XB4 '16 / '17 setup for stotfold and Tyree choice

[Kelk]

Hi guys

Running the 4wd regional series for the first time this year and need some help

I usually run on a flat Astro surface with good jumps etc at SHRCCC but this weekend I'm at stotfold which is good and bumpy. I've looked at petit RC but I wondered if anyone had any recommendations for springs and oils?

Anyone have a stotfold setup?

Additionally - anyone run their X-ray on darts at the rear? What experiences do you have and what front tyres did you compliment them with?

Thanks
