Any compound, Craggy tends to use M3's. Any insert allowed.
The rule is - Holeshots on driven axles, any proline tyre on non-driven axle..
We've done two meetings there - one bone dry and one slightly damp and 'tacky' we will do our upmost to run, the long range weather looks ok so far. We have big sheets which we can pull out and cover the track for any passing rain showers. The track has more grip when theres moisture in it.
Quality isn't great, but the surface here was kinda damp;
