its more like for looks. I guess there may be some use to it but very minimal. Sway bars have more efffects
....unless you have coilovers, 17's with 235/40/17 and track race the car and drive like me, then don't get it. The strut bracing helps when you're going stiff in suspension setup because only then, when driving at the limits will you feel the difference. The strut brace will make it feel better and improve handling and feel of the car. It will not make you faster unless you can use the solidness and adjust your driving to make the most of it. I wonder why I haven't gone with strut bracing yet.... I'll have a shop put in a FIA/SCCA approved roll cage instead.
