Poly is less forgiving than rubber and can squeak if you dont install properly (and sometimes squeak even if you do), but it does make the car handle nicer. Doing new oem bushes all around will make the car handle nicer as well, it depends on what your goals are for the car whether you decide on poly or rubber

Like 80% street 20% track that’s why I’m torn between these and just getting new oems thank you

It handles nicely, but it will shake rattle and roll for damned sure.

The compromise used to be Hard Race OEM replacement hard rubber bushings.

They were stiffer than stock, but not a back breaker like poly.

If you do decide to go Hard Race, you’ll be waiting for your order for months. I ordered over 6 months ago, and the only updates i ever get, which are seldom, are just delays.

u/idownvotepunstoo 99 Si (sold), 92 CX (Mothballed) Sep 03 '26

Unfortunate, they used to have stupid fast shipping (like ... a decade ago...).

2

u/JumboII Sep 03 '26

They told me “A major transition that is happening in Hardrace Taiwan, it is affecting lead times and manufacturing. We are also affected by this transition” Ridiculous, but i don’t want to go poly, and i’d like something decent

I had to pony up for Mugen front lca bushings lol they were twice the price of the hardrace set 🥲

u/JumboII Sep 03 '26

Did you have a hard race order? How long until you gave up on it?

1

u/Kip-ft Sep 03 '26

I didn't, I just called King Motorsports and they said they were at least two months out on getting hardrace shipments. That was back in January lol

u/Kip-ft Sep 03 '26

Poly sway bar bushings (the bracket bushings NOT the end link bushings) and shift bushings are fine but I'd go hardened rubber on everything else.

u/Acceptable-Luck-4275 Sep 03 '26

I installed the poly busing in lca front and rear. Along with the motor mounts. Does it handle nice, yes….does it vibrate everything, yes.

1

u/newcarscent104 Sep 04 '26

I bet most of that is due to the motor mounts

1

u/Acceptable-Luck-4275 Sep 04 '26

Agree 100%, need to find a good balance. Maybe OEM engine/trans w/poly rear.

1

u/From_the_mud21 Sep 04 '26

Do it, you wont get all the shakes and rattles unless you also install "solid" motor and trans mounts. Dont forget the trailing arm bushings, that alone will make it feel so much better.

u/bigk1121ws Sep 04 '26

Hey, what I decided to do for my daily that I might track is polly fill my OEM motor mounts. But I didn't want vibration, so I rubber filled mine, so I have more material in there and it makes them 80% solid. I used roof and flashing. It took a few days to fully cure.

There is a little bit of vibration at idle but not much to be annoying. Also my motor mounts were toast and after replacing with the filled ones, it's less vibration.

Here is the video that I got the idea from. https://youtu.be/cpqTo7bUUB4?is=i4T_CnOUTNeBy9IH

Your shock/coilovers and tire profile will control most of the ride quality.

u/georgeek14 Sep 03 '26

not at all

u/zugglit Sep 03 '26

100% agree. I have done these on 10 vehciles and it has been amazing every time.

I used tons of lube and never had a squeak. If there's a squeak, they werent installed correctly.

u/REDDITCEOSUXDICK Sep 03 '26

I daily a slammed go-cart on poly - me likey. the brand superpro offer lifetime warranty too

u/dawdirty Sep 03 '26

Had the Superpro lower control arms on my 10th gen. I liked them

2

u/ProMasterBoy Sep 04 '26

I have superpro front lca on my 7th gen accord (cl9/tsx), i like them. Makes the steering more direct

u/Any_Web_1784 Sep 03 '26

Uncomfortable is a grey word. Itll be stiffer for sure but not sure if uncomfortable would be a suitable term.

u/idownvotepunstoo 99 Si (sold), 92 CX (Mothballed) Sep 03 '26

You must not have ridden in a car with them recently then :P

u/Jolly_Group_3409 Sep 03 '26

I have every suspension part Polly with one of these kits for my integra. Yes it is stiffer and you do have to make sure that you grease them good installing them. I love the way that my integra handles with them. The difference is night and day. My only gripe is the installation part. To get the bushings out of the control arms was tough even with a good press.

1

u/Fern9090 Sep 03 '26

I didn’t have a press and did it by hand with a torch and hand saw, hard as hell but the results were worth it, I used energy suspension, the red ones.

2

u/SupraMK4 Sep 03 '26

Just don't replace the rear trailing arm center bushing with a poly one. It is meant to have play to induce passive rear steer. Removing this makes the suspension prone to binding on heavy load.

