STI front vbar and rear draw stiffener?
 

Has anyone installed the oem rear draw stiffener and flexible front bar? Did you notice any driving improvements?

I recently watched a subtitled video on YT that suggested the rear draw stiffener makes a noticeable difference on the characteristics of the car. They did not go into specifics on the front bar however.

I stumbled across that part too and wondered if it really performed as advertised.

Another part I've never seen before on other platforms and questioned its effectiveness is the door latch stiffeners and shims.

I know a bunch of people with old NA/NB miatas will run the door latch doohickeys to stiffen up the chassis a touch. That said, compared to a modern, nonconvertible platform like this one, they are not nearly as stiff from the factory.

I installed it.


Negligible differences in ride quality. However, there is less NVH after the install.

Interesting to hear that it cut down on the NVH. I would have thought it might go the other way and increase some of the noise/vibration by making the car stiffer.

I think it may be the rubber boot that covers the joint? Idk. At any rate, less NVH is always a positive in my book.

I don't get the rear one. It's out in the ass end; well beyond where any stiffening is going to benefit suspension geometry.

I may be wrong, but up to a certain level adding stiffness allows the suspension to absorb more of the impacts instead of your chassis also flexing to absorb them.

Your suspension is silent, chassis flexing is not.

I'd be more interested in the tower strut they have, but yet to announce one for the new model. Actually I wonder the the old one still fits as the height of the intake plenum has changes hasn't it?

I came to the same concern - I'd like to get the four STI parts together (V bars, strut brace, front & rear draw stiffener) but lack of confirmation on fitment on the brace and front stiffener on the ZD8 are keeping me on the sidelines. It looks like it would clear but yeah.. dunno.

The v-bars that come on the car are the same part number as the previous gen. Look at the Subaru parts website, and it lists that they(stock solid v-bars) fit all models of BRZ.

I have the '18 tS flexible v-bars on my '22. Only caveat is they are all black. No bling.

Front draw stiffener will be a no go as there are extra stiffening braces on the '22 model where this will go.

The rear draw stiffener is listed as ZC6/ZD8 compatible.

I can't confirm, but I'll bet that the strut brace is a direct fit.

Cheers Dragoon, I saw your PM, too. I'll be the guinea pig and bite the bullet on buying the tower brace. I ordered it with the rear draw stiffener and V bars. The all black tS units are cheaper, $415 shipped, compared to the bling ones which are about $470 shipped with customs, but figure I'll splurge so it all comes in one package.

Will be here in a couple of weeks, will report back on the units, fitment and feel.

Good luck. You can always sell it. I only worry that is why they haven't made it available, because it is a slightly angled low one for a tower strut, it doesn't go straight up, it kinds keeps low and angled.

Exactly. It doesn't even tie into the suspension at all - it's on the rear of the body, behind the rear bumper...? Makes no sense to me what it's even supposed to be doing, unless they're saying the rear of the body stamping is pulling apart under cornering loads. :iono:

There's a good picture of it installed with the rear bumper off at this link on Subispeed's website.
