I was thinking one day, about traction, and what ways there were to improve it without hindering high speed performance, or added weight. So, naturally, there are limited slips, traction control, etc. etc. But then, I began to think about a variable traction system. One that would create insane amounts of traction at a launch, and lessen it as speed increased (where tire spin is not a factor). So, here's the answer to my traction problem. It's a wheel, made out of some lightweight material, with tubes isnterted into it. Insides these tubes are lead (or some heavy/small weight) weights connected to a electronically controlled resistor. This is all confusing, I know, so refer to the attachment. As the ECU detects tire spin, it sends a signal to the risistors to lower the resistance pressure, hence, the weights will move outward toward the endge of the wheel. Centrifugal force makes it seem as though there is more weight on the wheel, hence more traction, without the downside of added weight. As tire spin lessens and goes away, the ECU again sends signals to the resistors when increase their resistance, and move the weights back toward the center of the wheel. So, you're losing all the downsides of adding weight to the edge of a wheel.
Problems,
-Weight of resistance is too much for a small electronic resistor to handle?
-Powering the resistance on a spinning wheel?
-Would it be beneficial?
-Cost issues?
So, if anyone else can throw out any issues you see with it, or could help me design this thing, I'll let you in on the money I get from selling this to Toyota .
