Hub to fender measurements?

How high of a lift is too high to start damaging or causing problems? I've heard hub to fender measurements of about 24"? I have 888 coils with 5100 up front and would like a tad more lift so thought about dropping a small spacer in there but don't want to push the limits. I do have SPC LR UCAs as well.

 

3 inch, 23 hub to fender on 2nd gens is about the max, further, CV find start to rub, topping out shocks and harsh ride. People with 4 inch lift in the front, ride cant be that good, lack of downtravel. What hight are you at now?

 

3rd gen but last I checked rear 24 FD like 22.5 FP 23, I tried a 1inch spacer but took it right out bc the cv angles just looked too much haha but I do have the 1/4 driver spacer in and was gonna our that on oasenger side and a 1/2 on driver for a total 1/4 bump in front just for a 1/4-3/4 rise.
