A friend has a 2011 RL and is wondering what suspension mods are out there to firm up the ride a bit and flatten the handling. I've driven his car and it definitely is a more "cushy" and floaty luxury ride feeling compared to my 06, feels like Acura set it up more for comfort and tuned out a bit of the responsiveness and firmness. I do like the engine and tranny set up though, makes the car more energetic off the line.


He's not looking to lower the car much if any at all, just something to firm it up a little and reduce a bit of body roll. Was there an A-spec package offered for the 2011 models?

 

Your butt dyno doesn't jive with reality. They actually stiffened up the MMC suspension and added the thicker sway bar to reduce roll.

All of the suspensions that fit the KB1 fit the KB2, and all are documented here. There was no KB2 Aspec, but the old will fit if you can find it. It's discontinued, but it occasionally pops up on eBay. That's his best bang for his buck.

 

You could also try swapping in some H&R sport springs that will lower the car down about 1.4" but also provide a sportier and more stable ride. We have them available for $239.85 not including shipping.
