Woodcoat, thank you for the run, notes and congratulations to the front runners.   I think the USA builders would love to know a few secrets to building over the bumps cars.   Good luck to all the builders next round.

@Mike174. Don’t forget Team Brumos RSR is leading in deslots with the BMW M1.

For Rally track cars my main advice would be:
1) Short wheelbase cars preferably (short & wide)
2) Keep the Motor rpm medium to low (easy for the drivers to manipulate the cars around the tight bends and bumpy or hilly tracks). Normally within the 18-23k rpm range, unless your adding 4WD then 25k rpm maybe necessary.
3) Spring guide suspension is very necessary.
4) Motor mount or rear axle suspension works better than without.
5) More ballast than you would usually use on a flat track surface.
6) Loose front axle helps to stabilise the cars around the uneven cambers of the track.
