommendations?

 

stock frame, stock T/A or stock 1/4's?

 

possible with offset trailing arms.

 

With 18" wheels offset trailing arms offer no advantage. The frame becomes the limiting factor. That's also verified by VanSteel. That being said there's no guarantee you're going to get an 8" wheel in there anyway. Besides that you may squeeze it in one one side and not the other. Your best shot at seeing if you can get the 8" wheel to work is to use a tool like this to experiment.

They cost about $85.00 plus shipping. IMCO money well spent. Custom wheels are expensive. Might as well try to get it right the 1st time.
If you're going to go with a 2 piece wheel you can ask the company to send you the wheel before it's welded together. You bolt on the center section and position the hoop in the best possible backspace. Mark the hope and send it back to be welded in place. That just about assures the backspace is correct for your car.
Good luk going forward.

 

not True.

Thanks for trying to correct me but your wrong just as you were the last time we got in this discussion.
Besides are you speaking from actual experience or just trying to contradict me?
Do I have to go back and pull up the post that has the quote from VanSteel?
Or can you finally take my word for it as it's from actual experience.

 

Ya, go ahead and pull up the post and quote from Vansteel.

At least I provided proof that's contrary to what you're saying.

Where's your proof?

Now can we get back to furthering the thread?

 

It's posted.
Now can we get back to being helpful instead of contradictory.
Thank you.

 

That's not proof; there's hearsay.

I want DOCUMENTED PROOF that with 18" wheels that offset trailing arms will not have ANY WHATSOEVER benefit over stock arms.

Otherwise, why would anyone buy those offset arms?

All the literature that Vansteel put out (that I referenced) makes NO MENTION that 18" wheels will negate the benefits of offset trailing arms.

 

Is there any mention of 18" wheels here?

Offsets vs Factory Trailing Arms

65-82 Corvette rear trailing arms and how offset t-arms work.

Our standard offsets and coilover t-arms offer 2″ of additional backspacing for aftermarket wheels. By moving the parking brake bracket to the top of the arm we gain one Inch, then we offset the entire t-arm between the pivot mount and the bearing mounting surface another inch for max wheel and tire clearance of an additional 2″ over factory trailing arms. The bearing assembly, camber/strut rod, and half shafts remain in the factory location.

These arms are also stronger than factory arm and can’t hold water/moisture like factory arms where they are prone to rusting from the inside-out. Our bearing pivot mount reduces binding in the system which allows for better ride on the street and better handling for the track. Finally, the bearing is held in by a snap ring so it is easily replaced if it wears out. For max wheel and tire clearance, we suggest converting to coilovers which eliminates any leaf spring clearance issues. With our standard offset trailing arms, you may need a shortened composite spring to clear your new wheel and tire package. See our wheel and tire chart for C2 and C3 Vette size options.
Please point it out to me.
Your can call the quote hearsay and continue to insult me if it makes you feel better.
As I previously stated I'm speaking from experience.
You're calling me a liar. I'm here to share and learn.
You can disagree without insulting me,
That's up to you.

 

I have had 18 x 8 Boyd Cottington Junkyard Dogs with 4.5 BS on my 67 for a few years. Stock trailing arms with the e-brake NOT moved. Only in the rear, 18 x 7 in front. I put Van Steel offset arms in it last fall and it could have gone to much wider tires with more back spacing. I am waiting on parts, but I'm putting the Ridetech Track 1 with C7 hubs in the rear and the best would be 5.5 inches backspacing. I know a guy with 18 x10 5.5 backspacing on his 65. I found that Ridler and American Racing have stock 18 x 9.5 with 6mm offset which is probably too much. 5.5 is the limit from what I've found as it will hit the frame. With the Van Steel I could easily go another 1 inch of Backspacing. The Ridetechs also allow that. My research has told me that 245 will fit, no problem. 275 is possible but close with 5 or a bit more backspacing. I'll know a lot more once I get the Ridetech Track 1 in.
