I have the Comptech RSB and don't have any visible damage to the mounting points after two years. Still, I think it'll be informative to see how many people have the Comptech RSB and, of those, how many have mounting bracket damage a la this thread.

Thanks for participating!

 

No problems so far....

 

Progress, 13 moths usage + ~18,000 miles, no damage to mounting points or frame.

 

currently have stock, been thinking about getting progress since last summer as I will be installing an aftermarket exhaust. Hopefully everything goes well......

 

the progress bar is sitting in my living room.

i'm deciding whether to install or not.

 

dont have a bar yet which others have told me is pretty funny. will be getting prgress or swift when I do.

 

Of those that do report damage I think it would be very interesting to hear what kind of bushing you are running. Seems that both cases so far have used polyurthane replacements for the rubber ones that comptech comes with

 

32000 miles with a sway bar (comptech for 10, progress the rest) and no problems!

Feb 21, 2007 @ ~44k miles - Detected broken sway bar mount after clunking noise

I never heard a clunk until a few days before I found the broken mount. So I do not think the mount was broken long before I started hearing the very obvious clunking. I am very aware of "noises" and my car, even with all the mods, is pretty quiet and rarely makes strange noises.

 

I'll need to inspect the mounts this weekend before I vote in the poll. I have an 04 TSX, 5AT with the Comptech Swaybar and ES poly bushings.

 

I'm pretty sure I've had my CT bar on for over 37k miles, but I have no damage and from the looks of it, everything is 100%. All the pressure welds look fine and there is no sign of warping, stress or fracture that can be seen.

68k miles on the car
FWIW, VIN 6400, June 2003 pickup
ES Bushing: 9.5158R greaseable bushings (required bushing bracket modification)

 

No problems so far....but I just put mine on last thursday.

BTW, I have the 2nd generation CT RSB...mine came with poly bushings and not rubber bushings.

 

stock rsb.

i have the comptech rsb in my trunk. waiting to install once the weather gets better. however, given the current discussions going on right now, i'm becoming a little hesitant.

 

^ +1

I had it on my 04 for about 4k miles and had no issues with it but i am now debating about putting it on my new 06

 

Comptech w/ their rev 1 rubber bushings and no damage visible to mounts. I've had it on the car for about 1 year (18k miles). About to change to ES poly though, so this is indeed interesting.

 

I'm not sure what I'm going to do. I'm planning on installing Tein Basics on my TSX this spring and, with the increased roll resistance of those dampers, I may go ahead and reinstall the stock sway bar.

As much as I enjoy the idea of flat cornering, I'd hate to have to go through the mess of either finding someplace to weld my mounts if they break or else replace the subframe (at least $600 just in parts). The car is my daily driver and I bought it for it's reliability, I don't want to do anything that will have the car in the shop for a week.

I'm anxious to hear what the solutions were for the two people who have broken mounts.

 

my sentiments exactly!

 

I think it's the thickness of the bar that's the problem(22mm)not the type of bushes that are used.I've got an 18mm RSB on mine.Installed it when car was new,now 8 mths.later and 15000kms.later no problems.BTW i have poly bushes.

 

I updated the other thread. Essentially, I found someone who is going to MIG weld the mounts. Then, I am going back to stock. I know only 2 ppl (me and another) have had the problem, but the mod is not worth the potential problems IMO.

 

Nope, as already explained on the other thread - https://acurazine.com/forums/showthr...9&page=3&pp=25 - the bar thickness is not the concern.
Progress have tested 27mm bars of their design (no idea how that differs from OEM, Comptech, H&R, or Swift) and it was only at that thickness did they encounter issues which required beefing up the endlinks and mount points.
They have since dropped back to 24mm for the circuit cars, and 22mm for what Joe Public can buy for road use.

Where the issue resides, allegedly, is that the Comptech bar was sliding in the bush at the mounting position, instead of purely just twisting/rotating as per design.
This latteral movement meant the bar was not working to design and created higher levels of stress than intended.
Progress limit this potential by welding butts/plates on either side of the mounting D clamp, so the bar can only flex up and down or rotationally in a twisting motion.

Perhaps all that's required is to use a slightly smaller bore bush on each mounting D clamp section of the bar, so that there is less chance of the bar moving laterally.
That or a higher torque on the clamp bolts to compress the bush (whatever type), again so that it creates more friction for the bar to overcome laterally.

 

I posted this in the other thread.

Just a bit of a reality check, I did the math. There will be roughly 100,000 TSXs on the road at the end of 2007. We have 2 people with this issue constituting .002% of the future population. To potentially mitigate this issue, I think we all, with non OEM stock RSBs, should liberally (only time I'll use that word ) apply lithium grease to prevent any binding between the bushings and the bar. This should eliminate concerns around side to side movement of the bar. Just a thought.

 

I have 80,000K on the Comptech Bar and the only problems I've run into were squeaky bushings. Since I switched to white lithium grease, I haven't heard a sound in 10,000+K.

 

Makes me wonder if the bars might be binding up on the ES poly bushings.

 

That's what I'm thinking as well... and since my poly bushings are creaking/squeaking like freakin' crazy in this cold weather (since about November ), I think I'm going to get a plethore of white lithium grease in there ASAP. Next oil change is in a week or two -- I'll do it at that time.

 

This is one benefit I have having the zerk fittings on the RSB bushings. But the install was a PITA which is why I don't recommend them.

 

I just posted this in the other thread on the Ct way bar in addition to Moda's suggestion, i think as long as you keep the bushings properly lubricated, you shouldn't have too much of an issues. If the bushings stay lubed, the bar will be allowed to slide easier and create the motion its suppose to without adding a lot of additional stress to the mounts.

Eric - Lube the hell out of it and you should be fine Hope things are going well for you too....haven't talked to ya in awhile!!

 

I'm no engineer, but I don't believe it's friction with the poly bushings that is tearing the steel mounts. I think it's the forces placed on those points by the very much stiffer bar. I don't know, I like the effect of the Comptech bar a lot, but I know I'll totally kick myself if I crawl under there in a year or two (or three or four) and a mount is broken.

I'm torn (no pun intended)!

 

^^ I'm with Pete, and I am an engineer, just the wrong kind to know a lot about this. One thing I do know is that my rear suspension is creaking whenever I go over speedbumps (long suspension travel). It also started when the weather got cold, around December. I originally thought that one of my rear shock/struts went bad but now I'm thinking that it could very well be the swaybar vs. bushing contact.

 

 

That's exactly what I'm experiencing, and all it requires is lubrication.

As for going back to stock, I don't think I ever will w/ this. The mod is too fun and too noticeable to go back, and the likelihood of the mount(s) breaking is VERY slim. People have been running these bars for how long now? And just recently we've only heard of 2 incidents about it happening. That's very, very slim chances. I'll take those odds.

 

Just less than 100,000k on Comptech RSB with Energy Poly Bushings with grease fittings. No problems and no squeeks...I use low temperature lithium grease.

 

I have the ES bushings...

 

anyone with the other bars getting problems? Im contemplating getting a comptech rsb, but if theres no difference i'd just get a prog bar if they don't have any problems yet.

 

Comptech is going out of business, it might make sense to go w/ Progress regardless

 

I'm leaning towards keeping the Comptech RSB but keeping an eye on the situation.

 

I think a lot to do with this problem is the thickness(22mm) of the bar.If you are concerned that this may happen to you i suggest you go with an 18mm RSB(which is what i have).

 

hows the feel on a 18 mm?

 

Fine.Big dif.from the OEM one(although i haven't driven on a 22mm).I do have Eibach/Bilstein suspension which does help in the handling department.
