Setup for thick Astroturf
 

The heading says it already, I need a good setup for my 4-gear X6 for our Astroturf track. Already been looking in the setup corner but didn't find something for me. The track is rather large, has a 30-40m long straight, some tables and jumps and two 1,5m high steep turns and has plenty of grip.
Motor is a LRP X12 5,5 Turns, with the damper oil I started at 35 at the front and 30 at the back, tires are Schumacher Minipin yellow at front and rear.

Stotfold & Silverstone are Astroturf, not 'thick' astro tho, so try using these as a start point, tyres at Stotfold have been yellow spikes (worn ok) rears & staggered ribs on front. May have to cut a row of spikes from the outside of tyre to reduce griproll.
