Proper tuning not only focuses on more power and speed. A properly functioning brake system is extremely important. Do you brake a lot and hard on a regular basis? Then do not hesitate in upgrading your brake system.
The braking power will increase which will create resistance faster. Not only will you have more powerful brakes, but braking is also safer. A brake system does more than just reduce your speed. A good brake system not only makes sure that you can drive at higher speeds for longer, but also that you can accelerate faster after braking, thus making it certainly worth the investment.
