I absolutely love that picture!

Team Houston86.com has been on a roll lately with our functional mods. Today we present a more challenging yet worthwhile upgrade to the rear suspension. These inserts fill in gaps between the rear member sub assembly [RMSA] and the chassis. This connection is important because all the suspension bits are connected to the RMSA as well as the chassis. Any give or flex reduces response of the car because the car has to waste energy settling itself.

You may have felt this sensation of the rear dropping a little bit when accelerating from a standstill, shifting gears, slowing at a light. That's the slop we are taking out and gaining those precious milliseconds, because racecar.

All of those listed things happen sooner now, and the first few times it was surprising because I did not expect that much of a transformation. In my opinion this, the Whiteline positive shift kit, and Perrin Rear Shifter Bushing completely transform this car. Words like precise, control, instant come to mind. Although the rear is stiffer, I haven't felt the car wanting to break traction and overstreer. It's probably because I'm running 245 width tires. Overall, I think this is a must have mod.

My only negative feedback is that the instructions could use some more clarity. I found it fairly hard to follow. It doesn't even show you where to place the jack for the front set of bushings. At times we had to make it up. However after two installs, we have fine tuned this guide for our community. Hope y'all enjoy.

Thanks @cobrabyte for doing the install on the car while we documented. I greatly appreciate your workmanship and hope you enjoy this mod as I do mine. Shoutout to @post_break for helping as well and bringing his voice of reason. Thanks to @FT-86 SpeedFactory another smooth purchase. Always a pleasure.


Please pardon the lower quality photos, it was dark in the garage today. As always, we are not responsible for any injuries or damage done to yourselves and your vehicle. Please be safe.

Another disclaimer: We used a drive on lift to do this mod; therefore our wheels never left the ground. This suggests that its possible to do the mod with the car on the ground, but there isn't enough room to work the front. If you opt to use jack stands and remove load from the suspension, then the instructions may differ. See below for note

just one jack to control crossmember height is all thats needed, and I placed mine right under the crossmember a bit to the passenger side.

Perhaps if the car was already on jack stands, then a single jack would work. @cobrabyte and I did ours on a drive on lift so our wheels never left the ground and we needed a second jack to create the space to pull and slip in the bushing

cobrabyte 10-29-2012 08:16 PM

Took my car through my usual driving 'circuit' today and can feel an immense difference with these bushing inserts installed. I had originally only installed the rearmost inserts to see if there was a measurable difference in the ButtDyno™. With the rearmost inserts installed, the car feels a little firmer -- especially off of launches. I went ahead and installed the forward inserts yesterday and can report a HUGE difference.

The car flies off the line now. I've daily-driven a Lotus Elise and can say that the car is beginning to feel as quick off the line as my Elise did. It'll punch you into the seat and keep you there. Gear shifts are noticeably better -- more precise. I didn't expect a change there and it's a pleasant surprise.

I simply cannot believe how 8 simple inserts can drastically change the overall feel of a car but Whiteline has come through. Big time. It's takes all the play out of the shift response. You get power -- now. No more wishy-washy feeling.

With power comes responsibility: you will notice the rear end being a little bit more tail-happy but, if you've driven RWD vehicles before, you'll appreciate it. This car has so much more potential and it's fantastic that small, inexpensive modifications like this are adding up huge.

Combine this kit with the Perrin shifter bushing and you've got a great combo. I'm going to install Whiteline's positive shift bushing sometime next month and I'm sure it'll just get better. I'll report back when I've done that.

This is great. I've been considering purchasing some whiteline bushings for a while, and now that there's a guide out, I'll definitely be making that purchase ASAP! :thumbsup:

Totally agree, it definitely does help a bunch when you have an idea of how to install what you want to purchase. Taking the doubt out of mods!

Suspension's just a PITA because of the high torque values and possible rust issues.

This! As you saw in my photos, one of my bolts had growth on it. Barnacles? I think it was exposure to seawater or something during transport. I'm not sure what this means long term.

Yeah I saw that...and you're not even in the rust belt. I shudder to think what I'm going to find underneath the car when I install all these bushings and my RCE springs in March.

