My concern is durability. As MikeR stated these pill inserts are a down grade to the bushing. They won’t be as durable.
Its the have and have nots.. the other guys switched.. so Tamiya listened..
Next up will be a mid motor conversion lol

with the idea of the plastic pulleys having give I assume you mean in mod? or do you feel its happening with stock (21.5) on black carpet?
How much weight did the alloy rear diff add? I have never really had any leaking issues with mine but the idea it will keep the temp down and the feel more consistently the same during a run would be a bonus.

Tried it, and its slightly better but still getting negative rebound. Honestly, I might just get TRF418 damper stays and run the regular dampers. These SSBB dampers have been such a big fuss for me, and it doesn't help that TRF parts are always scarce. If I broke a bulkhead I'd probably just jump ship to another brand since I wouldn't be able to fix my car without buying a completely new one. It's damn hard to be a Tamiya fan nowdays

Those dampers are leak free I( maintance free,almost!) with zero rebound and no play at all in the piston. Why can't tamiya design new Dampers like those. I have now 2 sets off these SSBB,but I will sell them because and cant seem tho get them leak free and without air in it.
I love tamiya and they definitely got some great dampers,but these SSBB are just a waste,for me at least.

I really think those dampers are terrible, a lot off play in the piston,no wonder its a pain to get them leak free and without air. I run black Xray dampers on my trf419x because of this.

Tamiya has released TRF aluminium rear uprights.
They are available in 2 and 3 degrees.
What is the sense of setting toe in via upright?

But then it alters also the wheelbase. It's not a simple either or decision how to set rear toe...
#4391
From my experience, inboard toe has different effect than outboard toe... Aside the fact that the rear arms are working differently, it makes a difference in corners. Outboard toe make the car pivote, it could be helpful on small pac-man carpet tracks

If theres one thing that could be pinned at the top of this forum, its use the clear orings lmao. I learned my lesson 😅 and I took a trip to the forum pages from 2017 and its all about people complaining about the blue ones, and being suggested the clear orings. Even the big bore dampers I got for my FF03 (comes with blue orings) and have been built very carefully with air pumps and very nice muchmore shock grease have started to leak even before a race day.
Don't get the blue orings, don't get the x orings, just listen and get the clear ones for godsake.
Another bonus tip that people might overlook, is tap the bottom of the adjuster (looks like 54489) properly. Dunno if this has been talked before, but I've accidently tapped one slightly crookedly and it made the piston shaft scrape the rod guide on one side and started leaking way more.

To prevent scratches in piston rods, Tamiya has this nice tool:

Although the clear Tamiya orings are leak free, they cause a lot of drag on the shafts, especially initial sticktion.
Personally I have switched all my Tamiya dampers to using the Yokomo blue orings YS7-HG. They maintain smoothness while allowing only minimal leakage compared to the others I've tried. They're a bit larger than the TRF blue, and are softer than the clears.
