XRAY - Model racing cars

any racers used the ecs front driveshafts for the xray t3 ? are they worth upgrading to from the standard xray driveshafts

I use them most of the races. I think it gives the car a smoother feel and it's easier to drive. You can run more lock without the car making rough turn-in's etc. in low speed. I think they are worth the upgrade for sure.

I want´t to buy also the ECS Driveshafts, and i see that Alex Hagberg also drives with them.
But i have a questition about the lifetime from the pins.
By the normal driveshafts there is a 2mm thick, and by the ECS is a 1,5mm pin.
Is that possible to drive with them with Modified Motors also for long time?
I see any people that they take in the front also a Diff with 1.000.000 Cst Oil inside, but they don´t have a spool.
Before i drive Xray i tried by my Tamiya 416X also ECS from Spec-R, but they was bad.
After 3 Rounds the pin was broken.
How it looks with the wear-out?
