I have a 64 L76 with a set of NOS wheels. I'd like to get some torq thrust D's for everyday driving (not often) and would like to know the workable size/offset. I'd think 7" or 8" wide, I'd like to fill the wheel wells. The c2 is all stock except for a set of chambered utc pipes. Ssuggestions? Thanks

Re: torq thrust D's size
With tire near OE diameter, the seven will probably not work and the eight is out of the question. It comes down to wheel offset and specfic tire size.
If you want to use a "short" tire, sevens might work, but it could look rather odd.

Re: torq thrust D's size
Jack, I have what I guess you'd call custom made torq thrust D's, 7 inch with 215/70 BW radials on my 66. No problems with hitting the fenders, at least not yet and I've driven it over 2000 miles. When I first started looking at using this type of wheel I discovered that ARM does not currently make a TTD wheel that will fit the 65-67. If you want to use one of their wheels a spacer is needed to get the correct clearance for the caliper if you have a 65-67. Not sure about the drum brake cars. Apparently they can't make the same design wheel they made in the 60's??? Maybe it's a case of economics.
The wheels I have were made by someone in CA who apparently buys the components from ARM and puts them together with the correct offset/backspacing. I purchased them from a third party so offhand I don't know the name of manufacturer. Email me if you want to pursue this further.Comment

Re: torq thrust D's size
Jack,
I have the 6" Torq-Thrusts made by PS Engineering in Torrance, California. They have zero offset and like the original American Racing T-Q D's, they clear the calipers. They're mounted with 215-65-15 Eagle GA's with no clearance problems. Good luck. Jim Weeks Member #2978

I also run the redlines and rally wheels occasionally to maintain NCRS political correctness. Kind regards, Jim Weeks Member #2978

Re: torq thrust D's size
Thanks. Nice pic. If you read the posts, I'm still concerned about the 7" so maybe stay with the 6".Comment

Re: torq thrust D's size
One other tidbit. Negative camber provides more clearance margin with the fender lips. Changing camber one degree in the negative direction will move the top of a 27" OD tire inboard by about a quarter inch.
For best handling I recommend negative one degree camber, front and rear, with urethane bushings in the front anti-roll bar links.

Re: torq thrust D's size
I run "17x7" inch Torque Thrusts on my 67. No problems with fender clearance or tire rub anywhere.
Tire size is 245/45-17.
Looks great and handles MUCH better.

Do you have a web address or phone number for them? Could you supply it?

Re: torq thrust D's size
Duke,
Reading this thread makes me a little nervous re a winter acquisition. I thought that I had done my homework but....The pic shows AR Torq Thrust IIs provided by the company with a 6" width and 3 3/8" backspacing (supposedly custom made for a C2). I am not sure of the offset but I believe it is +1/8". My tire of choice to accompany these is the Pirelli P4000 Supertouring 215-70ZR/15. I cannot try these on my 1967 until April (storage insurance reasons). Am I in for a rude surprise?Comment

Re: torq thrust D's size
I don't think you're going to have a problem, but as I stated previously camber can have a big effect. "Touring" camber settings are zero in front and minus one-half in the rear. "Performance" camber settings are negative one degree front and rear. Either way I recommned hard urethane bushings on the front anti-roll bar links.
How about measuring the offset? Place the wheel outside face down on a flat surface and place a straight edge across the the inside flanges.
Measure from the straight edge to the surface and call this dimension "A", which is the overall width of the wheel including the flanges.
Now measure from the straight edge to the wheel mounting plane - "B"
Offset = B - A/2

Re: torq thrust D's size
Duke,
(A) is 6 7/8" and (B) is 3 3/8". That gives an offset of -0.062 or virtually 0. The current wheel/tire combo (that I will store) is 6" ralleys with Dunlop Axiom 215-70R/15s: same size as the Pirellis. I have no problem with them so I was optimistic that the new combo would be just fine. Any further comments would be very much appreciated. A camber adjustment to make tires fit seems a little on the risky side!Comment

Re: torq thrust D's size
The 6" Rally wheel offset is +0.060, so the TTs will push the edge of the tire outboard by 1/8". It should not be a problem if your camber is reasonable.
