Weight placement to handle or just constant traction

I would have to say that most agree on need of traction of the left rear and look for ways to gain at this point! Keeping what you have consistently and varying the right rear would seem the way to go as most do now! I prefer to keep both all wheels planted at where they were set  with a minimal margin of change! Let the chassis move a bit less but free and easy on all wheels as to hold traction and steer ft. and rear! No track is ever the same for any car, lap to lap, line to line, speed to speed! Letting the chassis do its thing is what is best! Limiting or forcing has it's issues of transitions to deal with while allowing and helping gets you going faster! If not wanting to loose left rear, don't! Let the right side move, plant, and steer! If you want the right front to plant to turn, let it drop first with shock timing! If you want the left rear to pull you left when lifting, don't transfer that weight to the front but make it pull it down by having weight low left and rear! If you want it to react to different speeds or tracts in the turn, allow it to roll according to steer needed with nothing else affecting rear steer! A healthy rear percent helps traction problems and when pulling both front wheels, I would consider putting those horses to a better use in forward motion with higher gears to speed up the process of winning! Movements are greater anywhere but on the left rear with it weighted down! Lead and a tied string are both a good pivot point but not if holding or moving in the wrong spot! The holding of left rear traction compared to the car turning in the front or slinging in the rear depends on planting the right rear tire before you turn! Transfer of weight by pulling the nose down first sends it from right to left (if loaded) through the cross and plants the right rear as well as both front, before turning just by lifting! When turning with roll out working, more weight is added by the drag of the left not lifting! Little movement has taken place but transfer was improved by weight placement of low left and rear becoming the pivot point of the whole chassis! The extra weight has never slowed us down but has only improved traction and handling to go faster with less spin-out factors!
