Areas of modification
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 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 bucket seats (racing 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
Main article: Engine tuning
Engine tuning as of late 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 CRFP. 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.
Terms
"Streeted" or "Tuner Cars" are Japanese imports, such as a Toyota Supra, Nissan Skyline, Mazda RX-7, Subaru Impreza, and the Mitsubishi Lancer Evolution series. These cars are most commonly modified with the more expensive mods available. The most popular modifications include suspension upgrades, exhaust systems, and turbos.
Legal requirements
Many countries have legal requirements in regard to what car owners can and can't do in relation to vehicle modifications. For example, all vehicles in Victoria, Australia, must conform to construction standards to ensure vehicles provide drivers and passengers with a maximum level of safety. There are also restrictions for P Plate drivers which can prevent young drivers from driving modified vehicles.
In the United Kingdom and the Netherlands it is illegal for any car to have blue lights as they are used by the emergency vehicles.
In Scotland and Denmark, it is illegal for any car to have neon underlights on a car as it distracts other drivers. In the Netherlands neon is allowed under the car but only when the car is on display, if the car is on a public road the lights have to be switched off.
Recently, Belgium issued a new law which describes that bodykit parts need to be approved for safety issues.
Sanctioning organizations
Many organizations involved in competitive motorsports establish safety guidelines that far exceed legal requirements placed on civilian street legal vehicles. The NHRA, IHRA and SOLO programs all require that vehicles pass inspection to ensure that all regulations are being complied with.
