thanks for the input guys! as always very much appreciated!
i guess they are not topping out!! good to learn the correct term for it
it sounds like having a bit of play in the spring while suspension is not fully compressed should be fine. what i'll do is i'll lower the rear a bit, preload the suspension as if the car was sitting on it's wheels and then start taking that preload off and see how much the wheel would have to hang before the spring is a bit loose. i really dont think i can get into that situation on the street though, i dont rally the thing and wont be flying anytime soon so i will probably never be in that position.
I have monotube shocks and the perch has a locking nut so it wont move for sure.
i'm close to getting it where i want it and it's been a fun process, i've learned a lot and am grateful for it. more fun than just buying stock suspension
