Rear motor setup?

[gainsy]

Anyone used the 210 in rear motor format yet?
The reason i ask is i was running mid4 at stotfold on sunday, normally this is great round there, but as the temp dropped during the day the track became very damp & was like driving on ice, had schumacher greens all round & was still sliding all over the place
So i have decided to try the RM3 setup for the winter series next sunday as i have been told this will provide more grip & conditions look like they will be similar
Have had a look on the durango site setups but can't find 1 for RM3 or any infact for rear motor
Any advice much appreciated
