Just bought a 2018 RDX base in silver with black interior. It is a certified car with only 12K miles on it. This is a trip car for my wife and I and replaces a 2009 toyota rav4 v6 which was getting long in the tooth. The Acura is certainly more luxurious and rides smoother, but does not have as much brute power and certainly does not
handle as well. The rav had the towing package with larger springs and we did later add Sach shocks to it. It cornered quite well, but did let you know when it hit a pothole. The Acura is more floaty and feels great on a smooth road, but feels like it gets a little upset when the the road gets
rough, esp. in the rear. I am wondering if helper air inserts would help...I did this in my toyota to keep the rear higher when towing and it had the side effect of helping the ride and handling too. These are the firestone things you install inside your coils and pump them up with a hand pump to
suit your ride. Anyone here done this? https://www.suspensionconnection.com...r-springs.html

 

Air bags as they are called do not seem to be a popular mod around here. I also have an Odyssey and have used them in both my current 2015 and my old 2002.
in both cases the AirLift 1000 ones were always the top choice. The Firestones ones have a reputation for springing leaks.

All this said, I doubt air lift helpers would really apply to an RDX unless you were towing. What I find is the stock rear suspension is designed for heaver loads
than (ours anyway) seems to get. It just seems bouncy. I wonder what the differences in the rear suspension are for the Honda Passport? That is how this generation of RDX lived on.

 

thanks for the reply. I heard the replacement rear kyb shocks are a good improvement in this regard. I think the the air spring inserts might give quite an improvement in theis regard too. They really helped the ride on my rav4, even when I was not towing. I agree with you about the Firestones...they started to leak on my rav4 and then became unuseable and I wasnt going to go in there and pull them out again. I almost bought a 3rd gen RDX because it had a more controlled, sporty ride, but I read horror stories about problems with the electronics and other things. . Also I like the v6 better than that turbo 4, which seem kind of strained. Hope we can get more performance mods for our generation. I always try to improve any ride I own and thats coming from a series of 9 different late model corvettes and my current vw gti.

 

I inflated my tire pressure to 38 psi for all tires and I think this made a good difference....car is still smooth on good road and feels much more compose on bumps...it glides over the better instead of thumping on them. The orig pressures were 33 front and 37 back
