I was wondering what the differences are between the TWM Bushings (http://www.twmperformance.com/bushingkits/scion-bushing-kits/scion-tc-2011-and-up-bushing-kit.php) and the TS Bushings (http://www.torquesolution.com/Scion-TC-Shifter-Bushings-p/ts-scb-404.htm). I am curious about the differences made, if any, and which one would be more practical.

they all do the same....which stiffens the shifter for more precise shifting,but some could be made from different material...thats all

What he said

TWM's is made of bronzoil while TS is stainless steel, I believe. Either way, you're getting away from the stock rubber bushings, which is the key.

The advantage of our Bronzoil Cable Bushings (http://www.twmperformance.com/bushingkits/scion-bushing-kits/scion-tc-2011-and-up-bushing-kit.php) is that the material is more solid than Delrin plastic, yet has self lubricating properties which is key for the contact between the actual cable and the bushing. It is the perfect material for this type of application!

Both bronze and Delrin are solids…the phases of matter are; solid – liquid – gas – plasma there are amorphous solids that are not classical solids like jello. Other than that, there is no quality associated with any of the phases…more gaseous, liquidier, etc. Neither bronze nor Delrin are amorphous solids, both are classical solids.

Both materials are self lubricating. Delrin is a polyoxymethylene first developed by DuPont. It is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.

And there is no such thing as a perfect material…there are only two ideal materials; balonium and unobtainium - you used neither...

that may have been a bit overly hostile.

...Except bronzoil is porous and oil impregnated. It's been a while since chemistry, but last time I checked oil wasn't a solid, but a nonpolar liquid. Also, delrin isn't really self lubricating, but has a very low coefficient of friction and usually doesn't require lubrication.

tl;dr hurrr durr I can use wikipedia and try to bash people on the internet. both parts will work fine.

Bronzoil is made from bronze; Dodge just came up with a way of making it porous and calling it Bronzoil and then getting it trade marked in the late 1940s. To take advantage of that porousity, one has to add oil to the finished product. It is not machined with the oil in it. That trapped oil will create a hydrodynamic bearing – but the shaft has to be spinning at realatively high speeds for that to happen. These “Bronzoil” bushings are used on shifting linkage. It is not even rotating. It will just articulate as you move the shift lever. Therefore this is not the best application of this antiquated technology.

Reread my post…I never said that Delrin was self lubricating. I used the words “low friction” and as you correctly state, “don’t require lubrication.”

I’m not bashing anyone. I’m just pointing out deficiencies in what is written…just like I’m doing to your proes right now.

I did not use Wikipedia, but I just did to make sure…Bonzoil is not even in there…

I do agree with you that both Bronzoil and Delrin will work fine…it’s just that TWM_Performance stated that Bronzoil was the “perfect material”…and that is BS!

anything is better then stock bushings case closed....if you compared the two on the car,you wont notice a difference...both does the job...

And there is no such thing as a perfect material…there are only two ideal materials; balonium and unobtainium - you used neither...


LOL...

And then there are the shiny Stainless Steel bushings that NST offers:

The NST bushings for the tC hit the market in 2005/2006 and
the same bushings will work with both the first and second generation Scion tC.

Delrin bushings for this application will last longer than the car will. Delrin is some amazing stuff. I used it for custom making 1/8th scale R/C parts. It's virtually indestructable, very lightweight and fairly easy to work with. It resists heat very well too. I chose the T.S. Delrin's for the price first and foremost. I was also skeptical of putting metal bushings in this application. I did not want to chance the metal bushings causing other parts to wear under harsh conditions. Probably never happen though.

Just sent a payment for NST bushings. Not sure if shipping is usually free but it was today. Free shipping always makes everyone happy. These should go well the the trd qs.

I just settled with TorqueSolution's bushing because of the previous comments and price difference. Haven't installed it yet since I've been busy with school, but I'll probably give an update on them if I feel any difference.

