Wet Astro set up for C4.1

[ejw]

Evening All

New to racing so have limited know-how when it comes to set up etc, raced Sunday at Stotfold (Astro) and decided to start with the below/attached set up (Paul Bradbry Tallywain) in the hope that the astro would be at least similar in grip level etc.



Sunday turned out to be a fairly wet start to the day and i arrived to a difficult track where one corner would provide reasonable grip followed by another that was like ice causing a spin out if any hint of power was put down and huge understeer if i tried to turn in off power.

Started on Yellow Minispikes and using Green Minispikes seemed to aid very little and a fun but very frustrating day was had. Can anyone provide any insight into best things to start with in terms of looking for more all round grip, even general non Centro specific advice would be appreciated, when things are more slippy than anticipated where do you start?

Please Help!!!
