There's a long thread here on aftermarket lower control arm bushings:

I had some excessive front inner tire shoulder wear on my 2011 IS 350 AWD, and was looking into replacement bushings. I decided to try the stock Lexus bushings for the RC-F, which some here were using and said they were satisfied with the tire wear improvement + handling upgrade. Plus, they are a lot cheaper than the aftermarket ones. I've had the RC-F stock bushings on for around a year now, and am happy enough. The front inner tire wear isn't completely gone, but it's a lot better. Ride and handling got a little stiffer, but not what I would consider harsh at all.

I think this is exactly what I was looking for. I couldnt remember if it was RC-F or IS-F though. Theyll work on a 2012 IS 250 RWD thought I am pretty sure? My major issue is control, loose steering, swaying, drifting, following the road, pulling hard etc. Swapped tires twice, 2 alignments, nothing has fully fixed it so this was the last thing I was recommended to try.

Slightly O/T but does anyone know the inner and outer diameter of the OEM shell and the lower control arm pivot?
Poly bushings should not cost $3xx! Talk about a racket!
I have access to a lathe and making a set with a thrust surface in 80 or 90 durometer is definitely possible. Short of greasing it every so often to prevent squeaks, thats the only real hardship here.

The price includes the cost of two brackets and labor to press the bushings into them. If you have your own shop press you can buy them cheaper without the brackets and reuse your stock brackets:

I know the squeek well from previous vehicles fitted with poly. I broke down and drilled holes through the shell to the core and used a rotary file on the poly to make a circular ring so grease would flow 360°. Because this has a load bearing lip (thrust surface) your feed cut into the bushing needs to branch out there too. Just don't cut the grove to the edge as it lets water in too easy. Then tap the outer hole for grease zerk and pump it full of silicone lube. Usually lasted about 6 to 8mo. Hope its worth it.
Let me know if you need more detail but silicone grease forced in under pressure does the trick and there doesnt have to be much of a grove. Make sense?
And thanks in advance!!

^^ Unless you you know what the factory ones are in your car it doesn't matter (they could be zero or combination of all three). The offset from zero (no offset) changes the caster a small amount. That said just buy the zero ones.

How are your tires holding up for you? I feel the need to just add that I am in no way bashing RRs product. I think poly altogether is going to be too hard for the roads here. And, the car has 120k so there could very well be another issue that the soft bushings is covering up. That said, for now I want to go back to a softer bushing, even if it has a little tire wear as long as it's better than the 350 ones it will do for now.
I'm running IS-F take offs and getting even wear across the tire. That said the scrub from turning sharp is taking a toll on the edges but nothing drastic. I've got the toe and pressure pretty ideal for how the car is used. The rear tires could go first at this rate!
Order the RC-F parts for maintenance free DD....
If I ever do go poly they will have grease fitting installed. It's silly to have to pull it apart to lube the dang things. Heck they should have it that way anyway.