Just thinking about how the car transformed after all the bushings and RCE, that'll be a painful wait. The results are worth it, my friend.

Let us know if you find any issues with rust

They like to salt the hell out of roads in my area, so I expect I'm going to need 3/4" or 1" breaker bars or an impact...which I don't want to shell out for.

In any case the plan of attack is to drop the exhaust (redo axleback install and add front pipe), do the Whiteline gearbox mount bushing, rear shifter stay (KB hopefully by then), install springs, rear camber correcting bushes, and the rear subframe inserts. It'll transform the car entirely!

Did you get this from the Passenger side, mine came off looking the same, I did a mini write up on my Journal as well, just not as good as this one. Feels great now

Yes that came from my passenger side. Eerie that we share similar characteristics. @cobrabyte's BRZ didn't have this, but his build date was much earlier.

Mine was in March, purchased in June. Mind if you share yours?

*KID* 10-29-2012 11:23 PM

Produced also in March, bought in June.

Thanks for the write up. These bushings are the ones I am most interested in, however having come from a car with lots of poly-urethane bushings I don`t want to end up with rattles and vibrations like I did before.

Can you comment on any additional harshness of the ride, or vibrations or rattles now that you have installed them? Thanks!

On good roads, its smooth like butter. I don't hear any additional rattles or noise back there; my tires and exhaust probably mask anything that could be heard.

On bad roads, I would say its marginally harsher. Its not a bad tradeoff though; I rather experience some harshness and get instant response rather than wait for the suspension to settle itself after some rocky road ice cream.

Keep in mind, I've done a bit of work to stiffen the ride so I can't comment on these bushings alone. In the rear I have Racecomp Engineering Springs which are fairly stiff, cusco lower control arms which probably contributes minor stiffness, and these bushings. I also have star specs which howl like a wolf all day.

I've put more than 150 miles in various terrain where I live. Overall these don't add any noticable NVH given the amount of modification present. Hope that helps you.

Look like Cuscos in that blue color.

Got these bushing still sitting in the bag. Will have to wait till it gets warmer for me to tackle my suspension. Swaybars still sitting in an unopened box as well.

Dezoris 12-12-2012 05:14 PM

Great write up. If you are going to do any suspension work or underside work, do it early on. With all the stamped steel the underside is going to be a rusty nasty mess in a few years or less if you are in salt and moisture often.

You're right; OP actually says they're Cusco arms. I was looking at the wrong arm, lol.

Installed mine this week (May 20th, 2013). Wished the two packets of moly grease mentioned in the instructions were in the package instead of just one. Waiting new tires and rims so I don't have a butt report. I will install the Whiteline transmission bushing (with Perrin Performance transmission T product) and Whiteline steering bushings along with replacing transmission and rear end fluids with AMSOIL products before getting on the road with Weds 105s 18x8 and 245/35/18 Michelin Super Sports. Looking forward to niceness beyond expression!

Hot Rod Heaven is just one more mod away.

I finished the bushing swap yesterday (6/9/2013). The right-hand, front bolt had corrosion similar to this picture on my November 2012 delivery, BRZ limited purchased at Sewell Subaru in Dallas.

The left side bolt had a light coating of red grease and no corrosion.

Anyone heard a possible explanation from Subaru or Scion? Could this be an issue for Texas or Southwest delivered Twins?

One of my front camber bolts had similar corrosion. I'd consider it a non-issue, but something to watch out for when doing suspension.

Wow! My engineer trained mind starts on a trail to figure the reason for this bolt and this location across platforms and delivery points. Why only this bolt? And why the passenger side only has the problem?
Anyone connected with factory reps?

Thank you for the excellent DIY.
Same Bolt , Same Location May 2012 FRS

brillo 06-20-2013 12:40 PM

I had these installed by a professional shop yesterday (great mod), just be aware that loosening the subframe will likely alter your rear alignment so I would suggest installing these along with other suspension mods and get an alignment shortly thereafter.

eckoflyte 07-27-2013 03:10 AM

Thanks for this awesome guide. Just did mine today using this guide and it was a relatively painless job.
