Bushing options
Does anyone sell a full set of suspension bushings? I know FIGS offers some control arm bushings, but I was wondering what other options were out there (aside from dropping thousands at the dealership)?

Figs does more and rr-racing sells the rear flca bushing, not knock rr but I've only purchased through figs, could t be happier. Here's the other company http://www.rr-racing.com/Lexus-Lower...isfxlca001.htm

It is not just a bushing, it is much more ( we do not re-use a stock Lexus LCA bushing housing). Our Ultimate Steering Response System (as we like to call it:-) includes a redesigned aluminum housing that is significantly reinforced to withstand the massive thrust loading that our design requires. I'd be happy to answer any questions about it.
Picture below shows a black bushing we used for the initial production/test run. Actual final production models have a red 95 durometer poly bushing. We have track and street tested the Ultimate Steering Response System (USRS)*extensively* and are very excited to release it:

There are only a few bushings you can buy at the dealer. Most of the time you have to buy the part the bushings are mounted in to get new bushings, especially with Toyota. Figs is focused on putting poly where it is most needed. The factory updated the rear bushings when they changed the suspension, so later model cars have better bushings.

The turn response with our bushing is phenomenal, but one of the biggest improvements is under braking. Our first time at VIR, we were running 150mph on the back straight and 140mph on the front straight into the braking zones, and I can tell you the car was wandering under heavy braking due to the toe changes induced during braking (it also chewed the insides of the front tires). If you look at the stock bushing design, it allows fore/aft movement, whereas ours utilizes a high strength thrust washer, redesigned bushing, and significantly beefed up 6061-T6 housing to resist the massive thrust loads that you get under braking.
We designed a new housing because we did not feel comfortable enough reusing the stock housing, knowing that it was not designed with the intent of taking all the thrust loads it would see with our new design. If you look at the stock housings closely, you will see that they are extruded from aluminum so that the grain alignment end up parallel to the thrust load. Extruding the final shape of the housing makes it cheap for Lexus to produce, but its not good if you are worried about long term durability/fatigue issues with the redesign we wanted. So in addition to significantly beefing up the cross section of the housing, we also machined the housing so that the grain flow would be perpendicular to the applied thrust load.
Designing a bushing/housing system also makes it easier to install, so that folks would not have to press out the stock bushing. So once you install our USRS, you can throw the stock LCA bushing in the garbage where it belongs:-)
Lastly, our USRS for the lower control arm is 100% made in the USA, from the design, material sourcing, to the manufacturing, this is very important to us in order to maintain quality, and for other reasons.

RRR are you planning to offer any discounts to get your bushings out and get some reviews? At your price point you are up against an established vendor here and might have a hard time gaining traction. I know white line used to offer initial discounts to get the products into the community and get some reviews .

Besides Rafi, I have these bushings installed (proud guinea pig).
Here's my testimonial:
I could explain the car's steering like this: it feels much more like point-and-shoot now than it did prior to install.
The steering is more direct--this is due to a big reduction in the amount of deflection under turning and braking (the bushing is not only solid, but the housing is independently machined to be much beefier than stock). The steering feels stiffer--this is due to the increase in caster.
The car is much more confidence inspiring not only at high speeds, but at braking at high speeds as well.
There's another aftermarket bushing offering out there, but those bushings reuse stock housings. They even cost more.
The car feels so much different (I have an 08) that I am sort of astonished, especially since I didn't expect such a big delta.
I hope Rafi provides insurance for spirited-driving or "hooning" tickets

Just got off the phone with Rafi, good guy and very knowledgeable! Sounds like he has a bunch of stuff in the pipeline for the F which is exciting to say the least, to have another vendor willing to support the F for aftermarket performance parts! I will be ordering these soon as they should be out by the end of the month.
