Are the s9 rear coilovers for the x7 cressida actually a 'coilover' or is the spring seperate to the shock (same style as the stock rear suspension).

ok, but the stock suspension setup is a seperate spring to the shock, so in a stock situation, the shock doesnt take the weight of the car, the spring does, but when you use the serialnine coilover in the rear, because it is a 'coilover', the weight of the car is then put through the coilover, which is fair enough, except that the car is not originally designed to do that. Wouldnt you have to reinforce the top of the strut tower and the bit where the bottom of the coilover bolts to? I just think its abit of a silly way of doing things, especially when the top of the coilover only has one bolt going through the top of the strut tower, as opposed to the usual two or three. In my opinion, wouldnt it be better to go with an aftermarket seperate spring and perch to shock? like it is stock? Or if you wanted to go with a coilover, modifying the top of the strut tower in the car so that it is stronger and can preferrably have two bolt holes atleast, and having a proper top hat on the coilover?
I basically just want to know if anyone has problems with the s9 rear coilovers, not the coilover itself, but how it works with the car, and if the car continues to break when using these coilovers. It just sounds like a stupid design if you dont plan to modify the car itself.

Maybe your internet isn't equipped to go to the actual site and look at the actual product and pictures but I did it for you. Hmm 9 seconds of searching, simply amazing.

Ok no seriously. stop. Just stop. You'll learn more if you figure it out for yourself.

I like you.

Okay, well you don't need to know how the diy weld on strut tubes work (they're meant for the front).

You seem to have very good intuition about how much force the stock suspension and chassis can take so I don't know why you'd think someone would make a product which welds to the stock strut tube in the rear (mainly because there is no tube its just the damn pencil-dick shock...)

So now onto answering your question...

These two beauties right here are the serialnine rear upper coilover perches (1 for each side of the car). And you weld these onto your chassis.


Posted Image
Specifically, you weld those perches onto the flat surface which surrounds the stock shock absorber. By doing this, you enable the weight and stress from the coilover (which you seem to already know is a decent amount) to be distributed and all that jazz so your coilovers can function properly without f'ing up your chassis.

In conclusion, the coilover

mounts in two places. To the rear control arm via that spindle at the bottom which the stock shock also mounts to. And at the top the coilover's adjusters come through the hole into the trunk where you'll place some nuts and a bushing, while the actually weight/load of the rear of the car rests on those upper perches.

All of this functions extremely well and gets the job done. However, there's multiple ways to do anything having the spring seperated from the coilover like stance's kit for the ma60 is another way to go. I'm not too sure what the pro's and cons are between the two.

I hope this helps clear things up.

Anyone that thinks that a stock shock mount isn't strong enough to take the full weight of the car are seriously uninformed.

When you hit a bump, the shock absorbs way more force than the spring does.
The spring never exerts more than the total force that it can push when fully collapsed.
A shock has to take the same force multiplied by how fast the load is induced in a formula used to figure Kinetic energy, or inertia.
It can easily be 10 times the static load.
Sorry you all skipped taking a physics class in school, it would have helped you a bunch.

Yeah retard I linked you to the x7 suspension page on their site, open your eyes and scroll through the parts, it's kinda like your search function abilities on here too. Oh wait you don't have any.

Here you go just in case you still can't figure it out.

Not sure if serious..

I've had my s9 coils for about 5 or 6 months now, my only problem is that the strut tubes were threaded with the wrong tolerance so they're super tight on the front coilovers... I've bent about 5 or 6 coilover wrenches because of it.

Other than that, they are stiff as fuck and don't hurt the strut towers or anything.

How the fuck do you spend 1500 on some coils that are made to the wrong tolerance and just accept that shit?

Because I thought G wore down the coating on the inside of them so they'd thread properly. They threaded fine for about 3 inches but after that it was kinda a nightmare.

G is going to replace them and give me a new set when he gets the new shorter tubes in.
