[DeTomaso] Wheel alignment, loaded or unloaded?

[Thomas Törnblom]

Dang, you’re right.

Correct values:
Camber (negative) 16’ - 30’, 2 - 4 mm
Toe in: 16’ - 30’, 2 - 4 mm

Thanks Mike!

If you are to the cords on the inside of the tire and legal on the outside, it suggests a significant degree of induced camber. Either the shocks and/or springs are worn out and not doing their job or something else is going on. What shocks & spring rates do you have?

Is it possible you are getting some chassis frame rail flex (spread) under load? I have also seen lower a-arms start to physically pull through the chassis rail. Adding in one of the cross braces designed to fit in that area might help stiffen up the rear chassis.
