yes it has a 16mm front sway bar. Yes it will fit a 2001, but unless you are racing there is no need to go from a 24.5mm (2001) to a 16mm (2003)front sway bar. the DX, VP and HX i don't think have any sway bars so you would need to mount those.

No you can't fit a RSX or Si front sway bar. The list of current aftermarket sway bars are in the FAQ which can be found in my signature.

thicker front bar means more understeer at the limit.

understeer sucks. my friend said that i had a little bit of oversteer now that i have my rsx rear sway in, but it still feels like its understeering.

i have a 2k1 meaning 24mm front and now 19mm rear.

I have a 2k2, 21mm or 22mm (forgot what is the exact #) up front and 19mm out back. I can make my car oversteer easily even before the limit. But mash the pedal understeer is still present.

Um.... mashing the Pedal in a turn = Throttle Induced Understeer = Driver Error, not car issue.

Ease off the gas, You'll take the corner better and accelerate out of it better.

Yes, I put the front sway bar off of an '02 RSX (it was a type-s, not that it matters) onto my 04 LX. I just crawled underneath (didn't even need a jack thanks to the stock off-road suspension) and unbolted the stock sway bar. I was able to get it off without removing the exhaust by simply turning it as I pulled it out. I did the opposite with the 23mm bar, and it fits perfectly.

Did you do any thing to your rear bar? Because going from a 15.9mm to a 23 mm bar is going to cause some serious underster....

hmm interesting...I always thought the front sways from the Si and RSX were different because of the placement of the cat. Maybe they will fit the DX/LX though. hmmmm

If that bar would fit anything, it would fit the LX because there's no cat in the way. Still is interesting. You HAVE to move the exhaust on the EX BTW.

I changed the rear bar to the 19mm RSX as well. There was an immediately noticeable increase in understeer, but the handling is vastly improved. I haven't driven a 01-02 with the bigger front bar so I really don't have anything to compare it to. All I can say is that the 04's a whole lot more fun to drive with the bigger bars.

The fact that the LX has the cat on the manifold makes the install and fitment completely trouble free. The miniscule exhaust pipe is only a minor inconvience.

???? How can you say that handling has improved when you also say that you've gotten more understeer???

That would imply that the cars handling has actually gotten worse....

The handling has improved because body roll isn't as evident. Due to the decrease in body roll the tires tend to hold the road better which provides the improved traction through a turn. As for the understeer, it allows for more control over the line of travel at higher speeds. I'm not sure how it was with the previous set-up, but on the 04s there wasn't much, if any, understeer to begin with. I found at high speeds it would often oversteer with the stock stabilizer bars. Therefore, I stand by my previous statement.

I have an EX and an RSX front bar will not fit, but I checked it compared to an LX bend and it looks like it will fit an LX.

#1. Body roll means very little in the way of handling... it only really does 2 things. 1, Annoys the driver and 2 causes a bit of camber loss in the corners. Thast it. So, body roll or the lack there of does not imply a well or poorly handling car.

#2. all Understeer does is force you to go slower through the corners. Simply because it causes a car to continue going in a straight line, if you approach the cars limits. Of the 3 states a car can be in durring a turn, understeer is the safest. In regards to handling, it is THE WORST state the car can be in. (A well handling car is inherently unstable). For better handling, a car should be nutural or slightly oversteer at its limits.

So, you havent made the car handle better, youve simply made it more stable and thus more user friendly.

I can pretty much gaurentee you that if you were to test back to back on a road course between the 15.9mm/19mm combo Vs teh 25.4mm/19mm combo, your lap times would be much better with the 15.9/19..... The car would feel more unstable, but it would be handling much better.

I ran the 15.9/19 then moved to the 25.4/19 as well, the car is much more balanced and in high speed cornering you can go much faster without audible loss of traction where at similar speeds with the 15.9/19 the rear tires are reaching their traction limits making quite a bit of noise. On an autocross course I would agree the 15.9/19 would probably be faster and throwing the rear end around out there works to your advantage and as long as you are on the accelerator you can keep it under control, its not exactly the same at road course or highway speed.
