TRD lowering springs bottomed out?
 
Hey everyone, I did a quick search and couldn't find any answers or close up pics so I'm asking here.

I bought some TRD springs pre assembled on OEM shocks. When installed recently, I noticed both rears have about 6 coils at the top of the spring fully compressed on level ground with no extra weight in the rear.

It doesn't seem normal to have the springs completely compressed like this, has anyone with TRD lowering springs had this issue? Can anyone think of a possible cause of the problem or fix for it?

That part of the spring is used like a helper/tender spring. It makes up the slack in the assembly.

100% normal, just there to take up space so the spring doesn't move around with the car in the air.

Apparently this was a pretty dumb question, but if somebody can school me a bit further; These aren't off road vehicles that require 6+ inches of wheel travel, yet every car I've had will raise 4ish inches before the wheels leave the ground when lifting with a floor jack. What is the purpose of having the wheels sitting on 2-3 more inches of travel beyond what the rest of the spring can offer? I don't know if that made sense... :bonk:

Basically, what is the point of this design if a portion of the spring can expand but not compress under normal load?

Less spring to travel means less flex and a firmer more stable platform.

cut off 4 coils and you get a "free" 2-inch drop :cool:

These cars just don't have much bump travel.

When lowering the car with springs, you trade bump (compression) travel for droop (extension) travel.

You need droop travel to keep the tires on the pavement as the car goes over bumps, undulations, etc.
