the debate about weight in the trunk

[vanzuuk1]

If this is in the wrong thread then just move it, wasnt sure where it belongs.

I noticed in the jegs catalog they have a bladder you fill with water, it goes in the trunk and is a few hundred pounds. They say its for winter traction.This will be new to you california guys but northeasters put sand bags in their trunks for winter grip.

I know this helps put weight on the rear wheels and helps you get low speed traction in the snow, but doesnt it have a negative efect as the speed of the vehicle goes up?



Going around a corner doesnt the tail of the car have more weight pushing it towards the outside of the corner?

Under braking, isnt it just more weight that wants to stay in motion, even making the rear more likely to try and pass the front?

I am hoping for a scientific answer, not the " I do it and Ive never had a problem" response.
