The past month we have been running on a carpet track with low to medium traction, and the surface temperature has been low (45 to 55 degrees). Using the 7A rear camber link with a silver ball stud and 1mm roll center spacing really helped hook up the rear end compared to Keven's Halloween setup.
Once it warms up, if your track develops a groove quickly, or at bigger races, 7A may not allow enough rotation, but in the right conditions, it's a great option.
Note that this is closer to the manual setup. Several folks were experiencing over-rotation with the short rear camber link, and 7A will help. We also have been running a little more droop and rear toe-in and unhooked the rear swaybar.
Cheers!
