Poly no, solid yes, definitely.

Had Figs and RR Racing LCA poly bushings and after about 2 years, had to degrease both. When pushing the “spindle” or whatever the cylindrical metal bushing is called, there was no grease remaining on either poly bushings, meaning they were both completely dried out and squeaked pretty badly going over bumps/speed bumps.

So over time, the poly LCA’s will need to be removed and regreased, at least from my experience from owning both.

Before I sold my ISF last June, I had the RRRacing USRS LCA bushings for four years. I never had a noise or squeaking issue with them. When I installed them I used the special grease supplied by RRRacing. IMHO, they were one of the best handling mods I made to the car.

Interesting. Don't think I got any grease from RR in my package. Part of the LCAs were pre-lubed though... but I ended up buying a tub of Formula5 from Amazon to put a bit more on the spindle.

Anyways, 4 years is pretty good though. I do remember seeing in their instructions that they explicitly stated they would need to be re-lubed at some point, but I don't think they provided any kind of interval. I suppose its just an as needed basis.

My Figs 90 was due for a refresh. It was noisy in cold weather, but quiet above 40 degrees when I took it off. I cleaned and greased it before passing it on to its new owner.

I've had the RR bushings for about 2 years. A very immaterial amount of NVH and more feedback through the wheel and linear braking, especially on the track. Not night and day difference for me but still a decent mod.

Glad I found this thread. I noticed on Fig's site it appears they only have the 90 and solid metal now. I was torn between RR and Figs. One question I have is the video of the RR racing bushing shows almost no movement under braking which is good but then it makes me wonder where is that stress that was one being absorbed by the stock bushing going... it has to be going somewhere... and is that then wearing out or putting strain on other components?

I almost feel like from what everyone is saying I want to get the Figs 90 (they are now attached to a black bracket instead of silver, is this correct?), but not really for performance reasons honestly. Mainly to prevent tire wear. This would be for my RCF but this is the biggest thread I found thus far talking about both brands.

I want to keep the "luxury" feel of the car, even though it's an F.... I replaced ALL bushings on my STi to race poly bushings and as awesome as it handles it's a freaking harsh/noisy ride... I look back now and say I should have gotten the street version of all the bushings instead of race. I was young and thought it was super cool. Now being older I realize that my body just doesn't like that for extended periods of time. When I get out of the car after 30 minutes and my back and or body hurts, I've gone too far in modding...lol. I totally get the NVH is 100% subjective. From what most are recommending on here with Figs I think that's my best bet. I just want to make sure I am not missing something in terms of their products since I only see the two as mentioned above. I want a better feel than stock (even though stock feels completely fine to me) but without any increase in vibration or harshness that would make then seem like "we've past a point of comfort".

You won't be unhappy with the Figs 90 durometer LCA bushings. They solve 99% of the problems for anyone on the street. Better tire wear, more stable under hard braking, minimal change (if any) in NVH. If you said you plan to track the car but don't want the NVH of a solid bearing, then the RR Racing would be the best compromise because it limits end to end movement where the SuperPro bushing does not. This makes the car a little more stable under hard braking you experience at track speeds. I hear you on the race vs. street. Lots of racecar parts are miserable on the street, but essential for the track.

Since you want to keep the luxury feel, look into the new offering from RR Racing. They now have one with a softer durometer so there are now 3 different versions you can get from them. Other than that, can't go wrong with either Figs or RR Racing.

As someone who ran the RR USRS bushings for 4 years I have a good idea of how they feel over an extended period of time. They do what they are labeled as (Ultimate Steering Response System) and better explained by what Lobuxracer said in his post above^^^........that being said I just switched to the Figs LCA bushings and there is a noticeable difference in NVH between the two. I am enjoying the isolation (albeit not major it is noticeable to me) of the Figs LCA bushings and there is definitely more compliance that you can feel through the steering compared to the zero deflection bushing that RR offers.

Both good LCA bushings from both vendors! Just buy which one will suit your driving style better

Appreciate all the information! I have ZERO intention on tracking the RCF... If I want to go to the track I'd take my STi or Daytona 675. This is only around town and to be comfortable..lol

I am more than likely going with the Figs. I think I like how they look better (as silly as that sounds). I have other RR components so no issues with that. I just feel like after reading what everyone is stating the Figs is where I am going to be happy.

Dumb question but I didn't see it mentioned. Does an alignment need to be done after these are installed? I have a lift in my garage so installing them shouldn't be difficult to me. Does the suspension need to be loaded however when tightening the bolts once they are installed?

Is there anything that is recommended as well while one is under there installing these? IE: You should definitely install "Part X" because you are there and already have taken other things off... might as well do XYZ...etc?

Thanks,

X3. I have the RR USRS. I felt no discernible difference when I put them on my 13 ISF. I’m replacing them with the figs solid mounts, but the RRs will go on my daily is350.

Alignment all depends on how long you want to run your front tires. If they're near end of life, and you'll be getting an alignment when you put on new tires, then no. If they're fairly new, get an alignment.

If you only change the rear bushing, you'll need to load the suspension for the front bolt, but not the rear nut. The poly bushing rotates freely, so there's no need to load that bushing when tightening up. I did front and rear which makes it much easier. No loading at all, just tighten everything down and connect the rest of the bits and you're all good. The front bushing is a huge PITA to remove if you are not familiar with removing staked bushings. For your purposes, I'd just load the suspension, tighten the front bolt, tighten the rear bolt and call it a day.

There are no complimentary pieces recommended to install unless you want to put a poly bushing in the front. I wouldn't do it if I had your use case.

I'm not sure how I missed your comment but thank you! I just went to their site and saw this. Seems like his is 88 dur compared to their higher 95 and figs' 90. I need to email Rafi and actually ask questions but this might be the best bet since it's slightly softer but also does zero deflection. The only thing that I see on RR's website is that they recommend this for AWD vehicles which mine is not. My one concerns with the zero deflection and or thrust washer is that it would create more NVH. Looking back years ago my friend brought his IS to my house and we did in fact (confirmed after I called him just a few days ago) install the USRS on his car. It was a fairly simple job but I do remember him giving me a ride and it was noticeably louder in the car. I think we both were somewhat taken back by the noise but then when I asked him recently he said it doesn't make that noise or perhaps he's used to it. I know he said the steering was better.

I wish this was as cut and dry as solid spherical bearings our mounts where I know 100% that this would not be what I want... Just sucks that there is at least two choices (figs 90, or rr racing 88 usrs) and I'm not 100% sure on which one to do go with... 3 if you count the original RR racing 95 dur usrs. It's not even a question on quality. They BOTH look like phonemical pieces.

I have the figs and it's super quiet so far... not sure what noise you are talking about?

Also NVH?????
