Help Needed: AST 5100 Coilover Install

[DeathBear]

Hi All,

Here is my setup:

AST 5100 Dampers with Springs Upgraded 61mm ID Springs
Front: Spring Length: 180mm, Helper Spring Length: 100mm
Rear: Spring Length: 200mm, Helper Spring Length: 100mm

Front Dampers: The question I have is about adjusting ride height and preload. If the ride height is adjusted (lower) when the car is on the lift or full droop, the spring is loose and has play, no preload, and will need to be guided into the spring perch before it is loaded and on the ground. Is this normal/ok? If yes how would you preload the spring?

Any help would be appreciated!

Thanks!

If the ride height and pre-load are adjusted together, you may need a low/no rate helper spring to keep the spring from flopping around. The helper spring should keep the spring in contact with perch at full droop.

Thanks! So if I understand correctly, a longer helper spring is what is needed correct?

My other question is would it be fine for the spring to be loose under full droop or when the car is lifted if I leave the setup as is? I don't anticipate the car to be lifted during normal driving.

Thanks!

Should not be an issue. My setup on another vehicle was the same(no helper springs) and the only thing you need to make sure of is when you lower your vehicle your spring seats straight on the collar.
