Lr wheel

[Mason5]

Can someone explain when running a 2in wheel on the lr then changeing to a 3in wheel will loosen the car. Does this just change this on entry or threw the corner. thanks

When you tuck the LR under the car whether you increase the offset or remove a wheel spacer you are essentially moving the center of gravity to the left. You would see a small increase in the LR wheel weight which make you think the car would be tighter coming out of the corner. But the extra left side weight means the LR tire has more weight to push and the RR has less weight to push thus the rear kicks out making the car loose. Typically you would add a small amount of wedge when moving the COG to the left to keep the change neutral.

Braking would have the opposite effect.

This is a crude way of looking at it, but gives you a general idea of some things tha happen (like what wheelspinner discribed).

The old shopping cart: say the rear tires are 3 feet apart

Let assume that both rear tires have the same wieght on them (easier for now) so since both rear tire should have the same traction the driving force is exactly between the tow rear tires (half way between them).

If you kick the cart right there (1.5 feet from the LR or RR tire) the cart should go pretty straight forward.

Now say you move the Left rear wheel 3 feet to the left, now the center of the rear tires is 1.5 feet farther to the left then the original point. If you kick the cart at this point the car with go to the right (tightening on the gas). Now do the same by having the cart rolling and stop the cart at that point, the cart will try to go left.

This is all asumming that the rear tire mantain the same weight on each tire, which wouldn't happen in this case unless you adjusted for it.

It is crude but you should give you an idea behind the principle.
