I was on the Lexus website about an hour ago and couldn't help but notice they got some new goodies (or maybe they've had them I just never heard anyone speak about their usefulness). In particular I'm talking about the Under Chassis Brace and the Shock Absorber Set which was developed in cooperation with Bilstein which I find kind of cool. Do these mods make much of a difference when it comes to body roll and stiffness of the car? In short, are they worth it or should I stick to sway bars?

heres a link for the shock absorbers:

The chassis brace I have on my car. Honestly here is where opinions differ. My mechanic at lexus told me it stiffens the *** end. And I would notice a difference. Some people will claim it does nothing. In closing with it installed on my car. I do notice a difference. Then again could it be my brain tricking me into thinking it truly does something. Do you have the sway bar set?

I prefer these shock absorbers over coilovers. No one speaks about it as much as F-sport sway bars. My friend has the under chassis brace, depending on how hard you drive it you won't notice it.

I have it on my car and love it totally. The only thing i hate it is the design where it gave resonator clearance is hanging too low. it's lower than the exhaust pipe

I had the F Sport shocks on my car. Didn't really notice that much difference in handling from stock shocks. Not to mention the F-Sport shocks are a bit longer than our stock shocks, which made my H&R springs not as low as they were on my stock shocks.

I traded up for coilovers.

I have the F Sport Chassis brace and sway bars. I like how tight the car feels. I have other bars also. I scrape the hell out of my brace cause I'm SLAMMED!

I see. No I do not have the sway bars. I honestly want to get the set tho, It's beautiful around corners but I want less roll. The only problem I have with it is the fact that it will stiffen the ride as well.

Oh, so I guess it's made to complement the F-Sport springs.

Chassis brace makes a good skid plate

Before bags, and if carrying passengers, I would make them get out due to a speed bump because of that horrible scrapping noise

I checked with a local Lexis and they only go up to 2016. Have not made anything for my rocket
One of the main reasons is the FSPORT parts are often much better quality than most hyped after market products. This is why I only upgraded the springs, No alignments or change in camber. I may need some hubcentric spacers. Handles on rails baby

RSR springs, TOMs front and back strut tower bars, DB style CF tail
