BMW Users

BMW is one of the gratest cars for drivers who liek to drive agresively… BMW have a sport line and a great driving performances… but if you do some make up or tune on your bmw… it can look like these beauties…
Car tuning is both an industry and a hobby, in which an automobile, motor bike, scooter or moped is modified in order to improve its performance, handling and presentation and improve the owner’s driving style. As most vehicles leave the factory set up for average driver expectations and average conditions, tuning has become a way to personalize the characteristics of the vehicle to the owner’s preference. For example, they may be altered to provide better fuel economy, produce more power at high RPM or the ride comfort may be sacrificed to provide better handling.
Car tuning is related to auto racing, although most performance cars never compete. Rather they are built for the pleasure of owning and driving such a vehicle. Another major facet of tuning includes performance modification to the car exterior. This includes changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, adding spoilers, splitters, air vents and light weight wheels.

Audio

Is a term used to describe the sound or video system fitted in the vehicle. A stock audio system refers to one that was specified by the manufacturer when the vehicle was built. A custom audio installation can involve anything from the upgrade of the radio to a full-blown customization based around the audio equipment. Events are held where entrants compete for the loudest, highest quality reception or most innovative sound systems.

Interior tuning

Interior tuning is a term used for modifying of the interior of a car. for example; removing the back seats to make room for a sound system, or taking out the front seats and replacing them with racing seats – commonly known as bucket seats.
Another recent form of interior tuning is the replacement of the OEM Shift Knob with an aftermarket version such as a weighted shift knob for cosmetic and/or for performance purposes.

Engine tuning

Engine tuning as of lately has been marketed as the replacement of basic engine components with aftermarket versions that perform the same functions as those replaced while promising an increase in power output. Car tuners usually install new turbochargers, modify the car’s engine cooling unit, and replace the air filters; but they could also install a more powerful engine on the cars they modify.
For example a tuner could modify the engine control unit to gain more power. Another example is the modification and/or replacement of the OEM manual transmission stick shift (also known as a gear stick) with an optimized aftermarket design known as a short shifter. For further “fine” tuning, the driver could fit a Weighted Gear Knob.

Suspension tuning

Suspension tuning involves modifying the springs, shock absorbers, swaybars, and other related components of a vehicle. Shorter springs offer greater stiffness, a lower center of gravity, and a lowered look. Stiffer shock absorbers improve the dynamic weight shifting during cornering and normally have shorter internals to stop them from bottoming out when shorter springs are used. Stiffer sway bars reduce body roll during cornering, thus improving the grip that the inside tires have on the surface; this improves handling response. Other components that are sometimes added are strut bars, which improve the body stiffness and help better maintain the proper suspension geometry during cornering. On some cars certain braces, anti-roll bars, etc., can be retrofitted to lower-spec cars from sports models.
For offroad vehicles, the emphasis is on lengthening the suspension travel and larger tires to increase ground clearance.
Lowriders with hydraulic/pneumatic suspensions use another unique kind of suspension tuning in which the height of each individual wheel can be rapidly adjusted by system of rams, even to the extent that it is possible to “bounce” the wheels completely clear of the ground.

Body tuning

Body tuning involves adding or modifying spoilers and a body kit. Sometimes this is done to improve the aerodynamic performance of a vehicle, as in the case of some wings or bumper canards, or, to lighten the vehicle through replacing bodywork components such as hoods and rear view mirrors with components made from lighter composites such as CFRP. Cornering speeds and adhesion can be improved through the generation of downforce.
More often however, these modifications are done mainly to improve a vehicle’s appearance, as in the case of non-functioning scoops, spoilers, wide arches or any aesthetic modification which offers no benefit to performance. Very rarely does an after market spoiler or body kit improve performance, the majority add weight and increase the drag coefficient of the vehicle and thus reduce its overall performance.
Increasing the wheel track width through spacers and wide body kits enhance the cars cornering ability. Lowering the center of gravity is another aim of body tuning dealt with via suspension modifications. However, similar to the addition of non-functioning body kits and spoilers, oftentimes suspension tuners unfamiliar with spring dynamics will cut stock springs, producing a soft, bouncy ride. It is also common to lower the car too far, past the optimal center of gravity, purely for appearance.

Detuning

Detuning involves returning a modified car to its original factory status. It is akin to automotive restoration. The term detuning can also refer to the reduction or decrease of performance in a particular area of tuning. An example of this could be where the engine is “detuned” to allow increased traction on a day where the track grip is not sufficient to handle the increased power of the tuned engine.
