Strut Bar BMW E90 3 Series improve your car Handling & Stability. Also known as a Front Strut Bar, Front Tower Bar, Tower Brace.

Specification: 2 Points. (For 325 2.0 2005)

When you corner, the whole car’s chassis is twisting slightly. In the front (and perhaps at the back, but not so often) the suspension pillars will be moving relative to each other because there’s no direct physical link between them. They are connected via the car body, which can flex depending on its stiffness.

A strut brace bolts across the top of the engine to the tops of the two suspension posts and makes that direct physical contact. The result is that the whole front suspension setup becomes a lot more rigid and there will be virtually no movement relative to each side. In effect, you’re adding the fourth side to the open box created by the subframe and the two suspension pillars.

When any of the wheels loses contact with the road surface, there will be a deviate in handling; each of the suspension system should keep all wheels on the road surface in spite of hard cornering and in change of steering position. It’s always pleasing that that car can be set for a tiny amount of understeer so that it responds predictably to a turn of a steering wheel and the rear wheels to have a smaller dip angle than the front wheels. However this may not be achievable at all times due to the vehicle load, road condition, weather, speed and this consumes excessive time for the driver to adopt.

BEFORE install Ultra Racing’s strut bar and lower arm bar to car BMW E90 3 Series while entering at corner: The weight transfer and force gathering on one side, causing unstable handling and increasing body roll.

AFTER install Ultra Racing’s strut bar and lower arm bar to car BMW E90 3 Series while entering at corner: The force will spread out by Ultra Racing’s strut bar and lower arm bar, stabilize the car and provide solid handling.

Life and safety is more important than everything. For daily road user, we are friendly recommended you to install our STAGE 1 Package.
