strut and spring drop

[buzz11]

when a strut says it gives u a 1.5" drop, the car is going to drop 1.5" with stock springs. is this correct? if a spring says it gives u a 2" drop, the car is going to drop 2" with stock struts. is this correct? so if i pair these struts with these springs, its going to give me a 3.5" drop. is this correct? sorry but im a noob to suspension. i want a drop but not something more than 2". just want to make sure before i buy anything

No way. Only strut that can give you lowering benefits is the Koni Yellow , and it gives you a drop of 0.25 maximum.
Lowering springs and coil-over sleeves (drop spec varies) , will give you lowering benefits.

I've never seen a strut claiming a drop in ride height. Maybe it's talking about a adjustable spring perch? That might have an effect on ride height. What kind of stuts are these?

[ShayneRizzle]

Yes what you said is exactly correct.
There are a few struts out there that are shorter then stock such as skunk2s and there are even some that lift the car a little like the kyb "drop killers" lol

Unless the strut is taller/shorter it cannot change ride height

The strut dampens the effect of the spring, nothing more.

The strut will never change the ride height, unless the spring perch is lower (such as on the Koni Yellow, with the adjustable perch)

When a strut says 1.5", that means it shouldn't be used with springs that go any lower than that. The KYB AGX, for example... the warranty is void if you lower your car more than 1.5". They also will not respond very well, and may blow if you go lower.

Lowering springs should NEVER be used with stock shocks, PERIOD. Don't even consider that an option. The spring manufacturers sure don't.

the skunk2's are a short stroke/body strut that are designed to accommodate the shorter travel of a lowered vehicle on lowering springs. paired with stock springs there shouldn't be a change in ride height. the "drop killers" height are most likely due to an improper measurement of spring perch on the strut body (my hypothesis) by the manufacturer. this would be the same idea as the koni "yellow" sports that have the adjustable perch that may be moved up or down from the oem spec location on the body.

buzz11: springs are the components that will offer the ride height change. the only exception for the struts are the koni yellows. you also have the choice of coilover sleeves (e.g. ground-control) that offer a range of height variation. if you've got the money, pair those up (yellows and ground-controls) and you'll have all the lowering you want plus reliability if taken care of!

p.s. where did you find this information that the strut gives you a certain amount of lowering? i'm just curious.

I believe he misinterpreted the part that says the AGX is good to 1.5". It means the strut can withstand that much of a drop. He took it to mean that it GIVES that much of a drop.

ah... makes sense.
