Stick with the spring that performs best for you .

We are using slicks at the moment @TRCR and even with the grip slicks bring I had better traction with the standard yellow spring .
Sometimes the truck would step out of the turn just a little and add time to the lap using white ft.

Also the roll was way less with the white ft, good for the sweeper & higher speed turns , but bad for sharp turns on the infield as you get a bit less steering .


If I were you ?

Try the yellows again & compare the times .

That's what I did and discovered the spring that was faster for me ...
