Always keep in mind that you may be going the correct way, but there could be an adjustment elsewhere that may be masking your initial change. When you push an object like this across the floor you'll notice that the wheels will swivel back allowing you to push forward with ease. Tire pressure is yet another adjustment that will aid you in achieving the best possible grip. Chassis will feel tight while cornering. You might want to adjust the chassis elsewhere to tighten the car up on entry. Stiffer LF will make the car loose.
So how do you know when you have the correct amount of front brake bias? Perhaps a track bar or tire pressure adjustment would be the way to go when pitting after so many laps. The front brake callipers are pretty fool-proof but never-the-less do require attention from time to time. Stiffer RF will make the car tight. The softer the REAR shocks, lower the number the tighter the car will be under acceleration.
A larger rear sway bar will actually loosen the car up due to the fact that the way the weight is being transferred at the rear, is just the opposite of the the way the weight gets transferred at the front of the vehicle. You'll notice that when making a spring change either stiffer or weaker, it will have the same effect on the chassis as it's diagonal opposite corner. It should be remembered that it is not possible to damage the dogs when fully engaged in gear. The inline booster on post '76 models is easily removed for servicing without having to upset the diaphragm area. I may increase the front sway bar some if the car is a little too loose.
You might think that by changing wedge you would change left side or front bias, but that isn't the case. Did you go faster after making the spring change? If the rear end moves in the least, undo each step completed, and start back at step 7. Dirt Track Chassis Setup at the rear for Cornering. Will cause car to pull to the left. My experience has shown that on most drums the centre hole does NOT run true with the locating spigot onto the rear hub. This system is almost as good as an automated one as long as the driver pulls the lever very quickly.
