First time I've seen something like this....What's it suppose to do?? Does it replace an OEM item??
I'm not adverse to fitting aftermarket parts, just jave no idea who this thing is suppose to improve anything - For reference I find the ride quality on our IS300H as good/better that on my old BMW that had £2.5k worth of custom tuned Bilstein suspension on it :)
It was developed and patented by Yamaha, and quite clever, in that a car steel bodyshell is the largest spring in a car and therefore needs damping too. The device is actually a super high pressure shock absorber mounter transversely attaching to major structural points on either side of the car. It gives rigidity when required, but also 'gives' where neccesary, by way of its incredibly small 1-2mm travel. On the IS300h, which still has stock springs and shocks (OEM are monotubes!) only one of these is fitted, at the end of the rear chassis rails; I suspect the cvt gearbox has too much girth and doesn't allow a front one to be fitted. On my BMW I have them both; the front one connects the two rear mountings of the front subframe.
The main effect is the whole car feels tighter and quieter, rather than stiffer and noisier when ordinary strut bars are fitted. On quite a few Lexus models these come as standard, including the recently launched 200t F sport.
Yes I am a fan of the handling of older BMW's, but with a few recent mods my IS handles better than any of them.
