Torque Thursts for a 67 camaro z/28

[Ron C.]

anyone here put a set of 15 inch torque thrusts on their 67 camaro? If so what part number or offset would I need?

Hi Ron

I have a '68 Z and have tried unsuccessfully to mount a couple of sets of TTII's on my car in the past. I was never sure just why as American Wheel specs say they were models that should have also been a correct fit for a '67 Corvette which apparently also has the same large J52 calipers that our '67 and '68 Z's have on them - but I had no luck fitting them..
From what I have seen in my attempts - its not so much the offset or backspacing of the wheels themselves, but more the actual hub where the spokes begin, that seems too large and/or thick and interferes with the calipers (original to my car)..
I would love to hear what success you have in finding some and what specs for any wheels you may end up with that actually do work.
Where I live I am very limited in opportunities to actually get to try many aftermarket wheels at all without having to actually buy and get them shipped here first - so obviously that limits me greatly in experimentation!

Thanks - Randy

My '67 RS/SS had TT's on it from the time it was about 3 months old. I know the original owner, but details have been long forgotten. I don't know which model number he used., and unfortunately no pics exist that I know of. They were 6X15's, that much I do know. It has drum brakes so clearance would not have been an issue.

i was just watching a 67 convertible on ebay that had 15x8 torq thrusts on all four.  i love that look and am thinking about them as well.  i guess i wont order any just yet!  ill also need to make sure theyll work when i put discs up front.  my local les scwhab has a pair in stock... i may be able to try them on.  good luck with your venture

[lykaneagle]

correction....they were 15x7 on all four

Ron,
  With factory disc brakes you may ned to use 1/4" spacers with extended tip lug nuts. look in the vinyl top thread to see pictures of cars with TT wheels The blue car is pictured with both 15 x 7 (parking lot, all four) and 15 x 8.5  (car show, 15 x 5 front) wheels in the rear. hope it helps.

My 67 L78 w/original tt but there is no identification on the wheel anywhere other than the
center caps has American Racing on it not A R Equipment. Also the fronts are 14 x 6 and rear are 15 x7.
The inside of the front measure 12 1/2 inches  and clears the original disc brakes. Back spacing is 3 1/4.

1/2" offset.

These spacers were used a lot back when the '67 Camaro first came out, with a lot of different Mag Wheel manufacturers ( including CRAGARS I remember)   My brother had a '67 Camaro SS with Disc Brakes and reversed CRAGARS, and I remember that was the solution.  Back-spacing was not the issue, it was the contour of the back of the spokes/hub.

Thanks everyone who responded,I didnt know this was such a issue and allthough I do like the look of the TT wheels I will not put a adaptor behind the wheels.I have had that experince before and it was nothing but trouble.If anyone knows more about this please post.I am not giveing up yet LOL.

I have run the original '60s era Torq-thrust "D" on my Camaros and did not ever use a spacer. The inside edge of the spokes
nearest the bolt circle made very slight contact with the stock calipers but I ran them like that for years and never had a problem.
You could likely grind the area of the spokes that was needed for extra clearance but I never did. The 15x6" versions work best
up front. 15x7" wheels will rub on a '67-68 unless you are using a pretty skinny tire.

Ron C.>>>,
  We're not talking about adaptors, as stated 1/4 in. spacers.  There is a difference.

Ron,
 The good spacers are machined concentric, Five percise stud holes and one large hole for the hub. Stay away from the mega-fit anything cheapos.
  The 67, 68 4 piston calipers have a couple of little tits (cast ports) that can be ground for clearance if you don't want to use spacers, I could not ruin original patrs even if I needed to.

Jon,
 How did you run those for years without damaging both the wheels and the calipers?
