what camber plates are you running?

Yes, car is on the ground w/the full weight of the car on that corner. There is no gap in the spring assembly-lol. What I mean is that when you assemble the c/o out of the vehicle that there’s no gap between the collar/spring/top hat assembly. You have to preload the assembly slightly to account for any possible unloading situations on the street/track. That being said, the assembly is set up w/minimum preload on the spring...meaning that if I were to loosen the collar any more than a couple/few turns, it would remove all preload in a fully extended position. You have to at least maintain a minimum amount of preload to prevent things from crashing together when you transition from loaded to unloaded and vice-versa.

Here’s how it’s adj currently w/minimum preload:

Ehhh, what’s hung up where? The camber plate assembly is fully seated on the shoulder of the strut piston. Yep, I have 6” springs, but they’re rated @650lbs. Just spit balling, but could it be that the 650lbs springs don’t allow the vehicle to sit as low as a 400lb spring? Does 250lbs make that much of a difference in ride height-lol. I will prolly end up backing down to something lower as this is primarily a street car.

Right, but if I loosen the collar any further, there will be zero preload on the spring assembly. Am I crazy in thinking that there has to be a minimum amount of preload to account for possible unloading situations-lol.

There does not need to be preload on the spring. However you may get noise if you ever experience full droop on the street.

Whuuuuuut!? Thatís counter to everything Iíve heard and read. I had an adj. collar come loose once on one of my other vehicles, and it made this horrendous racket every time I hit a bump or abrupt dip in the road-lol. Even so, it appears that the collar would have to be almost completely at the bottom to achieve the ride height Iím looking for...something just doesnít feel right here.
