Over the years many people who consider themselves a Porsche specialist have found that one of the most addictive elements of owning a Porsche are its maintenance and tuning upgrades. Year on year advances in technology mean improvements to old systems become available and new modifications are released to give many Porsche an improvement in looks, power, handling or ride.
With all these releases it can be a real head-scratcher for a Porsche specialist to decide which areas to focus on, which modifications give the biggest gains and what's popular for the over all look, sound and performance of your Porsche, the following is a list of some of the common areas that are upgraded.
Sander Kit
First up its upgrading your suspension, most agree that lowering a car gives it that little something, the sleeker looks of the car and the way it appears to hug the ground and corners are a sight of beauty. Tuning for performance by lowering is also a great option to help increase the cars handling.
Next up is the air intake. Air intake kits are a great way to get a little more power out of your engine along with an improvement in torque. If your have a turbo on the car the right kit will also help you out here by reducing the turbo lag.
Along with the air intake upgrade its worth looking at intercooler modifications which work great in combination with a turbo. Intercoolers are fairly specific to the car and the air intake modifications installed though so its worth doing your research, they work by cooling the air the runs through the intake to increase engine and turbo efficiency.
On the other end of the system you can look at exhaust upgrades. These can increase the overall performance by increasing the throttle responsiveness and by again reducing turbo lag. You need to be careful with your choice of exhaust upgrade though as the Porsche engines are delicately balanced so again research is the key here.
Finally, and some would say most importantly, are the brakes. Upgrading your brake pads is a fantastic way to improve performance, especially if you're taking your Porsche out on track days. The improve handling and allow you to break later on the track and make for better breaking during day to day use. Upgraded disc tend to come with improved cooling systems and better engineered, longer lasting, pads.
