This was far better than I expected it to be. Despite a bout of impulisve spending on things I thought I didn't need, in reflection I think this is an excellent use of £330 on the car (plus £160 labour to fit along with the roll bars I ordered). The difference to the body rigidity is immediately noticeable.
It's hard to communicate but when cornering, the connection with the road is more telepathic. You are that much closer to knowing what the suspension and the tyre contact patches are doing with the weight transfer, since so much of the body movement is removed. It felt good before, but feels great now. If you look at the beatrush chassic braces, they appear identical, yet are about 3 times the cost. I am not sure who copied who but at this price I don't care, and amazingly the weight penalty is tiny. Less than 10kg all in, especially since the front shock brace replaces the standard heavier item on my sport.
The rear performance bar adds some nvh, but don't believe anything you read saying it's intrusive. On initial pull away there is some transmission of vibration from the rear diff housing, but above 5mph it dissappears completely and leaves you with a slightly a,plified gear meshing whine, that gives about 10% of the impression of a straight cut gearbox. It's enough to sound great but not enough to grate at you. I could do with a bit more of it frankly.
I can't comment on the handling improvement itself, as much of that will have come from the sway bars, but the combination I now have is better than I ever imagined.
If you are into extracting the best possible handling chassis you can from what mazda started with, these are a great option.
