That's weight bias. I think you get the idea why the tech side isn't as entertaining as picking on your neighbor with the STIFFYmobile. I'm still laughing!
P.S. WJM understood everything I typed!

Thanks I am trying to learn more about the chassie end of a car. That stuff is very interesting to me. Something new today Thanks Mike

I understand it and I want more. I have both hands raised. I'm an engineer with some experience with statics and dynamics. Technical talk gives me a stiffy. :)
Wedge out seems like it will lower the rear as compared to the front. How does that loosen the car? It seems it will lower and move the center of gravity toward the rear. This should result in less rear roll. This doesn't seems like it would make it loose?
There are so many variables and forces that I find it hard to determine the overall effect.
Thanks

As a good Robby fan you're take'n HUGE swings,when in reality it doesn't take much.First ,lets remember Na$craps rules.You have to meet minimum weight and minimum "right" side weight.Now have your way with the tunsten.Yes you can change wedge with static weight "placement"but wedge is more of a dynamic thing,preload applied to individual springs.Wedge is the weight percentage of the right front and left rear tire weights divid'd into the total weight.50% is equal weight of the diagnals.LTFR/RTRR-RTFR/LTRR.60% cross be 10% heavier RTFR/LTRR than equal.
COG would have little effect by adjusting rear wedge bolts ( again remember minimum and maximum Quarter panel height rules) COG would be more of a factor with the front of the car diving 3+ inches.
Where do you start,where do you stop? Did we talk about fuel burn off?
Do you watch Nascar Tech on Speed race weekends?

Does the 10% help load the RTRR. I have a lot to learn but this is cool.My friends always are asking why Cup Cars and not F!. Cup cars to me are just hanging on lap after lap. How do they do it, how do some go faster. Why is the car sideways down the straight, but planted sqaure in the turns. Its crazy stuff and I like it. Thanks Mike

ooooh fuel burn off my specialty... Did you know a Danica Patrick of Fuel weigh 100lbs.

13ish gallons of Sunoco GT unleaded or 2/3's of a fuel load= Danica,LOL
The 10% was an extreme.Less wedge puts more load on the LT FR/ RT RR.
The goal is to make all 4 tire work the same,temp wise,wear wise.( miracles can happen ). Oval track cars that use Detriot Lockers for a rear differential drive off the Left rear.
The appearance of being sideways down the straights,is YAW. this yaw is built into the rear end housing by toeing out the RT RR wheel and toeing in the LT/RR wheel.It's both a mechanical thing and aero thing. -

Exactly,thank you Slider.And the axis of the diagonal teeter-tooter is determined by the front to rear weight bias ( in racing this % is referred to as Rear% only)and the left side weight %.The closer to 50% cross the smaller the teeter-totter effect.

What did Frank Kerr say " Robby has more natural talent then anybody I know " Yep........That's why I watch Speedfactory.tv.......
