    Once again... Already answered that.... If you enter off the throttle then yes your entry will be tighter with less wedge.... I've yet to see an explanation from you on your weight distribution theories!? You just keep asking the same questions in different ways... Questions I've already addressed... I'm ready to hear your debate.... Not your fog of repetitive manor questions. If you are as wise as you portray yourself to be... This should be a simple subject for you to grasp.... And if I am wrong here please explain why. I like to learn

      It all depends on how people think a car is tight. too much cross or too stiff of springs in the right front will make a tight car, a lower right front will make the left front get more weight and help turn the car. A lower right front spring will make less cross dynamically , will make the front tighter and rear looser.

        This is exactly right. Now the reason I ask questions is because it get YOU more involved. The classes I hold if I only talked at you and did not ask YOU to answer a question you would not be involved and learn as well. So I also have the drivers, crew members, and others try to answer as many questions themselves. This is a trick in the teaching world to have a student adapt and learn making it more fun and more involved. Now the big change I have seen in the dirt track world hit us in the mid 2000s. We had a birdcage epidemic that hit everyone and all were jumping on board by 2007-2008. The problem most were having is the spring packages used. Most have had a heavy rf spring in the car since the beginning of dirt track racing. This rf spring made the car act like a pivot point on the chassis instead of a turning tire. A turning tire is a tire that actually controls where the car is going to go and not a tire to just plant into the ground and pivot off of. Reason this trend was big was because it trickled down from asphalt drivers. This heavy rf set works but strictly on point and shoot track that are tacky and or dry. Tacky you will be vey fast and dry you must watch rr tire pressure due to the 50 degree change we usually se differnet from lr. the growth of 50 degrees is at least 5 more psi and this will start causing a loose condition over time. I see many of these drivers with this set up and at lap 5-6 is when the air expansion in tire reaches a point in which it ballons. Most cars after 5-6 laps lose a minimum of .500 second immediately. I went into a few details as to what a heavy rf will do. Ultimately we want the lightest possible spring on the cars for strictly ballast weight transfer. A scale says what a car is at a stand still. Once put into motion we need more weight of the car to transfer to the right side of chassis. This is where a chassis dyno has shown percentages and what the car is doing. Much like the NASCAR chassis dyno you've seen we do this on dirt as well. It works diffently though but shows percentages on the car at corner entry, hike, mid corner, and exit. Going back to the heavy rf spring youll notice the other trend was to have MORE rear brake to crutch the car and turn it therefore sliding the rear tires more and causing an unpredictable situation and after 3-5 laps you will feel the car coming out from under you. Weight in motion is what most have not understood and should start understanding more. I could go on for pages on this subject. In fact 3 day classes are not enough because of the amount of information you need to take in. Now as for a longer lr bar we do this to compensate for the softer rf spring. We compress the rf spring more by having an overall higher hike to achieve the cross desired. This is where a chassis not designed for a lighter spring can be spotted. You simply look at mounting of the lr spring slider. If it isn't set in the chassis correct the car will be unloading the spring because you cannot index it properly lets say with a 17" long upper left bar. For example if you had a 700 rf spring youre going to compress it lets say 3" in the car. Well ever 1/16th of an inch compressed is 43.75 lbs while a 550 spring is 34.37 pound for every 1/16th inch traveled. In a classroom I have a model to show this affect and actual weight placed onto each tire. You can make a scale say what you want but in motion is it what you want?..

          What 3 day class do you teach? I am planning to attend one and I want to ensure I don't go to yours, you type in circles but say nothing for the most part.

            Please post up a picture of the rear of your car or front.

              I couldn't agree more with stock car driver. You spent all that time typing up that lengthy message but yet again failed to provide any factual or argumentall information on your weight distribution and spring change theories. You're nothing more than another 4m troll ruining this website. I've had my feel of this bull.....

                Just tell me what 3 day class you teach so I can be sure to AVOID it.

                  You can only help the ones who ask and are open minded. Im sorry you both use a 78/21/1 ratio on all four. Welcome to Cup level boys.Also please post up rear pics of your cars. Thank you. We can change 3 things the second you do so and youll understand. This is very basic.

                    Post up pics of which class you teach so that I may help you get rich quick with my day trading plan as well as ensure you know how to fry eggs with a white spatula or black your choice but one is better than the other do you know. post pics and ill let you in on the secret....

                    pm if you have a green spatula. thank you

                      When choosing the chassis you have in your coral why did you pick them? I think I may be right saying you do not use lower a arm offset bushings, the brackets on your chassis are not degree to length matvhed for scaling purposes/indexing, you run a spring pull bar or only 2 bushings in it while still running a 90-10 with a bisquit set up. In which you tend to forget bushings do not store as much energy as a spring pull bar. Shall I go on? After all your car is for sale.

                        Can you imagine if this guy and Dynoman joined forces. They would be the best racing team in the world. LOL
