If your planning to modify your Porsche for performance or how it looks then its best to ensure that all the new parts provide a weight saving opportunity to maximise speed and handling potential. In fact many Porsche modifiers inadvertently often add in extra weight when modifying, this is especially evident when larger intercoolers, spoilers and in-car entertainment components are fitted.
If you can remove 70kg of mass from your car you will effectively provide yourself with better handling and a theoretical 7HP gain through a reduction of inertia.
People often miss understand the concept of weight. Weight is the measure of the earth's gravitational pull on an object. Mass is a measure of the amount of matter in an object. Put our Porsches on the moon and its weight changes; it's mass however does not. Inertia is a measure of an object's resistance to a change in direction or acceleration; mass affects inertia, weight does not, though the distinction matters little when racing on planet earth. However, the more mass, the more inertia--and the more inertia, the more the resistance to acceleration, and the reduction in the performance of your Porsche.
Having a quick look at science we find that the effect of inertia on your Porsche is therefore your worst enemy at speed. The tendency of your Porsche is to resist changes under acceleration, braking and cornering whilst in a state of motion, this is inertia and its effects can be reduced in a vehicle through its weight and therefore mass as already discussed.
It is by this basic understanding that Porsche weight reduction is identified as an important part in improving both handling and overall speed.
Here are a few straight forward things that can easily be replaced or removed and can offer some immediate gains:
you've removed a lot of weight from your Porsche. What gains can you expect to see. Well, removing weight and therefore mass from your Porsche will improve overall performance of the car in three main areas:
Before you go on a weight/mass reduction programme, 'where' you remove the weight is more important than the 'total' weight removed. A few kilo's removed from the ends of your Porsche are going to be more noticeably beneficial than a few Kilo's from the Center of Mass. The hierarchy of importance of weight reduction goes something like this:
If you own a Porsche 911 then approximately 60% of the cars mass it at the rear of the car. So removing or lightening the front in isolation will ultimately adversely effect handling performance. In this case removing weight from the rear will be the optimal course of action.
This has been a general over view of some of the considerations for improving performance with weight loss. Inevitably there will be other considerations, but one thing is for certain: Putting you Porsche is on a diet is definitely a case of 'Less is More'.
