I'm typing with a broken right hand, so I'll make this as brief as possible.

My IS' ride quality has become a headache. It feels sloppy over road imperfections. It clomps over potholes and stumbles over expansion joints, rattling all the while. I have Luxury Package w/ 18" wheels. I hate to sound dramatic, but the last Accord I drove handled rode imperfections more gracefully than this car (not to mention my friend's A4 w/ 19" wheels).

Anyway, not sure where I'm going with this, just wondering if anyone else is distracted by their 2IS' ride quality and if there is anything that can be done about it.

This quote from C&D (in reference to a BMW X3) basically sums up how I feel:
Thanks.

thats a 2is for you! lol

aftermarket shocks?!?!

I dont notice that bad of a right. I do have a rattle from the center speaker grill.

Maybe it is the type of tires on the car. I know Michellin's have a very good right. Maybe that is what you need to look into

Summer tires have a better ride than all seasons in summer.

my ride has been perfect...i owned a 2005 audi a4 and my lexus rides much smoother and quieter...knock on wood

It also depends on what car you're coming from.

The Accord leans towards a bit of a cruiser car, so the suspension is a bit softer compared to the Lexus, but it shouldn't be by much.

I came from an Infiniti FX35 and my 350 can only come to about 80% of the ride quality. While the two cars are in different classes, I think the IS isn't too bad considering it's a bit of a sporty car. O, I have the summer tires on my IS as well. I live in San Francisco, so road imperfections are a daily thing.

Try getting tires w/ larger sidewalls

I have the 18" wheels with the Bridgestone Turanzas and they ride very nice and quiet. Maybe you have a bad suspension componet or tire?

I have the potenza, I believe the turanza is a softer tire then mine. I had great success with Dunlops on my Z28. little louder they the Michellin but rides just as nice. Goodyears are not really good anymore for wear.

Not too many cars ride rougher then my Z28. Z28 Bilstein all the way around, poly on all suspension. It pulled a 1.05g in a lateral test!!!

Are your running winter tires? What kind of temperatures have you had around there lately? The IS feels very stiff in the cold weather but only couple more months of that and we'll be back to normal.

I ve had two IS's I had a 25o back in Nov 05 when it first came out and now a 08' 350 the ride on the IS I think is to soft and comfortable. The IS almost doesnt feel sporty if you have driven any new BMW you will understand what I am talking about. The IS has a very soft comfortable ride for a sport sedan

This car is stiff compared to Accord or Camry. I felt the same thing coming from a Camry but the power and handling are much more superior.

just get tein cs and get the edfc so you can adjust it that's what I'm doing.

i went to tein ss coilovers and the ride quality to be honest is BETTER than stock in my opinion... got in a loaner the other week and ride quality didn't appeal to me at all...

LOL +1 OF COURSE ITS BETTER, its full adjustable

My 2is rides like heaven compared to my last car. My last car was an 00 grand am gt lowered 2 inches. It hurt to ride in that thing so I can't complain about the 2is.
