Stiff ride question
Ok, my car has a stiff ride lol. Not what I would expect from a Lexus. I know, it's the sportier model from the company but it still rocks the inside door panels on rough roads so my question is this. Did only the sports packaged cars come with the stiffer suspension? I'm assuming so but I had to ask. Now, I know a lot about tires, but not so much about luxury tires lol. I'm a racer by nature so I got that down, but now I'm shifting gears torwards the luxury segment and I'm looking for a softer ride. The car came with some **** Fuzions in the factory size so there's that. I was also thinking of going up a tad on the profile as well to 225/50 for a touch more side wall but some people say try a grand touring type tire for more comfort. Have any of you tried this? All I see are people jockeying for an even stiffer ride which is absolutely beyond me lol.

The sport package has a stiffer suspension setup (shocks and springs), if that's what you have. Naturally, like you said, it is still a sports sedan. It isn't going to be ES pillow-like on the road. Some options would be swapping out for a non-sports package suspension setup, swap to 17's if you're equipped with 18's... You don't want to get too crazy with increasing the sidewall size, you'll throw off your speedo, shouldn't usually be a problem though.. As for tires, reviews are king for the most part. Going all-season over summer is always the better choice if you're looking for longevity/cushyness. I'd stay away from the more "sporty" all-seasons though (e.g. Michelin Pilot Sport A/S3+, although I've never really noticed them being rough riding myself, owned these for a year now. Noisy though).

Same here, I have 2011 IS250 RWD and I find the stock suspension too stiff for my liking. My friend's 2008 IS250 suspension is very nice and comfortable. I checked the numbers on shocks (both cars with factory suspension) and his 08 shocks have different numbers then my 2011.
I remember reading while ago that somewhere around 2010 Lexus stiffened up suspensions on majority of their cars hoping to achieve that "sporty handling", for more predictable stability at high speeds which is well known in German cars. There are vast number of Lexus RX drivers on this site complaining about suspensions being stiff AF in their 2010 and up vehicles.
I'd like to hear other drivers opinions on that matter.

I still can't believe how my inner trim panels rock when I hit many hard bumps at one time. I mean it's not bad, but even I can't reasonably expect a manufacturer to be able to assemble a totally rock solid interior; there's just too many parts to be able to do that.
I'll check er out though. I'll do tires first. Thinking of Pirelli P7 Cinturatos. Whaddya think? If the tire change doesn't do enough for me then I'll look for springs next.

Buy Swift springs, arguably the most comfortable and the best linear springs money can buy.

I have a brand new set in my garage, just waiting for nice weather to be installed. Swift are very conservative and don't lower your vehicle too much, that's what I like about them cause you can use them with stock shocks.

Dam... that's disappointing lol. I LOATHE car lowering lol. Not even a millimeter. True, for SOME cars it does look a little better but I am all 100% for ride quality, and want as much travel as humanly possible. I'm also going up on tire sidewall a touch too to help out the ride. I miss my '77 New Yorker's ride lol. Would you have any proven specs as to the older OEM spring rates? Some say they are indeed softer.
