According to an article in Race tech magazine overall load transfer depends only on CG heigth and the width of the car's track. Dampers, springs and geometry only controls how the load transfer varies from front to rear and also how it varies as the car passes through the entry, apex and exit of the corner.
It also states that load transfer is bad for grip.
that last sentence is a massive contradiction!
lowering roll center puts more load on that wheel by the car rolling more.
trust me this is what happens.

Atheena,

What you said is correct up until the last sentence.
CG height is dynamic, it changes with suspension movement. Your correct, how much it changes depends on the RC, Shocks, Springs, droop etc. Load transfer is not a bad thing. You can adjust it to find traction, or even out tire wear. Too much, and yes, it is bad, so most seek to find a nice balance.

R/C racers don't usually adjust for CG, it changes too much. That and most race-oriented cars have their heaviest items low and fixed on the chassis for a low CG. That is why we play with RC and other suspension adjustments. To change CG, you would probably have to add/move weight around/higher on your chassis.

And with that, i'm off to the track to adjust my RC on the PRO4, at the SOCAL RCWY.

but we can change c of g by lowering or riasing the car.

Correct, but how often do you change your ride height? Most racers I know usually run the same ride heights, from 4mm to 5mm for touring sedan. You see more racers adjusting RC/Shocks/Droop, etc, then adjusting ride height to play with CG.

Yes i agree that ride height is usally the last thing adjusted but its one of the first for me if the track is wet or slippery.
its all about getting a balance bt grip and stabillity.
but ive already stated what effects what above and its all true.even with the ride height.
