Changing Slider Mounting Point Birdcages

[Matt49]

Best answer so far and actually tried it. Thank you. Any other input you have would be great! Also find any sweet spot and just leave it? Shock in front higher or lower than the slider behind? Thanks!

Not to answer for him but usually your shock in front is going to be a little higher on the birdcage. If it's not, you usually run out of shock travel before the chain grabs (not a good thing).

Even shock height I believe would matter for valuing higher or lower right?

i forgot to mention that i run a left upper shock mount that is 1-1/2" LOWER than standard.

if you are only changing the lower mount on the rear shock you shouldn't have to change anything about the front shock lower mount. you won't be changing the amount of birdcage index, you will simply be changing the distance-traveled of the rear lower shock mount for the given index. definitely important to pay attention to all shocks extended though as matt said.

this setup is NOT something you would change at the track. it belongs in the shop

to sum everything up, i would say that if your LR setup allows you to have your left rear spring to be loaded at all times, increasing the radius of the rear left lower shock mount will "enhance" your drive and will probably have good results if that's what your car needs.
if you are typically unloaded and might become loaded with a possibly adjustment throughout the night (dropping left lower bar on frame) vice versa, i do not recommend it.
