im thinking about upgrading the rear sway bar to a 22mm one, but is the tsx subframe strong enough to support this thickness? on older hondas, integras and civics needed something called the asr subframe brace to prevent tearing of the subframe.

 

I've had my bar on for over a year and it's still fine.

On other note, from what I was told by my mechanic that the sway bar was a waste of money because the endlink mount were the same thickness as the stock one.

 

its going to be fine. my rsx runs a 25mm rear sway and i think 06-07 civic si's run 27mm rear sways, correct me if im wrong.

 

The TSX is a bigger (better) car than Civics and Integras. We've been running 22mm sways for years with no issues. No need for Beaks or ASR type kits.

We've got adjustable Progress bars in stock BTW.

Be sure to upgrade your suspension close to the same time as well, else you're increasing your risk of breaking the RSB mounts. There was a thread of a couple people:

I have a 22mm Progress RSB and it works perfectly.

 

The difference before/after the swaybar installation is night and day, even with the stock endlinks. Your mechanic doesn't know much about physics.

 

~1 year since comptech rsb install, and no problems.

but ya, i think i read one case about broken bushing mounts...

 

For real. Unless the end link is so insubstantial that is is deflecting from the force being applied by the sway bar, it's all you need. Your end links don't look like horse shoes do they? I'd probably be looking for a less stupid mechanic if I were you.

 

I'd say just stay away from using the urethane bushings. I was one of those people with the cracked sub-frame.

 

so, is there any definitive answer to this? i'm seriously looking to get the comptech or progress rsb but am worried about the few instances of cracking sub-frames...

 

I should be getting my Progress RSB tomorrow, looking forward to feel the difference. My car has stock suspension set-up, and I don't plan to switch anytime soon. I heard alot of issues with urethane bushings, mostly about how much it squeeks. I guess I'll just have to see.
