Most of the original owners want to improve the performance of the best car through a series of modifications, can also lead to the frame and therefore did not expect variations. What is the reason? As everyone knows, are the source of all modifications from the hub. Replace the wheels have to bring many benefits with wide flat tire to achieve results, but a flat tire caused by ground shaking filter needs to be replaced, but the suspension was filtered; the choice of hanging soft suspension failed to play the best condition, so the bias stiffer suspension as the preferred, more rigid suspension shock filtering effect is unsatisfactory, the results of the vibration is transmitted directly to the frame, the frame variants over time lead. ● all start because of wheel General Tire factory models offer material for tire rims, although durable, but the general appearance; and, relatively speaking, alloy wheels light weight, small inertial resistance, making high precision, small deformation at high speed rotation, will help improve straight running Auto Performance Parts, reduce the tire rolling resistance, thereby reducing fuel consumption. Thermal properties of the alloy material is about three times the steel, heat dissipation, for a vehicle braking system play a role. Seemingly modified wheel has a number of benefits, if equipped with narrow tires, the tire is too thick, the tire size is too small to be difficult to play the advantages of the hub, so a large width and small thickness with modified wheel tire becomes inevitable choice. ● For best results replace tires For the sake of play the best performance, increase the ground contact area of the tire may improve adhesion between the tires and the brake, bend performance is improved. The low profile tires can reduce tire deformation on handling produce, so more direct control response, sensitive, and indeed from the appearance is very beautiful, but too thin tire vibration through the ground to produce the effect of filtering very poor, then the need to replace a filter shock suspension racing coilovers. ● consequences appear to replace suspended Tires for retrofitting after poor ability to shock, can only be achieved by replacing the suspension filtered shock effect. If you choose a softer suspension shock absorbers poor problem can be solved, but the car's performance will decline, softer suspension in cornering, braking vehicle big swings, for the replacement wheels and tires simply spoil such a suspension.
