.. after stripping the car of unnecessary things like radio,
aircon, trims, lady-mirror, spare-tyre and using lightweight
wheels..
why ruin all that by making it work for extra load?
Now that you've got less weight to hump about, take
advantage of it and downgrade your tires to suit your
new vehicle weight.
best part is, you actually get more power, and it
takes less fuel to do powerslides. And if people are
too scared to be passengers - well that's their problem.
never needed that deadweight anyway...
