Basically i want to get the outmost for a tight bumby track with not to much grip.
Also what about the upstop??
Thanks very much
Bumpy tracks are relative to the individual, but lets say it is truly bumpy and you are running 6+mm of ride height to get around without burning a chassis per run.
More downtravel will allow the car to feel more controlled over the bumps because the tires will follow them instead of skip over them. Up stops are really just there to limit how hard the chassis hits so you can place them close to where the chassis bottoms out. You can adjust the shocks bottoming with the shock end lengths too (there are 3-4 plus different bottom shock retainers)
More rear downtravel will allow you to have more roll in the car and have the rear wheels still touching the ground, with less you have the risk of one raising and causing you to spin because the weight is toward the front of the car in most corners.
More front downtravel will allow the front suspension to work a bit under acceleration through the bumps and give you some steering while the weight is on the back of the car.
Front up travel can be limited to stop the amount of weight transferred to the back of the car during acceleration (think drag racing, front wheels off the ground puts 100% of the weight on the rear tires but no steering)
