Any cu2 Owner here with the 4th gens tl 52300-tk4-A02 19mm sway bar or tl-awd 52300-TK5-A02 20mm Rsb !

 

Anybody

 

Not sure if any of those are direct swap parts or will even fit, but for the hassle, might as well get the 22mm Progress or 19mm ST RSB's.

 

Someone accord Guys are using These ^^+or using our tsx17mm rsb ;

So in my head i think im good!

 

Nice thing about an OEM RSB solution is you probably won't need to bore out the original mounting point holes. Of course, this is because the bar isn't as thick as the Progress one, but should still be a worthy upgrade nonetheless!

 

Any reason why you don't want the Progress RSB? The drilling is incredibly easy and you can just paint the widened mounting holes to prevent rust.

 

Well the TL rsb 19mm is $36 (hard to beat )
TL awd rsb 20mm between $54-114
Progress rsb is $180




First is price
second maybe the balance without upgrading the front also ???

 

Changing the front one would be an absolute pain and mostly pointless anyways. I forgot how thick the progress rsb is but honestly i regret not buying the even thicker one.

 

The even thicker one requires a change that is much more extensive than boring out the mounting point holes (chassis drilling). That, and it's pretty costly. It's the Mid-Ohio spec one. I believe the only person who had it on this forum was Maiku, and he sold it not too long ago when he parted out his mods.

 

Standard Progress RSB for the CU2 is 22mm. Mid-Ohio spec is 25mm

 

22mm and 25mm

I ran the calculations of how much stiffer each were over stock. Its not linear so the 22 is much more than OEM 19, and the 25 is much more than 22.

I'll see if I can dig them up.

 

The Rear ear OEM tsx cu2 is 17mm right not 19 MM!?

 

^^^ yeah, 17mm is probably right. I wrote that up quick without checking.

 

Agreed. Got the progress, the car handles very well.

 

Ok, no luck finding my calcs but the general rule of thumb I remember was with regards to comparing the relative sway bar stiffness. Since these are basically back-of-the-envelope calculations, there are some assumptions made:
So, general rule of thumb is that stiffness increases to the fourth power of diameter. This allows us to compare the relative stiffness of the bars. To make things easy, we'll ignore units and just treat the calcs as dimensionless units:
Now for relative comparisons:
What's that all mean? Well, ignoring everything else, we can see that replacing the OEM bar with a 22mm unit will have a big change. Going to the 25mm unit will have an even bigger change. But going from the 22mm to 25mm unit will not yield as dramatic a change. This all ignores additional stress placed on other parts of the system, etc.

For my money, on a DD with only spirited on-road driving, the 22mm unit is the way to go. YMMV.

 

I went with the TL 19mm ; price is hard to beat...
I also went with 19mm Moog sway bar bushing since it Comes with à bracket which allow me to clear the subframe!

 

Hey Itr, how was the install? Direct plug and play? The Accord guys say they have some chassis rub.

Boredom makes me research car parts. Found the TL SH-AWD 20mm + bushings for around $65.00 bucks. Way cheap. Just need to see how rusted my endlinks are.

 

If u get the moog universal bushing it'll clear , the bushing is like the polybushing kit just better ,they dont make noise or need endless greasing ,thebraket have a elongated hole so u can pull the sway backward a bit to clear !
they are cheap , but u need new hardware not a big deal >
Ill post pics soon !

 

I couldnt find the tl awd rsb20mm for less than $150 so i went with the 19mm


Also the 20 mm tl awd rsb is Hallow not SOLID so realy in my opinion the 19mm is the best bang for the buck !

 

I have a TL SH AWD buddy who "price matched" the lowest pricing I could find online lol.

I called Bernardi Honda. They advertise part #52300-TK5-A02 with a Google search for the low low, but it's false. You have to purchase it through their Acura store, which has it at $100+.

Btw ... How much of a difference does it make going from 17mm to 19mm? Enough to warrant doing the swap?

 

17 -> 19 is about 56% stiffer (1.56x stiffer than stock) for a solid bar.

 

At bernardi the 19 mm rsb was $46 if i remember right for that price i'ts great and it's solid ,the 20 mm rsb is not !


Personally that with my 19hfp pds10 +koni + should be just what i need !
