Change in weight distribution question

Hey guys,
Was out running errands and I noticed a change in the handling with my 997s. Here is the scenario. Went by my local wine shop and picked up two cases of assorted wine. I placed it into the front boot and drove off. I noticed the oversteer had decreased somewhat when compared to no weight in the front. Now, that would make sense putting more weight on the front, but that got me thinking. Do any of you track guys redistribute weight to the front of the vehicle and if you do, what are your methods. BTW, I thought if I rear ended someone it would be really messy with all of the wine in the front boot. Thanks in advance.

A few years ago some track novice drivers had a bag of sand in the front of there car. When the instructor found out about it they made an announcement to not have any sand in the front of your car. They said if the Porsche engineers thought more weight in the front of the car, they would have. I have not tried it but I will say that when I lowered my 997, I found the front end was more planted, perhpas your extra weight produced the same results.

Great point NorthVann and if that is the case then I can see why people lower their P-cars and use the aero kits/ GT3 kit. Thanks for the info.

DPorcella@sbcgl is infamous around these parts
If I remember correctly, some older aircooled 911s had two batteries, one roughly at each front corner. I've always assumed the current model has the 50-lb battery in front for weight distribution reasons. I'm not an electrical engineer, but I know it doesn't make much sense to run voltage that distance from the front boot to the starter without an overriding reason like weight distribution.

"The voltage drop of any insulated cable is dependent upon the route length under consideration, the required current rating (in amperes) and the relevant total impedance per unit length of the cable. For cables operating under dc conditions, the appropriate voltage drops may be calculated using the formula:

2 x route length x current x resistance x 10¯³."
