Never heard of them.
The issue for most Carrera is the height of the entire guide system, not the depth or length of the blade.
They are mounted too high in the chassis and allow too much weight on the front. This makes the stock blade shallow in the slot, but just a deeper blade is not going to fix the issue.
Changing the system to unload the weight off the front tires and achieve a better tripod effect is where the performance gain is to me.
