Default Front sway bar bushing size?

What is the OEM front bushing size on our cars it's a 2011 ISF I know the bar is 28.6mm but what about front bushingu 28mm? or 29mm ? Did a search and couldn't find accurate information. I'm changing over to poly front bushing.

Edit- I found bushing supplier Prothane Suspension Parts out of Texas they carry SuperPro Bushing in 28.5mm size. Prothane Suspension Parts great customer service. I ordered bushings from them a few weeks ago and they also help me out with this order I had initially ordered the wrong size they were able to expedite the right size for me quickly and get them to me hopefully by this Friday or Saturday the latest so I can start my suspension project. Also installing sway bar locks Designed to stop lateral shifting of the sway bars.

I replaced mine with these https://shop.advanceautoparts.com/p/...m=sway+bushing ... dunno the size but if you want insertion to be easier, get the one with a slit... as far as for a review, i can't tell any difference but the stock ones were pretty smashed but i bet they were still good... i was just changing my alternator and decided since i'll have access why not change it... i have 130k miles on mine... i didn't go the poly route just because of the maintenance needed to grease them... if u don't have a lift, it's a hassle to unscrew the bottom undercover to get access to the sway bar and didn't feel like needing to do that every winter in my garage... My figs poly LCA need to be regreased but have yet to do that...

Default Does size really matter?

I bought the TRD sway bars for the IS-F (used). Since they're used, I wanted to get new bushings for them so I got my trusty callipers out to measure the diameter of the bars. To my surprise, the diameter of the front is actually smaller than the stock bar, coming in at 24.5mm. You know what else has a sway bar with that diameter? A 94-96 TOYOTA CAMRY!! Who would have thought?! Lets hope Toyota hasn't changed the mounting bracket in 22 years because I ordered a set. The rear sway bar is the same as stock - 17mm. Thought this might be an interesting little tidbit for y'all.

Is that smaller front TRD anti-roll bar adjustable?

A bar's diameter is just one of several factors used to determine it's stiffness.

Is the TRD bar stiffer or softer than the Isf's?

It’s a good question and Im not sure. I can’t find much info about them out there. I believe they were only available as part of the TRD (CCS-P) coilover suspension. So I’m “assuming” (hoping) the bars and coilovers have been tuned to work effectively together.

Are those the TRD (CCS-P) coilovers you have in the picture? I noticed that your sig says you have the RR's, but they're blue anodized as far as I know.

Good eye, yes they are the TRD. I had the RR-Racing, but then these came up on bidjdm and I couldn't pass them up, so I sold the RR's. There's still as set of the fully adjustable TRDs available, I preferred these because you already know how I feel about adjusting things! (and admittedly these were less costly).

I see the bidjdm is almost 7,000 dollars for these...but the RR Racing is 2500....did you get these for less than 2,500 dollars? if so...how?

I wish! - but not at all. I had to fork over additional money on top of what I sold The RR-Racing for. This set was much cheaper than the ones currently listed though.
There are two variants of the TRD coilovers: non-adjustable (in terms of compression and rebound) which I purchased, and fully adjustable. There’s definitely a premium on the fully adjustable.