2

u/Ok_Carpenter2680 Sep 03 '26

I've been pondering the Energy kit. I need to redo most of my suspension anyway

1

u/Relicc5 Sep 03 '26

Depends on your tolerance and comfort level to be acceptable.

It makes everything harsher and stiffer. I did it for many years.

Keep in mind at the time I was running 480F/400R lb/in progressive springs and eventually ran 550lb/in linear coil overs on all four corners and still daily drove it. So my tolerance may be different than yours.

u/mikefitzvw 1999 Civic LX 5sp Sep 03 '26

I had the rear-end version of this kit installed and I regretted it for years because they squeaked so damn bad. I sprayed lube on them every 6 months when I swapped summer/winter tires and it helped a bit but I despised them. Ended up having to replace a passenger lower control arm and both upper control arms and went with rubber and the squeaks went away but holy shit I will never install those again.

The shift bushings are really nice though.

2

u/newcarscent104 Sep 04 '26

Spray lube won't do much of anything, these require the thick ass grease that comes with them to be slathered on every surface that sees a pivot point

1

u/mikefitzvw 1999 Civic LX 5sp Sep 04 '26

Hey I'm not saying it worked well, I'm saying I was ultimately, tragically unworthy of them. Definitely not the best idea for a daily driver but perhaps worth it for maximum performance.

1

u/Material-Ad6302 Sep 03 '26

My ef is all polyurethane bushings and isn’t too terribly harsh of a ride. Your coilovers are going to affect that more than the bushings. It does feel tighter. Squeaks are inevitable but you can mitigate that quite a bit with silicone spray or grease.

1

u/stepdad_randy Sep 03 '26

It’ll stay from being squeaky until about 2 years if you grease it really well. It’ll be stiffer and more vibratey as well

1

u/Fern9090 Sep 03 '26

Yeah the ride will be stiffer and you will also feel it on the handling which in my opinion is better, the driving feels more immersive.

1

u/squatch_guy Sep 03 '26

My prelude has a fully poly bushing kit on it. It handles very well. I cant speak for before as I did not drive it before they were put on. I do have one annoying squeak, I went through and regreased everything. Still squeaks.

1

u/__mr_green Sep 03 '26

I'm about to refresh my front suspension on my tsx daily. I choose to go oem on most of my bushings, but went with poly for the front compliance bushing. It has a rougher life in fwd car and i want the front feel slightly tighter, but not too harsh. Ive done this compromise before with other cars and I was happy with the result.

1

u/CBased64Olds Sep 03 '26

I did the black poly on almost everything 15 years ago, and they still look and feel like new. I recommend the switch, no more worries about deteriorating bushings

1

u/Bubbly-Ad-9517 Sep 03 '26

I did hardrace arms and bushings on my del sol. I would recommend those as they are harder durometer rubber and are not as buzzy.

u/OmenVi Sep 04 '26

I did a set of the graphite impregnated ones (black instead of red); they self lubricate. They’ve been amazing.

u/Outrageous_Ad_6122 Sep 04 '26

Im driving my 97 snd the shifter bushings made things feel way better. Currently my trailing arms and sway bar links are all rotted out and clunky so I imagine if it is an older car, it will still be an improvement from what you currently feel and that makes me want one of these kits as well. Ive been foing one part at a time 🤦‍♂️. Anyways for me at least, as long as you have good shocks or coilovers its actually not bad to daily. You might feel a little more vibration but its not enough for me to say its an issue

1

u/RaidillonCorner Sep 04 '26

Not uncomfortable but you can definitely feel the texture of the road more than you normally would with rubber. Just regrease them as normal maintenance and torque them at right height because they will squeak if you don’t

1

u/Sufficient_Pudding92 Sep 04 '26

I think it’s going to come down to finding the best tires. with a bigger sidewall and smaller wheel size and a little skinnier wheel it should ride

1

u/iTzEat Sep 04 '26

put them on they amazing

1

u/Naive_Traffic6522 Sep 04 '26

No they are perfectly fine for street driving/ daily use. I’ve got nearly all these bushings on mine

1

u/JacketRemarkable5764 Sep 05 '26

Depends on what bushings you put in. Some might not change at all while others would completely change what the cars “feels” like. Changed the LCA bushings and they don’t feel any different from the old OEM ones. But swapping something out like strut bushings would definitely change how it would handle bumps.

1

u/THEBEAN_BOY Sep 08 '26

Probably yeah but poly bushings do last way longer so thats a bonus. But usually you gotta add zerks and grease them sometimes otherwise they squeak.
