I was looking for some springs for my Bmax2.
After looking at the springchart on Petit RC
CLICK
I decided to try 2 sets of YATABE springs. Yellow front and Green rear.
I thought the Yatabe springs would all be harder than the Yokomo ones and extended the Yokomo spring range.
Once out of the pakkage the Yatabe springs didn't feel as hard as i thought they would be. So i mounted them up on the car and found the same.
This is what i "feel".
Rear: standard blue spring is harder than Yatabe green. (also have a set of Yokomo Purple and they are way harder than the Yokomo Blue)
Front: standard blue spring is close to Yatabe Yellow. not a big differance but seems to be harder.
Yokomo orange is harder than de Yatabe yellow (and Yokomo blue).
Also mounted up the rear springs and measured the sag.
Yatabe Yellow is softer than yokomo blue (and Purple)
So now it seems the Yatabe springs dont extend the Yokomo spring serie.
And the spring rates in the Sprinschart seem to be way off!
I wish Yokomo and Yatabe would give us a rating on the springs.
