Chain/Shock Question

[racehard24]

On the left rear is there a max angle I should let my left upper bar be at full droop by setting my chain? I have heard 45-50 degrees and we have way over that. I am just worring the car is getting up to high. Also I am just a touch tight in the middle on the gas and just a little in. If I went from a 6-3 LR shock to a 8-3.5 will this fix this?

45 to 47 is what ive always been told. A shock wont help that much. I think you need to look at someway of limiting the car
