Chassis Stiffening Plate

I recently added the g7 plate to my 09. Now we have a problem, my Prius has handled perfectly since then, but it frequently handled perfectly before, the oddities were rare. Has the plate solved them? Have they simply not reappeared yet? Is it Placebo effect? I own the car and am unwilling to say, I am not sure that helps someone considering it.

I consider it $50 well spent.

My own vote: It helps. Most noticeably at highway speeds, and especially around the more pronounced curves of highways and parkways.

Good luck.

 

My vote: it makes no significant difference.

Objectively, there has been no testing done that would adequately settle the issue. What little has been done shows no difference, but the methodology is limited.

 

You will find that the overwhelming majority of those who have actually tried the BT plate find that it significantly improves rear end stability. Of those that feel that the plate offers either little or no improvement, only a small percentage have ever tried it. In my case, I was so unhappy with the rear end moving all over the place under adverse conditions ( high wind - semi's and road imperfections, especially diagonal ones) that I was ready to sell the car - with only 2000 miles on it. I installed the BT Plate and the rear end became totally dead (as it should be on a front drive vehicle).

Question: Does the 2010 have the same suspension configuration?
