Can someone tell me on the IS350 what is the difference with the X package suspension vs the regular IS350. I was told that it is a little lower than the luxury suspension and the struts are valved different, but can someone actually confirm this.

Yes, its a little lower in the front.

Not sure about the struts...

So the springs are different but the struts are the same?

X package and sport package is the same suspension, different (stiffer) shocks, as well as front springs 10mm lower in front.

To me it is the perfect suspension. The regular IS suspension is a little soft my taste. My two prior cars were a 2004 Honda S2000 and 1995 BMW M3. Those suspensions were too hard. The X-pack is a nice compromise. The steering is also quicker.

I am thinking the F-Sport suspension is just too low and rough for the roads up here in the Northwest. Anyone interested in trading their stock suspension for my F-Sport suspension?

Not the steering ratio, is it?....... Or do you just mean turn-in?........

Last month I had an IS-F as a loaner. The ride was too firm. I thought I would love the F but I was glad to get back into my car with the X pac. My wife felt the same way.

Don't know where you got hat information from. It's already been confirmed that the steering components on both cars are exactly the same. Even the steering ecu is the same. With a slightly lower and stiffer front spring, it may feel a bit quicker but it's not because of quicker ratio steering.

IS-SV

I think he's just saying the turn-in feel is quicker, probably the result of the firmer suspension and low profile tires/18" wheels.

My bad on the steering although it does feel more connected.

Sorry for the confusion.

X-pac rocks!
