G37s oem suspension

Hey, I have an 08 g37s with stock sport suspension, my tires are 245 front 275 rear. My question is that is it normal for the the ride quality to be so rough? I mean extremely rough. I can feel every bumps and cracks on the road as if the shocks/springs doesn't absorb the impact. I took it to the dealer and they said that it's normal and that it might cause by my tires siZe not being oem size. Is that true?

If you went down in sidewall size then yes, you're going to feel bumps more compared to the OEM setup. I'm assuming you have 245/40 in the front and 275/35 in the rear.

Aspect ratio might be less but the sidewall is still the same height.
Ive been checking tire diameters for a future purchase to his size myself.

To the OP what tire brand, some do have stiffer sidewalls, and harder rubber compound.
Also check your tire pressures.

could it be that the tire is old and almost bald? You should upgrade to the Tanabe coilovers, maybe that will be a lot better for you.

Are you kidding? Dude, if you want the ride on rails cornering, you're going to feel the bumps. It's like tires... you can have soft rubber that grips and wears out in 20k miles, or you can have tires that last 60k miles but don't grip.

You can't have both. You want a smooth as silk ride, buy a Cadillac.

I have to agree.

I have the sport suspension with tanabe spring and it rides fine to me. The think is, ride harshness is very subjective so in all reality we can't really help you when it come to the way the suspension feels to you.

Sure as hell you can have both.... The G37s is a small wheelbase car and its ridiculous rough riding is overkill and there is no excuse for it to be that way. Inifiniti just went overboard on it. Too harsh a suspension can hurt handling on any car.

Sport tuned system doesn't deliever what exactly? Define what you think sport suspension means.

Its not a soft/cadi like ride, its a sport suspension.

Handling on the car is exceptional and IMO characteristic of what most sport suspensions feel like. Could it be alittle softer, maybe. I personally like it just the way it is.

I went frome oem 19" to Vossen cv1 with Vredestein 20" and let me tell ya
the dealer is right. My G has gone from being a comfy luxury coupe to a freaking race car. Handling is very precise and way more responsive now but i can tell you the harshness of the road feels about 25% more than stockies. In fact when Vossen releases their new 19" later this summer i'm realy considering going back to 19". Unless somebody can confirm that coilovers can smooth this out.
