Maybe so. It depends what you want and how you drive. The amount some people spend on mainly cosmetic "improvements" could also be considered a waste of money. Some of these changes such as wider tyres will actually reduce performance in terms of speed and acceleration and more than likely provide no more grip! And an extra 180 bhp will theoretically knock around 1 second off the 0-60 time But also remember that even if 2 cars have the same 0-60 time one can accelerate from standstill over a given distance quicker than the other, time to speed is not the same as time to distance. This is why you cannot rely on 0-60 times to say which car will out-drag another.
