Just trying to take a count here of the interest for this? maybe eibach can make a small batch to go with the lowering springs? I know I would definitely buy a set, ive done this to all my cars ive owned, in fact this is the first mode I do.

Honestly, I used to do this mod, but I am no longer interested in "messing" with what the manufacturer has done in regards to R&D. The best compromise of ride handling etc. I'm good just as it is, the RDX is a fine ride for me.
Obviously, not all agree, which is great!

No need to retype essentially the same words.

Not interested.

Nor Konis and a free flow exhaust.

Or, dare I say it...lowering springs. (Sorry Padre!)

I don’t need sway bars or headers.

Maybe to a rear sway bar - wouldn't mind slightly perkier turn-in but not a ton.

I'm more interested in better shocks as I find the damping to be not good enough (too stiff legged) - a set of Koni sports would sure be nice.

Are you in an A-spec? I'm wondering if your problem isn't the Goodyear tires. If my Advance turned in any more crisply I'd be spinning donuts.

As for stiffer sway bars, I went that route long ago with my '84 Prelude, along with wider, lower profile wheels and tires, and it cornered like it was on rails until one of the sway bar brackets broke from the added stress. This was within the car's first couple years of life. I vaguely recall getting an indy shop to weld something near the gas tank to fix it. They drained the tank, stuffed a couple rags in the opening, and went at it. I didn't watch.

Also, I seem to recall the steering got really heavy after the mod, but that might have been from wider wheels and/or inappropriate offset. I didn't have a clue what I was doing at the time. Pretty much I still don't, so I try to buy well engineered cars that suit my needs and resist the urge to screw them up.

I don’t know about sway bars specifically, but I don’t buy into this idea that the “manufacturer has achieved the best balance” anymore. It’s clear that most cars come with inherent compromises. Acura perhaps more so than other luxury brands if for no other reason than they are not offered with a huge list of expensive options. With the RDX it’s basically package one, package two, or package three. That keeps costs down and makes it a value, but it also means that there are improvements that could have been made that we’re not because they Acura’s neat little boxes. So those improvements have to come from the aftermarket.

So yeah, bring on the sway bars, ECU tune, catback exhaust, high flow fuel pumps, down pipes, inter coolers and all that. Until there’s a factory tuner option, there’s Graham Rahal!

I think you're buying the wrong brand of car. You would be happier in a Dodge. Sadly, they don't make the Dart anymore, but there's gotta be something suitable for your destructive tendencies.

I bought the Advanced model to get the upgraded suspension among other things. This car handles better than I drive so why would I want to modify it and spend more money? If I wanted better handling I would have bought the "Z".

Waetherman

Ok boomer. :P

Yeah, I'm in an A-Spec and the tires are indeed hot garbage (will replace them next Spring when I'm driving more). I generally like pretty pointy front ends on my cars - my Miatas and my TSX all got stiffer rears bar. I'm sure if I were driving something mid engined that wouldn't make the mod but for a FWD car I definitely want a bit of extra rotation on turn in.

Wander

My '85 MR-2 ( mid-engine ) got Koni adjustable racing shocks, but no sway bar mod as I recall. Unassisted steering cuz the front end only had to hold up my feet and the spare tire under the hood, so its response was pretty sharp. Basically a street legal go-kart.

No fancy wheels on this one, either, cuz it was a replacement for the Prelude that got stolen and totaled because of the flashy wheels. Sob. It died much too young.

But the MR-2 was absolutely useless in the snow. I recall trying to make it home to the burbs in Boston after a snowstorm and I couldn't make the darn thing track a sweeping banked curve on a neighborhood street, so I finally flipped it around and drove backwards for about a quarter mile, with the tail angled about 30° up the slope. No joke. I probably still had MN license plates, so no one got too worked up about it. Boston drivers are just a different kind of crazy. And the RWD BMWs weren't going anywhere.

With SH-AWD turn-in comes courtesy of your right foot, especially in sweepers. Just like your RWD Miatas. Dunno what FWD RDX feels like.

sonyfever

The car in A-spec + RS-A tires form needs more front-end grip more than anything else. I also think once the car gets over the initial understeer stage, the car actually rotates quite well, and if you make good use of SH-AWD, the factory setting kind of makes sense, because reducing the rear grip (yes that is what stiffer RSB does) is going to make the car too tail-happy for those unguarded.

sonyfever

I would sign up for a set of KW or any mono-tube ones....

I added the Progress RSB to my 08 RDX along with Eibach Springs. I've didn't notice a big improvement in cornering on the RDX like I did with my 06 TSX with A-Spec suspension+Progress RSB. I think the reason why is because sh-awd was doing its job. The difference I felt on my RDX was when I needed to corner without benefit of sh-awd. No engine power and OEM set-up and the RDX is close to a 2 ton top heavy CUV in the corners. Adding Eibach and Progress reduced body roll, squat, dive, and I was able to take corners at a much higher entry speeds off engine power. Higher entry speed, less power needed to maintain speed in/out of corner, and I my speed stays about the same without using the brakes or sh-awd as much.

Eibach springs might not work with the Adv RDX; but, the Progress RSB+active dampers might yield the same results folks will have with non-active damper+Eibach Springs+Progress RSB RDXs. I would do this mod if I had a 3rd Gen RDX because I like pushing the performance envelop.

sonyfever

Thanks for sharing. Yeah off-throttle is a void for SH-AWD, but 3G RDX has agile handling assist which uses the brake to assist turn in. It is effective when steering input is applied gradually, but yeah when pushed hard the car can feel out of shape in the initial phase.

11 no, and 1 yes? Hey guys, where's your sense of adventure??

Madd Dog

Most of the bars I frequent for an evening must be sway bars, considering my gait when I walk out of them.

Midnight Mystery

Funny to see this now because I just ordered the RSB for my car. LOL

Rocket_man

I upgraded the RSB on my TSX and it did improved the handling. Then I too broke one of the end link brackets supports from the underbody. It wasn't hard to find a body shop to weld things back together, but it is a risk you should consider if you want to add a new (or stiffer) RSB to a suspension. The design of the attachment points may not be up to the new stress. After I had mine repaired it did not recur.

lil12002

RSB for the RDX?

Midnight Mystery

LOL. No. I have an RDX, but I bought the RSB for my Accord.

I was just noting that a RSB thread was posted when I was ordering a RSB for my car.

The RDX has a plenty firm suspension stock and oversteers easily as is.
