Any Reviews on Ultra Racing Chassis Stiffening Bars




I've always had an eye on Ultra Racing chassis reinforcement bars for the W211. Was curious to know if any of you have tried out their products for the W211 and if so, what were your thoughts on them in relation to the W211 chassis.
Thanks,

Bought the upper strut bar first. Not stiff enough so made my own from chrome moly.
Lower front A arm brace...total waist of money. This thing was so weak it was not worth the time to install.I have no idea what they think this bar will do except waist your money and time. Ended up cutting the ends off and welding up my own stiffer cross over bar.
Figured not going to chance it again so made my own chassis brace for under the car. Connects the cross member to the front frame.








The first was the upper strut bar. Good improvement in stiffening the steering wheel and providing a bit less roll under heavy turning.
The second was the rear upper. Less noticeable than the front upper . It does give some good feedback with higher speed turning. Low speed not really notice.
The third is the front Lower brace. I have yet to drive the car but will update.
The fourth is the 4 point brace lower front subframe to mid car trans mount area. I'm suspecting this will give the most improvement as I have an 03 LS430 and it made a big difference in the chassis sharpness on that car.
Will install after the third brace.
The fifth bar I can't get yet as they require a min of 3 is the rear lower brace. Maybe it will be available soon. Why am I doing this? Why not. I enjoy a stiff chassis coming from a 350z Nismo with welded chassis. When I had kids needed more seats. I have a fk8 type R and the E63. Both fun cars obviously the fk8 chassis is awesome but lacks power. The 63 has gobs of power just needs some suspension and chassis work. Coilovers are in the future just not yet. This is my first air suspension car and definitely lost that direct road feeling. The chassis bracing seems to be helping bring that back.

I found the upper to be to thin as well as the lower and made one out of Chrome Moly. It has zero flex especially where it mounts to the strut towers.
These bars do work and if you Jack up a corner or front of vehicle I can not pull the bolts out do to the pressure/ load on the bar.
The ultra lower in my opinion was clearly the worst offender but great concept.
