I was very pleased to go to the Losi spring combo on my car. Faster? No. More consistent? Yes. You could push the car harder and it was more forgiving if it got upset. It will be faster in the long run when it is all tested as I get used to it.

I went #2 all the way around.
1/2" of rebound.
35 front with Losi silver.
27.5 rear with Losi pink.

I went ahead and got the GHEA collars and they fit very well.
We run on a track which has big car ruts and bumps. It soaks it up and holds the line much better with the new spring package.

Awesome upgrade.
