Spring Rate
 

Anyone know where the black front spring (201 kit) fits in the spring set? ............ i'm imagining it's stiffer than the blue but if someone can put me right?
.......and anyone know the part number?

Cheers

According to the manual the black spring 55421 = medium.

medium.... it's very precise....:rolleyes:

And idea what is similar to a Losi black front spring and a Losi pink rear ?.

Also can you get 3 hole x 1.2mm pistons or maybe blank pistons ?.

blank pistons yes! not sure on losi similarities, i'll check later

Hmm, no exact info but I thinkthe following is true:

Trf201 black is softer than trf511 blue.
Trf511 blue is I think slightly softer than associated blue
Trf511 rear yellow is slightly softer than associated silver

I've got a feeling there's a comparison chart somewhere on petitrc for the trf511 stuff actually?
