Default SE Ride Quality (And Road Noise)

How does your SE ride quality compare to other cars you've driven?

I absolutley love this car!!! but for some reason, it feels bouncy and a bit rough at times, more so than I'd expect. My old 1991 Cutlass Supreme didn't have as good of structural quality, but it handled similar, and the rough roads weren't felt as much, and I had new KYB-GR2 struts put on it last year. The struts seem to be in good shape, as there is no clunking, and they are firm when I press on them. I am thinking a tire may be out of whack, because one thing I have noticed is some bounciness, especially when braking around 40mph.

Also, I have noticed more road noise/rumbling comming from the rear of the car than I would like. Would dynamat make a noticable difference in noise levels if I were to install it under the rear seats and around the wheelwell area inside?

sounds like you might have somthing screwy with the suspension. mine started doing that after the little bracket that holds the sway bar to the frame broke.

You may have something screwy in your suspension, or the quality of the KYB struts might not be the same as OEM. I know other members have complained that their KYB struts can be a bit rough at times, and a few people have reported some "pogo" effect. Not sure if this is what you're feeling, since I haven't personally experienced it.

SE springs are supposed to be soft and bouncy. If you 'over-strut' them, you end up with an imbalanced suspension.

Your road noise is most likely your tires.

Love the ride of mine, although it'* about time for some new struts and swaybar endlinks. The only time I get annoying road noise is when it'* time for new tires.

everyone who rides in it says it rides really nice and are surprised when I tell them she'* 7 years old.

I'm guessing my SLE still has SE suspension. My car does ride a bit rougher than mom'* 300M or my old Eagle, BUT, it handles better than either (if their TC is turned off, as the Bonnie don't have TC). There is virtually no road noise, especially when I turn the radio up.

The KYB struts were on my old cutlass, the Bonneville has factory struts. This Bonneville sorta rides like my friend'* 1997 Cutlass Supreme did when it was new, sort of a more European feel I guess.

There'* also this wind howl comming from the passenger side, and I put silicone on the weatherstripping, and its still doing it, so I'll have to check that out, I think much of the noise may be comming from that.

try pushing out the top of the window while driving.. does it get worse? if so the top of the door has been bent out, likely from someone trying to open the door without keys...

it will never be perfect, but you can bend it back in while you have the door open, trial and error

Sorry, I didn't read the original post very well

Anyhow, it sounds like Andrew is on the right track. See if there'* any evidence of the door being bent or tampered with.
