OMGHi2U New rear bushings by Turn in Concepts

I recently stopped sniffing glue and decided to focus on small improvements in my aging car. As much as I love her, my 2004 WRX wagon is getting long in the tooth, with her flipping 200,000 miles this upcoming week. So....what had happened was...

I was visiting Andrewtech Automotive a month ago and stumbled upon some 2005 Saabaru wagon rear suspension in their bone pile. This got me thinking that my stock bushings were probably janky. Andrew was kind enough to allow me to jack the rear lateral links and trailing arms. Since I was already in a shop, I decided to press the bushings out there, which I did with Andrew's assistance. I took them home, cleaned and rattle canned them and tried to scam some bushings for Free 99 from Clint at Turn in Concepts. He told me to "suck it Trebeck" and I started saving my pennies. Several weeks later, I received the black race lateral link and front and rear trailing arm bushings via FedEx. This happened to coincide with my next visit to Andrewtech which was apropos.

That was this weekend and this is not so much an install thread as it is a slight review and supplement to these gems:

My install advice/deviation from above are as follows.

1. Don't be a hero and buy new lateral link/rear hub bolts (20504AA001). (2)
2. Don't be a hero and buy new lateral link/rear hub washers (900335056). (2)
Reason for 1/2 is the rear most bushing WILL be frozen to the bolt and its a whore to get off which frees both the washer and the whole bolt for reuse. Unless you have a grinder, a steady hand, some skill with grinding, a vise, a chisel, and mechanical skill in general....the odds of you buggering the bolt/washer up are high and even if not, its a whore to do. Depending on your dealer, this expensive hardware should be under $40 all in.
3. This job requires work on big and tight suspension bolts. These are a whore to loosen. If you have experience with hard to remove suspension bolts, sally forth. If you don't have experience, you better eat your damn Wheaties and have a 6 foot pipe to slip over your breaker bar.
4. This job requires removal of the OEM bushings which can be fun or a whore depending on your skill/experience. Luckily for me it was a snap as Andrew's shop has a bitchin' press and an infinity of sockets and round stock for pressing.

The rear trailing arm bushing is cake using a Pitman arm puller. I got this jank at Harbor Freight for $15.


Dem bolts. Dem washers not pictured. Yes...my local parts guy usually orders stuff under Big Ron!


Washed, etched/primed, painted and cleared stuffs.


Suprize! Silicone is the lube to use and I anti-seized the inside of the honking metal sleeves.


Parts


Install shot, blurry due to heavy drinking.


Alignment. As you might guess, the new bushings make your rear end all cattywhampus.


After the install I drove 4 hours back home with most of it being highway miles. The rear end is SUPER firm now. As in I'll likely dial DOWN the Koni shocks to a softer setting. For the first 20ish miles the whole rear was SUPER creaky, then once on the highway she's quiet as a mouse. Upon arrival to Virginia Beach, its only creaky on slow speed turns but its neither super loud or super annoying so I'm happy with choosing the black/race version rather than the gray/comfort version. I now have 100% all aftermarket bushings in the rear end and can honestly say that these have done more for the suspension/handling than all the other bushings combined. They make a REAL and APPARENT difference.

***DISCLAIMER*** I swapped these out due to concern for the age of OEM units and not for racing/being cool. My idea of racing is hauling fill dirt from Home Depot. All of the OEM bushings were fine in appearance (a few got janktified due to unkind pressing methods) but had the same firmness as the bottom of a tennis shoe. The black/race TiC replacements have the same firmness as a bowling ball. Your mileage may vary, void in Canada, don't run with scissors.

Amazing how the smaller things you upgrade on a car can be so noticeable though. I'm planing on slowly "upgrading" all the soft rubber parts on the car for newer poly or aluminium bushings. I'm still young and stupid enough to like the sound of my axles rattling in my teeth.

i would warn those of you who dont have any experience with the RACE duromer bushingss....these MAY be a BIT harsh for many of us here for dd use

the NVH WILL increase and MAY increase to the point of

BEWARE......you have been warned!!!

no..im NOT kidding

and there ARE factory 'group n' RUBBER busings available that are MUCH better than stock and WAY less harsh than urethane....these are what most of us would consider FIRM

Personally, I'm kinda amazed there aren't more reviews written like this.


Read as "more reviews by Unabomber are requested/required".

There are two 40 year old threads on this very board by williaty where these mods are described in vast detail albeit with the more desirable Grp N bushings.

I thought of this too, but here's my line of logic:

1. Group N bushings are more expensive (I'm pretty sure) and as one piece bushings are a whore to install as you have to have an excellent press and a well sorted set of press fittings to install without mangling them. Though haters will disagree, these are not a DIY application for 98% of Subaru owners and would require professional installation which is $$$.
2. My wife refuses to drive my car so noise/creaking is not an issue for me.
3. I don't find the low speed creaking to be loud or annoying, BUT if this is done by Average Joe as a bushing swap vice performance mod (like I did), I'd assume that their gray/comfort bushings are dead quiet though I don't know. This would give you the "Group N" quiet for less money and much easier install.

This is an opinion of course as what is acceptable to me is not acceptable to others, but I have no issue with these in a DD car....when it doubt though, get the gray/comfort option.

They actually said the noise difference between the lateral link bushings gray(comfort) and black (race) was none. Just emailed them about a week ago after I was unable to find them on the website. Not sureabout the trailing arms but thought I would add this as I am anxious to swap lateral link bushings with those.

@ Unabomber

I just replaced the same rear bushings and I have ZERO noise.

Greg from TIC told me that the best lube was MPT Silicone/PTFE you might want to try that if the noise ever starts to bother you...

I used Oatey pure silicon grease on the rear trailing arm race poly bushings. The stuff is thick,smooth,and adheres to surfaces so it stays put. I'm curious how much the impregnated graphite in the TiC bushings actually contributes to fighting friction. These bushings are quiet but the pillow ball fronts on my trailing arms rattle a little at low speed/pulling in/out of a driveway.

I've been using the CAT Desert Gold lube on my sway bars, and I dont think I'll be using anything else on poly parts (I'm not a huge fan of poly in the suspension links anyway).

It's pretty expensive though, but it lasts.

i guess ive grown out of wanting to drive a race car on the street

and all ya really need to install the group n bushings is a press, some grease and an assortment of sockets and washers

but anyway....i think ive got a broken motor mount

I've got the STI lateral links on my old GC, and well.... they are completely freaking awesome. You don't need a press to install them, they are completely utterly squeak/creak/etc free and since they have pillowballs (heim joints) they are way stiffer than group-n and a smidge stiffer than the stiffest poly bushings. Except for my rear sway bar, they are my favorite mod. Also they are pink.

The thing that nobody ever says in these reviews is that if you do group-n or if you do poly bushings, you basically get to stay in relative stock Autocross classes. My bitching STI links bump me up into SM where my stock engine 2.5rs is giving up 200HP to competitive cars.

Soooo, if you want to drive a race car on the street. And you want to drive a race car on the track. And you want to win... These race stiffness poly bushings are a great idea.
