I just had some Maximum Motorsports full length subframe connectors welded up on my car. I was skeptical at first, but they made a huge difference. I drive over "rumble strips" on my way to work daily. I used to think that they were going to shake my car apart. When I drive over them now my car is vibration free. Increased rigidity is also noticeable during normal daily driving. My car feels more solid and stable around turns and under acceleration. I can't believe it took me this long to install sub frame connectors. A great product and a great mod. :thumbsup:
