Re: Is a 50/50 weight split really ideal? (Sharpix)
quote:[HR][/HR]It's not weight distribution the only thing that matters!
There's something more than 50/50 weight distribution, is how the weight is distributed vertically, an example: The car is 50/50 balanced but the weight at the front side, the mass center is 50 cm higher than the rear one, relative to the road. Im pretty sure this is something that has to be taken in consideration, too, but im not sure how.
Someone explain this, pleaseeeeeeeee!
There aren't two separate masses (front and rear) that you're dealing with. The car is one mass with one center of gravity. The car's mass acts like it's all at the center of gravity. If the center of gravity is halfway between the front and rear wheels, there's 50/50 weight distribution.
The center of gravity (center of mass) actually has a height too, as you've pointed out. Suspensions have a roll center. It's a theoretical point around which the car rolls (leans). With some suspension designs, the roll center moves around depending on whether the suspension is deflected (from brake dive, squat from acceleration, or as the car tilts in a corner). If you draw a line through the roll center of the front suspenson and the roll center for the rear suspension, that's the axis around which the car body rolls. The height of the center of mass to this roll axis indicates how sensitive the car is to roll and it gives an idea of how it transfers load as the car corners.
So, yes the height of the center of mass has an affect on handling, but, it's also tied into suspension design. The higher the center of mass, the more the outer tires have to work in a corner. For the same center of mass, suspension design can affect how evenly the load transfer is distributed between the outer tires. If one tire is working much harder than the other, it's going to limit the cornering capability.
