Solid and vented rotors made with gray cast iron are the most common types of rotors. Drilled and slotted rotors are a variation of the same design. A solid brake rotor is just that – solid. There is no space between the two friction surfaces. A vented brake rotor more commonly has a space between the two friction surfaces of the rotor. This helps with cooling and is more common on the front of the vehicle because front brakes do 70-80% of the braking and endure the most heat.

Unlike slotted or drilled faced rotors, general stock replacement rotors are normally solid faced rotors that are either solid or vented. When replacing a rotor, there should be little confusion as to whether you need a vented rotor or not. If your car came with a vented brake rotor, then the replacement part will be a vented brake rotor. If the car came with a solid brake rotor, the replacement part is a solid brake rotor. No solid rotor replacements are available for a vehicle that came originally equipped with a vented rotor.

Slotted and drilled rotors are a performance modification that do not increase braking power, but might aid in the cooling of the rotors in high heat situations. There are both advantages and disadvantages to having slotted or drilled rotors. One rule of thumb is that if you are just daily driving, there is no reason to get slotted or drilled rotors other than to improve the way your rotors and wheels look. (Drilled and slotted rotors can have an aesthetic appeal to them because they may have a rust prevention measure applied to them and can be indicative of a performance braking system.) One disadvantage of drilled rotors is that they will provide more friction against your pads and reduce the life of them. Another disadvantage is the potential for a drilled brake rotor to crack when subjected to thermal stress. A drilled hole can upset the grain structure of the metal; the result is an uneven temper in the metal. As the brake rotor cools, the uneven temper can cause cracks. The most common crack seen is located from the outer most drilled hole to the edge of the brake rotor. Since the edge of the brake rotor is the first to cool, this is where the most uneven area of cooling occurs. For this reason, drilled rotors are not well suited to racing conditions in which high brake component temperatures are always occurring. Cracks cause vibrations and the larger the crack the more dangerous. The advantages are that the scrub friction of the holes and slots, while increasing the wear on your pad, reduce the chance of the pads becoming glazed.

Slotted and drilled rotors have a series of slotted channels, drilled holes, or both. These rotors primary purpose is to reduce the effects of brake fade. When the temperature is too hot for the pad and rotor to work properly together, brake fade occurs, which refers to the reduced feeling of brake power. The high temperature causes the brake pads and rotors to release a gas, thus reducing the friction that they would provide at lower temperatures. The slots and drilled holes are a means to dissipate this gas and reduce brake fade. The drilled rotors may even help cool the braking system; however, the drilled holes may encourage the temperature related fractures previously mentioned. Of course, when you are experiencing brake fade, you are punishing your rotors to the point that you could warp or crack them regardless of whether or not they are slotted or drilled.

Small, efficient, smart and bright colored cars are the trend for 2010 in the automotive market. Automakers are focusing on small cars and as new models surge into the market, bright colors will blossom. Since car manufacturers are focusing on the small car line up, therefore to given them a jazzy and fiery appeal, bright colors are the order of the day. The experts also feel that if bright colors are put in large cars, it will be a little too much for the consumers; hence these colors are best suited for the small cars. When it comes to cars, colors matter a lot because it represents the personality of the person driving that car.

When the buyer visits any showroom, the first thing that attracts him is the color of the car and this is one of the main selling points of the car. The car aficionado feel that colors can bring the customers out of their recession-dull mood, therefore colors carry a lot of weight when it comes to make a purchase decision. People are now tried of black and grey and look for more vibrant colors in small cars like Chevrolet, A-Star, Hyundai i10 and many such names. The automotive color spectrum has been monotonous for many decades with only few colors hitting the car market including black, white and grey. Now even the eyes need a breather and for that vibrancy in looks can play a crucial role.

Jazzy and peppy colors are in these days as small cars represent the same. The new entrant in the small car segment, Maruti Suzuki A- Star is available in vibrant and peppy colors like bright red, paradise blue, sunlight copper, healing green, silky silver, desert brown, azure great, midnight black and arctic white. Why get a grey or white car when you can cruise in sunlight copper or electric blue instead? Dull and monotonous colors will not suit the small and zippy cars which are targeted at the youth. Let black, grey and white enhance the elegance, sophistication and exclusivity of the large or big cars. Small and vibrant is what people look for in todays time because of prices touching sky everywhere.

Reds, lime greens, orange, electric blue are in vogue in small car segment and this has increased the demand of thee cars among the youth. The color one chooses foe his small car is dictated by career choice, personality and popularity. For most of the people, car is more than just a utility item; therefore a lot of stress is there on the colors like yellow, green, red, blue, beige and white.
