No.2 to No.3 pistons - oil change?

[kaszal]

Hello, I'm using the TRF buggy aeration dampers in a vintage Cat.

I have No.2 pistons 35wt oil in the front and No.4 30wt in the rear.

I want to change the front to No.3 to help it handle the small bumps better i.e. less "pack".

How much should I increase the oil weight to match the current feel e.g. +5wt or +10wt?



You can see the fronts are very laid down. I've had to use SX 4.5 rate springs to get the roll stiffness. The rears are Losi 2.5

Thanks for any advice
