sorry noobie here, can i ask is it true the strut bar help car cornering better? theoritically, i dont see any purpose of the bar.. a piece of bar help cornering?
Quote from Wikipedia:
A strut bar or strut brace is a mostly aftermarket car suspension accessory used in conjunction with MacPherson struts on monocoque or unibody chassis to provide extra strength between the strut towers.
With a MacPherson strut suspension system where the spring and shock absorber are combined in the one suspension unit, the entire vertical suspension load is transmitted to the top of the vehicle's strut tower, unlike a double wishbone suspension where the spring and shock absorber may share the load separately. In general terms, a strut tower in a monocoque chassis is a reinforced portion of the inner wheel well and is not necessarily directly connected to the main chassis rails. For this reason there is inherent flex within the strut towers relative to the chassis rails.
A strut bar is designed to reduce this strut tower flex by tying two parallel strut towers together. This transmits the load of each strut tower during cornering via tension and compression of the strut bar which shares the load between both towers and reduces chassis flex.
A direct result of this is improved chassis rigidity (similar to that gained from a lower tie bar); hence, the
understeer is reduced, tire wear improved and metal fatigue is greatly reduced in the strut tower area. Following the aftermarket's lead, some manufacturers have started fitting strut bars to performance models, including the NISSAN Skyline R34, certain Nissan Sentra models (e.g. Sentra 2.0SE), Acura CL Type-S, and the HOLDEN VY II Commodore, as standard equipment.

talkin bout the strut, yes it does make ur car feel more stable when cornering, but this mentallity will make ur tyre cepat botak, since it's stable, u'll tend to take sharp corners or accelerate more when goin thru corners, so it end up makan ur tyre, save ur tyres! ahaks!

I rather let my tyres go bold than to lose my life at any corner
how fast can a tyre go bald anyway. 2-3 years? Look at wikipedia's statement above...improve tyre wear
