Sway Bars
I have recently purchased a 2015 IS350 F Sport AWD. I can't seem to find a full set of sway bars for the car. I have contacted a few shops and browsed the internet for hours. All I can find is the rear bar, no luck with the front. Does anyone have any insight or links to a company that makes both the front and rear bar?

From my understanding, there isn’t too much sway bar support for the 3IS because it’s a massive job to replace them specifically the rear one. I don’t think anyone on the forums has done it.

It's also difficult to install. But if you insist on getting a sway bar upgrade, the RC350 might be more rigid and might fit. I recall seeing sway bar bushing upgrades from Japan, but they are probably not worth it.
Here are some good ideas for suspension mods:
1) Lexus RCF Front Lower Control Arm Bushings
2) RS*R Sports-i Coil-Overs or RS*R Down Sus Lowering Springs
3) Tom's Racing Upper Performance Rod Front Strut Tower Bar
4) Tom's Racing Upper Performance Rod Front Strut Tower Bar

There are 3 options that have been mentioned on the forums: T-Demand, SARD, and TRD.
Here's a link to another thread with the same question, and links within it to the products: https://www.clublexus.com/forums/is-...n-f-sport.html

Yes, TOM'S makes front and rear upper strut tower bars. The lower chassis braces were discontinued. I think the front lower would have been good addition, but it's gone. Ultra Racing makes some braces.

And on Nigel's page it clearly says TRD Sway bar set, and they give you the option of IS250, IS300h, and IS350. Once again, not sure what to tell ya...maybe when you order them they say they don't have them...kinda of a waste to have the product online though.
But since they include 300h which is the 3IS body style....ummmmm, yeah

So it would be only if someone had new old stock they were selling.
Or if someone took them off the vehicle and was selling them...at least it would confirm they did exist.
The SARD's one had a group buy going in 2016 as well.
Not sure if it actually went through though.
Once again, probably discontinued.
I think the complexity of taking the car half apart to install at least the rear one drove people away from purchasing these items in high quantity...and ultimately led to the products dying off.
There were some that did install them...but it seemed like a handful of people on here.
They're out there, just a matter of finding them if you really want them.

Heres a little known product by Think Design Japan that will improve handling. It is a rear member bushing and collar.
http://www.think-design.jp/r_sus_member_collar_top.html
Cost is ~$390 for the collars and bushings. A seemingly steep price for a small product, but it's my understanding that the bushing design of the rear member causes considerably sloppy handling in exchange for fluffy 'lexus' comfort (think front lower control arm bushing).

Sard does make sway bars for 3IS, but for RWD only, so only the rear bar is compatible with the AWD. I have it installed in my AWD.
those collars that TOPENDMS posted are very popular upgrades in the past specially in the RWD world. They reduce wheel hop at launch by reducing the movement of the rear subframe during hard acceleration. T-Demand claims that their sway bars set are compatible for both AWD and RWD. I have been wanting to get the fronts but due to $$$, I would like to see someone confirm that they do fit the AWD before importing a set than find out they don't fit.
