Tamiya - 51293 F-Teile (Radträger vorn) TA05-IFS, TB-03 - Modellbau-Seidel

Yes the black C-Hub from TA05.

How about using 54031?

Tamiya - 54031 F-Teile (Radträger) verstärkt TRF416 - Modellbau-Seidel

...

That's the same exact part number I just asked about.

No, that is not the correct information.
You learn the differenz when you buy them :p

I drive them all time in my TRF and have no problems since i know this from a club member. Also you can see the last years since i post setup I use this C-Hub in any setup on petrirc or on my youtube post :lol:

But the front XRay works BEST!

Unless you're running a TCS race, get the Exotek hub. They are great. If you are, order the hubs from the TA05.

Those two options are the way to go.

I'd caution against that.

The exotek hubs are great if you can gaurantee you're not going to hit anything or get hit.

I bent mine immediately because I do hit things. Tamiya sponsored driver at 702 also bent his real quick and he gets hit because of inexperienced drivers

Since I switched to the 51293 TA05 IFS standard ones, they stopped breaking. In fact Im now breaking the steering upright instead!

Also for those who switch to the IFS, I recommend the 54490 flange tube (4.5 x 3.5) for the top.. it saves you the hassle of putting in the spacer between the flange tube and steering upright.

Simmi I don't know what you are saying. I was pointing out to Stein that only a few posts prior, I asked about that exact same part number.

Tamiya TRF419X - Christian Donath - ETS - Trencin - 16-18.06.2017

That's great!

Anyone know what the progressive springs are that he used?
Mentions SMJ's

For 419x the short set.

It mentions he used progressive SMJ's, I was wondering which progressives?

Most others I've seen used red. But I wouldn't​ be surprised if he was using the harder set(pink or purple) as well since he thought the Tamiya springs were too soft.
