Starting out with a used up leaf spring car and getting up to speed is a learning that stays with you! Even if a winning car to start with! You have to protect your investment while on the track to be there the last lap to finish or win! Learning all the terms and meaning of them in relation to your car is like a strange language! Just trying to picture it all sitting still is one thing but in motion with forces applied it does become over-whelming in a hurry! Compressed heights of springs and pounds per wheel at locations with off-set leverage is best done in your head before applying it! Ride heights of leaning left on stock is best left to just looking at the angles of the tie-rods if not bent! Just picture them at level when rolled over in the turn for the correct ride spots! Much is as simple as this when setting up a chassis! Just think about what you want the car to do and how it will respond! Shocks are the same way as they determine timing of movement! The springs fight for position under load and transfer pounds accordingly! Compressed heights are the scale of holding within its range of movement before gaining or loosing poundage! If over compressed pounds go up quickly as to coil bind but if travel is coming off the spring it has to be compressed to start with or loose poundage with little movement and vice-versa! You can never have too much negative caster as this corrects pounds lost in the roll to help steer ft. and rear by changing wheel poundage in chassis twist at the spindle angles! A right turn should twist the chassis left! No stupid question on this site so please do ask away for we all are here to help!

Basic simplified thought is your best friend! If you took your street car and let the air pressure down very low on the left side, what would it look like on the scales? Did leaning it more left add pounds to the left side? Will it now have better left rear and be harder to roll right? Does the springs on the left now have more preload and travel with out loosing traction? Does the right steer bar have a greater angle than the left? Do you have roll out by radius from the center axle? Would adding a driver and a few pounds in the left rear of the trunk add traction to match the right bar thrust angle while taking the load off the right ft. to nose easier? Would all your ft. end settings now be close to correct? Add a few offsets and roll out to this mix of variations and your around the corner faster than most trying harder! Once understanding takes over in handling, its a Sunday drive when the car wants to go left all the time with out the need of adding steer!

When just learning the ropes they sometimes become braided steel cables with pulleys and hooks that entangles the masses! It may come a little more clear by keeping it simple and putting forth the effort to learn one thing and how it effects another before picking your next target! Just learning all the terms related first helps! Some are the same depending on topic and others are general to related variations from side to side! The thing is to open up and ask all you need until you get the answer you understand! We all need answers and questions is the best way to promote understanding! My answers are sometimes complicated but most just complain instead of helping me correct my ignorance! Those who put forth the effort in one to one messaging have been impressed by being faster or winning! Ask all you need to get what you want to know!!!

A rope has two ends to it, one maybe frayed and need to be tied in a knot to keep it from more damage or looping around! The other can be wrapped tightly and stiffened by other means! The corners of a cars chassis is the same way! While I tie my left rear to keep it from looping with left rear pounds and lead, the front is free to move in any direction of steer by pivoting off of the left rear! It can nose, roll the right rear down or pull the front up but the left rear stays constant as possible by the lead holding it there! Getting pounds from some other place rather than loosing them on that wheel! Transfer of weight by the load shifting through the cross gives instant planting of the right rear when lifting the throttle! Gaining right rear pounds to a close equal of the left without loosing any there took me a while but this bit of frayed rope is what tied our car in the turns to be faster and stay hooked up to win so much! You gain pounds and balance but loose left rear only as a increase in the balance of power occurs by adding right rear pounds! ANY QUESTIONS? --There should be!!!

How can you send pounds to the right rear when braking, nosing, and before the roll? All the weight heads to the unloaded stronger rt. ft. spring! The chassis is leaned left to start with making this corner higher to have plenty of nosing room with out bottoming out or having to roll very hard! As the spring gives down, it puts more weight on the left ft. spring that is weaker and already preloaded! It cannot move much before coil bind steps in causing it to be stiffer or stronger! This stopping motion places the weight across the left ft. to the right rear. And sense the left rear is tied down with lead it never raised but rather pivoted at the tire and the lift you see at the rear bumper is only leverage at work trying to lift the lead while actually adding left rear as the right rear gets more to hold it at a level of control of left rear and traction! Picture this chassis with no body, engine, or rt. ft. wheel! The lead needs low, rear, and left to help hold left rear when just sitting on 3 wheels! It will pivot down with one finger at the rt. ft. while adding weight to the lt. ft., then right cross until the point of moving the lead up! Once something moves, it looses it usefulness in holding any more than it could! Adding 150 lbs. to the left rear of any chassis only improved it if using it for the good of holding left rear!
