Depending on the tolerances and condition of your subframe you should be able to get a bunch more caster with that many shims.

Oops...I meant camber.

What slugs you got in the upper arms?

Center hole slugs.

Place a two foot long carpenters level up against the tire. the part of the tire that contacts the level will be around 20" apart. Using those points, the tire will have a gap at the top of around 1/2" at 1.5 degees neg camber.

Thanks David. That's a great idea for a quick check. I was getting a little worried because my shims were stacking up over half an inch.

Wow my head is spinning after reading through this whole thread again. I just measured my 69 Camaro last night and ended up ordering 18x9's with 6.125" backspacing. I found on my car that a 6" BS would be ideal but erred on the side of caution and went with another 1/8" of BS figuring I can run a shim. (Edit: I am running the std C6 corvette brakes with the Kore3 hubs which reduces the front track width .24" per side.). I plan on running my car at the same ride height as the Blue Ridetech Camaro mentioned earlier in this thread, 23 3/8" from ground to wheel molding. Even with that, the tire looks like it will get into the outer fender with anything greater than 2" of compression from ride height at full lock. (Edit: this was tested at -1 degree of camber)

It looks like I will have to weld washers on the lower control arms to limit the turning radius just a hair, but I don't fore see it affecting drivability that much. Otherwise the tires will lightly hit the frame and sway bar.

Has anyone with a 69 Camaro and the Ridetech Truturn have any real world feedback on their tire/wheel combination?

Ridetech TruTurn on my '69
 

I have been running the Ridetech TruTurn on my '69 for 1 1/2 years. I went with a 18"x9" wheel with 5 3/4" B.S. (275 mm tire) but wish I had gone with 6" for a little more clearance. I am at 23 3/16" from ground to lip of wheel opening. My alignment settings are -0.8 Camber and +5 1/2 Caster. I drilled & tapped the lower control arms and added a bolt to limit turning radius and prevent rubbing on the sway bar and frame. On occasion the tire rubs the top lip of the fender at full lock if also navigating over rough terrain (parking in a field). I just touch up the paint under there a couple times a year.

I have a 69 nova with 383 stroker , hooker super comp headers . I want to
Get the true then set up to guy a 275 under my car .... Is there going to be any issues due to my oil Pan or headers ? And if you get tru turn do you have to you the muscle bar sway bar or can i still use my dse sway bar

What oil pan are you currently using?

The Ridetech front sway bar will probably add additional turning radius over the DSE bar.
