What's your build date? MY2014, I presume? This was after Fuji Heavy upgraded the subframe bolts I'm guessing.

Yes, MY2014. Bought it last Feb.

So, do they really works?

Theys works fors the spoons bottoms lines.

The collars are magical. They turn the FR-S struts into double wishbones.

I have some concerns. Also I have almost all bushings from Whiteline and some more stuff to sharpen my handling and I have doubts I will see a change after collars installed. Any of you guys who has collars and HEAVY changes in other suspension parts see this mod worth the money?

Yep, you listed Whiteline. That doesnt say much, same for your other stuff, it looks a little bit messy for my taste (no fens). And from the mods you have I would say your priorities are elsewhere, again, no fens.

How would you describe difference after installing them?

These surfaces aren't planed flat nor are they perfectly parallel. The rigid collar's cone actually helps support the bolts, and prevent shearing, while the washers actually lock the mating surfaces together.

Uneven mating faces?? The body is a pressed steel welded construction that is built on a jig. Every assembly in the world requires tolerance, hence the clearance on the holes.
The bolts on the rear subframe pull up through machined steel tubes mounted in rubber bushes. Any angular misalignment of the mating faces is taken up by this rubber. Even if you fit uprated bushes, the bolts will still pull the bush square with the body, and the rigid collar will squash evenly, giving the same result.


As for the front subframe.. how on earth can a solidly bolted component, being removed and bolted solidly back into place with what is no more than an aluminium washer improve ride or jounce??? in fact, I would say that shock loads through the stock assembly are less likely to move anything if they don't have an aluminium washer in place??

I wish I could answer that question with data, but when three individuals, who are regular passengers in the car, notice an improvement in ride quality, that's no coincidence.

I'm trying to find some for my other Toyota cars

No one is forcing anyone to buy these rigid collars

Not exactly a double-blind test. This screams snake oil. And KoolBRZ likes it.
