GR86 Subframe centering Kits

[GRistopher]

I read in a post on another forum that someone had used these after they found their car to be quite lob-sided from factory. he said they made a lot of difference evening everything up

There's a kit for both front and back

Front:

We use this on all of our drift and race cars. Subframes can be up to 6mm off center which can effect the balance of the car and cause the subframe to shift around throughout the day altering the alignment. Also importantly for us, alters the wheel fitment from left to right. Inserts into the...

They're not cheap but they may be a solution if anyone finds their car to be uneven. I know the rear of mine isn't the same from side to side. Has anyone used them before?

Rigid collar kits. Common on the Type-R's and some have said they make a difference. Have thought about them. Should be able to get them on the import sites

I'm not sure how much sense it makes on the rear seeing as the subframe is suspended on big fat rubber bushes? The front i do get but not the back. I was fortunate that my alignment was spot on when I had it checked.

Revolution do a set of centering bolts for the front cross member.

Unfortunately they only do centering collars for the rear, which would likely add a load of NVH.

My rear subframe was uneven before but was fixed with getting Whiteline polybush inserts for the subframe bushing.

I would do that first before rigidcollar. On my S660 track car, the Spoon rigidcollar made a noticable difference, I do plan on getting it for the GR86 one day.

I’d get the power flex inserts first, as a intermediate step between “much stiffer” and “unbearable noise and NVH” as this will add a lot of the latter.

Rigid collar does not add NVH, in fact from my experience they noticeably reduces NVH for me.

If you are on stock subframe bushing, I do doubt that it will do anything at all. As they are very floppy, and the rigid collar only helps to centre the bushing centre without adding stiffness to the bushing.

Solid metal bushing like from Revolution would be ideal for me, but having to press out the existing bushing from the subframe is a major task compared to a slight down of the subframe and slide in an insert.
