[TR] Rear End Camber on TR6

[DAVID MASSEY]

VTR or Buckeye Triumphs (can't remember which) has a chart showing the various configurations of the brackets and how they affect rear geometry.

 I forget where I got it but I archived it:
TR6 rear camber:outer bracket - inner bracket - relative camber angle(degrees) 3D                 - 3U                 - 0.00 3D                 - 2D                 - 0.98 (waspreviously published in error as 3D 2U) 2U                 - 3U                 - 1.50 3D                 - 1U                 - 2.11 1D                 - 3U                 - 2.42 2U                 - 2D                 - 2.49 1D                 - 2D                 - 3.40 3D                 - 1D                 - 3.49 2U                 - 1U                 - 3.61 1U                 - 3U                 - 3.80 3D                 - 2U                 - 4.40 1D                 - 1U                 - 4.53 1U                 - 2D                 - 4.78 2D                 - 3U                 - 4.93 2U                 - 1D                 - 4.99 3U                 - 3U                 - 5.91 2D                 - 2D                 - 5.91 1U                 - 1U                 - 5.91 1D                 - 1D                 - 5.91 2U                 - 2U                 - 5.91 3D                 - 3D                 - 5.91 1D                 - 2U                 - 6.83 3U                 - 2D                 - 6.89 2D                 - 1U                 - 7.04 1U                 - 1D                 - 7.29 2U                 - 3D                 - 7.42 3U                 - 1U                 - 8.02 1U                 - 2U                 - 8.21 1D                 - 3D                 - 8.33 2D                 - 1D                 - 8.42 2D                 - 2U                 - 9.33 3U                 - 1D                 - 9.40 1U                 - 3D                 - 9.71 3U                 - 2U                 - 10.32 2D                 - 3D                 - 10.84 3U                 - 3D                 - 11.82
So, as you can see you can get quite a range of adjustment by swapping and flipping the brackets.
But, I'm with you, the adjustable brackets are the way to go.  The only reason not to use them is the cost, and they aren't that expensive.

No problems with the adjustable brackets after 5-6 years.  I have poly bushings for the trailing arms though.
VTR or Buckeye Triumphs (can't remember which) has a chart showing the various configurations of the brackets and how they affect rear geometry.
However, the rubber bushings are cheap, $2-4 depending on the source, I would swap out the bushings and put the adjustables back on rather than messing with flipping and swapping out stock brackets.

Hi All,
        I’m now trying to adjust the camber on the rear wheels of my TR6.  After changing out he bushings I’m finding that the drivers side is within spec, but the passenger side is 3/1/2 degrees negative reinstalled the original trailing arm brackets in the original configuration. I had installed adjustable trailing arm brackets about 10 years ago, but when I inspected them this spring the bushings were really destroyed. I’m not sure that the damage was due to crappy bushings or that the adjustable brackets were causing a problem. Although the stock brackets are simple, figuring out how to configure the brackets to get the camber right is much more difficult than adjusting the adjustable brackets. Has anyone who has installed adjustable trailing arm brackets had a similar experience?
        Best,
