Hi Matt,
The attached is Chris's (Delves) latest set up that he ran at the last round of the Maritime Off Road Wars - an indoor circuit with medium grip on carpet plus slippery wooden sections.
Not quite sure how grippy that will compare to your ozite carpet. In higher bite situations, we'd probably look to up the spring rates a touch - going to a blue on the front and a pink at the rear to keep things plantedor maybe up the damping a touch.
On really high bite, if you can hang on to it, the 2mm standard axles can be used to sharpen up the steering response but I'd say have a try with the attached and go from there.
It might not work for you but hit us back with what's going on and we'll throw in some suggestions if you like? Like we'd always say, the set ups evolve for each driver - if the attached helps as a starting point then that's great but don't be afraid to try out your own things, one at a time, and see/feel what they do. The 22 is very rewarding in this respect - it does tell you what's going on if you want to listen
HTH
