Not being grouchy in reply, but I disagree with the 'only fine tuning' comment with tire pressures. Set a Legends Car on the scales with 20 pounds of air in all the tires. Let 10 pounds out of the rears only and watch the numbers change. Same amounts as a spring change would yield or adjusting air presuures enough to change the rake of a chassis. Another view is that by letting air out if the tires, you change the compression or rebound effect on that corner of the car as would a shock valving change. The biggest thing to overcome on these cars is their design, which is that have a built in push. The recommended 2007 set-up for dirt still has a push. Want a base set-up for a starting point ? Install 200 pound springs all around, lay the caster back on both sides about 3 or 4 degrees, 4 degrees of camber leaned in at the top of the front tire on the right side and 2 degrees leaned out on the left side (for oval racing). Toe the front wheels out about 1/8". Square the rear end, set your ride heights the same all the way around. Go out and run some laps and kind of easy, not pushing it hard, then go out for a few more laps and run it as hard as you can. See which driving style that you prefer and make adjustments to the chassis from there. Biggest problem with trying to suggest a base set-up for someone that you never met is that you do not know their driving style. Once they have driven a few different set-ups, then it is easier to give them a base set-up. The reason I suggested what I did above for a base is because someone could be reading this that has never driven a Legends Car or any race car before and don't know their characteristics to begin with. Another reader could have experience with other chassis and decide to get to know these chassis. To get to know your driving style and reaction of these cars you have to set one up neutral and let the driver get the feel of the set-up neutral with change of driving style and go from there.
Honestly, when someone contacts me for a set-up, first thing I will ask is their spring set-up. Once known,I will generally advise adjustments with those springs that they are used to. Goes back to how they are used to the car reacting. Let them run the chassis that way and learn from the change. Once they report back to me how the chassis reacted,I can identify their driving style and move them in the right direction from there. In the past I have given racers kick butt set-ups and they couldn't drive it because of their style. Hence, once again why I have not blown a good base setup out there on this thread. There is no base established until driver ability is known.
At this point, I will ask if anyone even knows how they built the push into these chassis
