So you just purchased a new Mustang or BMW 335...a new sports car. You have upgraded your tires to the best
Bridgestone or
Michelin, and have your new wheels on order. Next stop...upgrading brakes!
Now there are some technical decisions to make. Solid, dripped, slotted, 2-piece, big brake kit...too many options. Let's tackle slotted/drilled versus solid first.
Do you drive aggressively? Check. Do you plan take the car auto crossing...check. Do you get to the road course...not planning to do that. If this describes you, a
solid rotor actually will be the best choice. Here are the physics behind that:
The more mass that you have the more quickly a rotor can disperse heat. This leads us in two directions. First it doesn't pay to turn rotors (takes away valuable mass) and second if you don't need slots and holes (drilled) your brakes will actually
cool faster!
Now if you are looking to run on the track and have successive high-speed stops, then
racing rotors are for you. The purpose of a drilled/slotted rotor was actually to dispel gasses that can build up with repeated hard hot laps from high speeds to low speeds. Not necessary for 99% of the road driving we do.
Now, there always is the aesthetic factor.
Drilled/slotted looks are different, and some people find that desirable. That's fine, it isn't going to be greatly detrimental to your stopping power, just remember it is not a performance upgrade as much as it is an aesthetic upgrade!

First, there was the Boxster. Then came the Cayenne. And now, Porsche enters the sedan market with the all-new Panamera. This luxury vehicle has all the bells and whistles, but you'll want to add just one more: aftermarket Porsche tires from
Tire Rack.
Consider Michelin auto tires. We picked
Michelin Pilot Sport PS2 tires for the Panamera shown here because they offer world-class dry road traction, handling and cornering capabilities. After all, a Porsche is meant to be driven. (Side note: these tires appear as Original Equipment on a number of performance sedans.)
But before you buy Michelin tires, you may wish to check out a complete
Tire & Wheel Package. For example, we paired the Max Performance Summer tires above with a set of
O.Z. Botticelli III wheels. A part of the
O.Z. Tuner System, they're custom-assembled for an impressive fit.
Build your
Tire & Wheel Package, or simply
search for Porsche tires. Whatever approach you take, aftermarket tire performance is yours for the driving.
