Hi Mark,
Finally somebody, who use TRF shocks...
Keep in touch, I use them since January also.
Springs Asso, TRF pistons drilled 1,5mm front-rear ( I wanted to simulate more less the flow capacity of the Losi red pistons and it seems on bumpy, slippery tracks works better as the original 1,3front- 1,4rear holes)
Sure indoor carpet I use the original pistons.
Now Im working on to test some rebound, since I did not used it.
As I see mainly the blue velvet

, what dominates on your X6sq...
