Additional Info

Contrary to popular opinion, a strut tower bar is not under compression during hard cornering. During a maximum-effort turn, the strut on the outside of the turn actually is pulled out from the center of the car, not pushed toward the middle. It's only under severe downforce caused, say, by a pothole, that the two towers try to get closer together. Either way, the result is the same: vague, wobbly handling under hard cornering as the camber changes randomly. Long-term the consequences are more profound: fatigue cracking of the chassis in the strut tower area. Add a strut tower brace, or upgrade your OEM brace with this welded steel brace from AEM. You'll feel an immediate improvement in cornering precision. And you won't feel the struts coming adrift in the engine bay as you go over a speed bump a little too fast. Installation is easy, and all hardware is included. AEM warrants that its Strut Tower Bars will last for the life of your vehicle.

JM Auto Racing is your one stop shop for all your automotive needs. From our superior customer service, fast shipping and unbeatable prices, JM Auto Racing is simply the BEST. Make your next purchase from JM Auto Racing today and come see for yourself.
