Looking for softer ride

Remember tires act as springs and have a sidewall stiffness [depending on PSI] of 10 times stiffer than coil springs. Two springs in series are lower than the lowest in rate, so tires reduce wheel rate stiffness to the road by ~ 10%.
A different tire with a larger sidewall ratio can emmulate a 10-15% softer spring.
By 40k I would think the shocks are weak compared to brand new [especially in rebound/expansion stiffness].

G35Halo, do you have 17" wheels? If not, try stepping down to 17" wheels and tires. I have a set of 17s and the stock 18s for my coupe, and the ride is much smoother with the 17s, though I prefer the ride on the 18s, but that's just me. You'd save $ when you need tires. If you already have 17's, also consider the type of tire you have. A stiff sidewall will of course make the ride harsher and a touring tire would give a better ride. Some tire places will let you test drive a set of tires and take them back (for an exchange) if you don't like them. Just a couple ideas.

Going to 17's should help it you are using anything bigger. Also the speed rating of the tire will affect the ride quality. Try V-rated or even H rated tires if you are using a tire rated higher than V. They V and H rated tires have a softer sidewall. The stiffer sidewall on a high speed rated tires also adds to the harshness of the ride.

My 03.5 G35 sedan has the "sport" package. What are my best options to accomplish a more plush ride with regards to price and effectiveness?
Thanks.

I have the standard suspension on my 2003 coupe. 17" wheels. When OEM Goodyear Eagle RS-As wore at inside of rear tires by 35K miles I switched to Goodyear Eagle ResponsEdges and ride improved somewhat.
You could try an H-rated (to 140 mph constant) Touring tire like the Goodyear Triple-Tred which I see fitted on many a BMW 5-er or MB E-class as OEM replacements. Or a Bridgestone Turanza Serenity.
Yet I am wondering if a change to KYB Excels will SIGNIFICANTLY improve ride compliance over my OEMs at 56K miles.
What do you say Q45 tech?
