A front strut bar is designed to reduce this strut tower flex during hard cornering by tying two parallel strut towers together. This transmits the load of each strut tower during cornering which ties the two towers together and reduces chasis flex.

When taking a turn a car's strut tower normally flex， resulting body flex and losing some traction. As a strut tower bar is designed to keep your car's strut tower from flexing， they distribute the pressure apllied to one strut tower when taking a turn to both towers instead of just one. This keeps the wheels in position. Keeping the wheels in position helps keep the tires in the desired position on the road and this will help to improve traction on the turns.

The front strut bar can be used to prevent the oversteerbehavior which always happen to the RWD cars.

Ultra Racing is proud to bring to you the first of its kind in the country， the MULTI-POINT Front Strut Bar.

How does it work?

Understanding Between Chassis and Handling : : :

A car chassis is carry by 4 wheels and 4 shock absorbers. When driving on bumpy road， the shock of impact will be absorb by shock absorber， however if the chassis is not strong enough to support the shock absorber， the shock of impact will not all absorb by shock absorber but by chassis， causing chassis flex. Same thing happen when make a turn on corner， chassis will be twisted by the force of weight transfer. Therefore， the handling will be rough and hard to predict the movement of car.

To soft the chassis flex problem and improve the handling， the Ultra Racing's chassis strengthen parts is born， we will explain how this product works on you car. The stronger chassis， the better handling.

Strut Bar and Lower Arm Bar : : :

BEFORE :

Part of the shock of impact transfer to the chassis， causing wheel house and lower arm deforming.

AFTER :

Equip with the Ultra Racing's strut bar and lower arm bar， both side shock of impact will be neutralized.

< < < While entering at corner > > >

BEFORE :

The weight transfer and force gathering on one side， causing unstable handling and increasing body roll.

AFTER :

The force will spread out by Ultra Racing's strut bar and lower arm bar， stabilize the car and provide solid handling.

Fender Bar : : :

BEFORE :

The joint between A-pillar and front chassis will be push and twist by the greater shock of impact and drag force， causing damage on chassis.

AFTER :

Ultra Racing's Fender bar will spread out the force and strengthen the section， prevent further damage and offer stable handling. Recommend for user of sport absorber

Side Lower Bar : : :

BEFORE :

On uneven / bumpy road， center section chassis will have different level of body flex cause by the weight transfer between front and rear.

AFTER :

Ultra Racing's side lower bar will stabilize the weight transfer between front and rear， it can also minimize the damage from side impact.

Anti-Roll Bar : : :

BEFORE :

When turning in corner， the weight transfer will make the car sway a side， causing body roll and more difficult to turn in to a corner， weaken the steering respond.

AFTER :

The upgrade version of Ultra Racing's anti roll bar will be more effectively preventing the car sway a side at cornering， greatly reduce body roll and high stability in cornering

All raw materials has been made and tested with satisfactory result.

Why we use Steel instead of Aluminum?

First， steel is stronger than aluminum for the same size and thickness. In order for aluminum alloys to be at least the same strength as steel， it has to be at least doubl
