Like you could see on my car from the last French Nationals and on my setup sheets, I use carbon fiber shock towers for some time now.
Part numbers are IFW631 and IFW632.
It's the latest option from Kyosho for Inferno MP10 and MP10 TKI2.
ADVANTAGES
After a lot of testing on different tracks, I find that these new mounts give the car more grip and also better damping.
In fact, due to their flexibility compared to aluminum, the use of carbon gives the car more general grip.
The model I currently use are the part numbers IFW631 and IFW632, to go with the 50mm front and 58mm rear type long shocks (original on the MP10 TKI2).
As the towers are thicker than the original aluminum version, the shock mounts have changed.
I use the short high shock mounts for the front (IFW633 shipped with the carbon mounts).
However, since I usually use the IFW612 option on the rear (XL mounts), I went back to the original long shock mounts, part number IF346-04LB to find the same angle of the shock versus the arm.
DRAWBACKS
So I think these new towers add something to the car, but it is obviously not an essential option because the original aluminum mounts are already doing their job very well.
However, this can allow you to fine-tune your setup, or an option to study during a TKI2 upgrade for example.
On a reliability level, I advise you to reinforce the top of the fibers thanks to the application of a film of cyano glue (for tires) on the outer edge. It will prevent its fragmentation during errors, especially on a very abrasive surfaces . (see video)
Once this operation is done, the supports will have the same lifespan as its aluminum brother, maybe even longer because they do not bend.
You can trust the entire Kyosho team for the reliability of the choice of material and thickness used.
If I had to give these new mounts a negative point it would be the small loss of precision that is brought about by the rigidity of aluminum.
You will probably need to modify the setup of your car slightly in conditions with higher grip.
Last thing, during my tests, since the supports provide more grip, the car tends to take more roll.
If you use these options I advise you to increase the balance of your anti-roll bars by 1/10.
For example, my basic setting is 2.3mm in front and 2.8mm in the rear, I prefer now a 2.4mm/2.9mm setup.
See you soon for new tutorials!