Thank you! And yes, we are offering FREE shipping in the USA this month :)

I installed the TorqueSolution shifter bushings yesterday and I felt a noticeable difference. Shifting was pretty crisp and solid; also i felt more vibrations from the engine. The install was pretty simple and straight forward, especially if you just follow the video posted by TS. Right after I installed the bushings, my shift boot fell out of its place but it wasn't too hard to figure out how to put it back, so that's something to watch out for if you accidently move the cables inside the engine bay. For some reason my stock bushings were a bit melted and torn up... could it be because I learned how to drive stick on this car?

I don't think so. Sure, you may have worn out your clutch a little at first, but the good news is you have an excuse to put a better clutch in sooner! As far as the stock rubber/plastic bushing; mine looked like poo when I changed mine, and I only had 1000 or so miles at the time. It gets hot under your hood, and rubber does not hold up well in a humid hot environment.

Haha damn I'm not looking to spend money on an aftermarket clutch especially if my car's not even turbo'd... If the OEM bushings are melting under heat, does that mean over time the TS plastic shift bushings will start to lose it's shape and function?

No, Delrin will hold up just fine. If they melt, your tranny is about to or has already grenaded. I only put the bushings on the tranny side. The "feel" was perfect for me with just those. No signs of wear or change in feel after several thousand miles.
We used to bend Delrin rod into roll cages for 12 lb. R/C Monster trucks, the rod would be right beside the engine which averaged 250F, sometimes 300+F. Never had a failure, melted spot, anything..

Oo alright...so does that mean because my OEM bushings were a bit ravaged that my transmission took a beating? Occasionally, when I shift into second, it struggles and grinds a bit.

My choices for busing materials and why;

Delrin – very tough and does not require lubrication, therefore will not collect road dirt.

Polyethylene – same as above, only put second because requires silicone for it not to squeak – current day sway-bar bushings are made of this material.

Stainless steel – most readily available are the 300 series which are very good for this application. Over time will buzz out and become loose because it needs to be greased and the grease will collect the road dirt and ware on the bushing surfaces.

Bronze – include porous Bronzoil here. The only reason bronze was used in the past is because it was softer than the steel shaft rotating within it and it didn’t ware out the shaft as it ran out of oil. The bronze was the sacrificial material that could be replaced very easily and regularly. Bronze still requires lubrication to slow down the ware rate.

Rubber – OEM material…isolates noise and does not require lubrication, but sloppy for performance.

Like always – this is a free country and everyone can make their own choices.

Maybe a little, mention it at your next 5k service. I am willing to bet there is a bad batch of synchros out there in several of our cars. Mine is the exact same way. Let your car warm up for at least 20 minutes before driving on cold days. Best advice I can give you is SLOW down your 1-2 shifting. This car really does not like to be shoved into 1st and 2nd as you noticed. I found that taking the time to insure I have the clutch FULLY depressed before I shift from 1st to 2nd helps. Cold weather makes it really bad, it will ease up a lot in the summer.
I have driven manuals for 17 years now. This is the tightest, p.i.a. transmission I have owned. Most cars will shift very smoothly with only 3/4's clutch engagement. I had to break that habit. I have never felt another car shift this horrid unless the clutch was worn out or a motor mount was broken( Good ol VW Scirocco) But that's another story..
And I agree 100% with EOIO3. Let's just say he knows his stuff, and has proved it to us OG's many a time. He has designed, built and driven vehicles most of us never even get touch. He's not the most loveable guy, but we all have our quirks.

That sucks because I left the Corsportusa shifter bushings in my '09 Tc since I didn't think it would work.

I have a question guys. I have the TRD quick shift which attaches to the tranny. Does any one know if shifter bushings would work with that? I know in side the car they would work but I'm unsure about the tranny side.
Thanks in advance.

Well, the cable bushings are the same ones that would fit on your trd, they are just bronze instead of rubber. I see no reason why it wouldn't, but if you shoot an email over to the sales guys at twm, I bet they can give you an exact answer

Haha you know I didn't even think about that. I emailed them and I'll let you guys know the response. I also asked them about combining the quick shifter with their short throw.

The bushings will work with the TRD short shifter 100%.
