Could someone please explain to me what it changes when you raise or lower your lead when it comes to weight transfer. Thanks

I would like to hear more about this subject also. Here is my thinking, the higher the lead adds more rollover in the corner and puts more weight transferred to right rear. I keep my lead 16" to 20" from the ground. Low for tacky track, high for dryslick. Others please chime in. =01H

Most have read my thoughts on lead but my system demands this to work as planed! I use other factors in place of making it happen to let it happen naturally to be more controllable! Its kinda like being tripped!!! The faster you go or the quicker you turn you loose control of what's happening to greater forces making it roll more, steer more, and transfer differently!!! One one line perfect but with any other entry or speed, extremely unpredictable! I try to keep it low and hold left rear constant while the rest moves! No need to roll to plant if done by nosing just by lifting the throttle! Sure you need transfer of pounds , but it ain't happening if springs give or air pressure is letting the tire give! If correct no more than 1/2 inch roll out needed! Run the rear closed a bit and still drive around the turn with out getting all sideways or have so much drag of tire ratios down the straights!!! The lead in line with the cross is in the pivot line and just leans instead of having to be lifted to roll as only the right side reacts to stimuli! Lead moving can be a fix the same as any other adjustment but at what price elsewhere in true transfer getting things done correctly no mater what or where you run in at!!! It would be like tucking the right rear tire under to make it roll in stead of just letting it work elsewhere! Use limited roll for rear steer and transfer for steer and traction! Trying to run off the left rear-- you would have to be sideways to need it to straighten back up-- uf not -- the right side pulling will drive the car left nicely! Mine uses a gentle reversal of the crosses and drive wheel when nosed and rolled with the transfer doing the greater of the two by adding right drive instead of loosing left and needing more! Weight placement is always a key issue and the rule is tote as little as you can and put it where it does the most good-- that being LL&R for me! Low as not to make false motion-- left as to counter roll factors and rear for better rear traction and quicker transfer poundage in traction!

Without posting a bunch of babble, I'll try and give you a direct answer. Moving Weight up will tighten on entry,(works when track slows down and is slick, this will increase side bite) Moving weight Down will loosen up or decrease weight transfer (works on a heavy track) Moving weight up or down only changes how the car rolls. Moving weight Forward helps load the front tires more and decreases rear % (works on a heavy track). Moving weight Back, increases rear % and increases traction off the corner. Moving weight Left will loosen you up going in, (fast high banked tracks need more left weight). Moving weight Right tightens entry and middle (works on dry slick tracks)

The weight of fuel on top and falling as used has profound effects on some cars when the track slicks over and you don't slow down! I prefer my tank on the right down low as to tighten as the race goes and track slickens! It has paid off on the last lap for years! Too many factors involved with so many different chassis and spring combos in transfer of what moves and where! Best to think of it as G-force where ever it is while in motion! Roll centers and crosses that move or switch with speed is best controlled by other things than lead as the track changes constantly as does the lines you need to run to pass other cars! So I try to put it with the rest of a left running car -- LOW,LEFT AND REAR as to the rest of the entire chassis for the same reason-- TO WIN!!! Great question and wish I had a better answer but give us your problem and we all here will try to help!

It's just that weight shift is best given to the driver's control as with 4 wheel steer by better use of caster and spring combos! Getting to a balance of crosses in order to LET this to happen without the compromising weight sling for better control is a key factor! Having all my added weight close to the center pivot---( left rear wheel)--- and rear for faster, stronger transfer to that wheel --- hooks a bit harder on that wheel and I never want to roll up and loose that! Yes it takes much more right transfer to switch the cross if not well balanced in ratios and roll centers and moment centers to react accordingly but is most drivable to win on most any track! THE ONLY THING I MIGHT CHANGE BETWEEN RACES WOULD BE FROM SAUSAGE TO PORKCHOPS! THIS IS WHERE MY WEIGHT CHANGES! STILL A GREAT QUESTION!!! LL&R with out the sling and roll factors being compromised the next turn entry!

Three posts of Babble and you never directly answer the guys very specific question. Amazing! And you wonder why this forum is so dead! You even admit its your fault in another thread, but still you continue to post your babble. One simple post is all it takes to answer his question.
"Could someone please explain to me what it changes when you raise or lower your lead when it comes to weight transfer"
He didnt ask what you do on your setup. Maybe he wants to work on his own setup, Hello? Dont know why I even came back here. I'll leave again like everyone else, so you can continue to clog every thread with Babble!

If he had posted all his stats some one could give a more productive answer! Never seen weight work so different on so many but it does as with most any change! I could name 25-30 things affected -- some good some bad but here we go again! Put it where it does the least to hinder things that should be constant no matter what!!! I do!!! To many quick fixes with trick shocks and wheel spacers and over extended bars! Hey let us get a spindle upgrade too! That will solve all our problems! If it was that simple, I would put it all on the right up high and let it float down as my fuel does as the track changes!!! Oh wait -- now its taking rubber 10 laps down in the main! Post you answer and make us all thankful!!!

Could someone please explain to me what it changes when you raise or lower your lead when it comes to weight transfer. Thanks 4 posts of Babble Original question: did you read it? doesn't ask anything about what is right or wrong or when to do what, it was Simply "what does it do when it comes to weight transfer"? Went did set-up or stats change the laws of physics on what happens when it comes to raising/lowing leads effects on weight transfer?

When you changed any other part on your set up or went in the turn different or the track changed! This is why I try to put it away stable and constant! Babble indeed and I could talk on the subject for days to no end after 37 years of dealing with the same mind set we have been taught to believe! ---I deal with a lot of things that common sense sees as different-- such as shape of a piece of metal changing its weight if flipped over! Gravity is not at all as most think and even laws in history have changed in physics! The lead is not alone in this picture as in its physics! One pound more air in the right rear may react the same to get more transfer with out limiting recovery and may even help to recover faster! So I never do things that impedes others! As with playing with quick fixes that impedes mindsets!!! My answer revised is-- THINGS GOES SOUTH!!!

It just ain't that simple or is it too much so that you just don't get it! Last private post from last night by a guy crazy enough to give it a go replied AWESOME!!! -- Never been hooked so hard or handled so good !!! This is no game to me --- Just a bit of free help to those still willing to learn!!!
