Could anybody tell me what TRF springs should i have using in F1?
In fact i am using red spring.

How much watt of silicone oil will you guys put in the main damper, please?
I put Trinity 20WT oil in my TRF damper.

And how much watt of silicone oil will you guys put in the rolling damper, please?
I guess it should be so much thicker oil, maybe 40 or 50 WT oil, isn't it?
