What's the different in OEM suspension and OEM Sport Suspension? Does it make much differences? Is it worth it?

you have to drive them both and see for yourself. People who have it will say it's worth it. and the people who don't will say to skip it.

If you plan to lower your car then buy a car with out it. The dampers on the sport suspension wouldn't hold up very long to a stiff lowered spring set. you would end up buying the dampers along with the lowered springs anyway.

I drove both before I purchased my '04 35S. Only diff was in the lateral stering response and body roll. Ride was about the same in both. Imo there's not that much diff...both handle great.

I'm not planing to lower my car cause from my home to work there are about 10 speed bumps each way. So, my other question will be does the Sport suspension package actuall comes with different shock and springs? Or just the springs? If its just the springs then I guess it not worth buying it cause I can find a decent combo with $500.00

I believe the sport suspension comes with the Aero package,
rear spoiler with underbody diffusers. If you want those, you must
get the sports suspension also. The cost to add the rear spoiler and
underbody diffusers after the sale is very costly, like over $1000.

From my rides in both....the sports suspension has shocks with diff valving and rebound setups and the springs are a little stiffer...but not by much. Drive em both.....I'm a "mature" gentleman who likes the feel of the sports package. It rides good too..........

website says this
Sport-tuned shock absorbers and springs
17-inch 5-spoke aluminum-alloy sport wheels
215/55R17 W-rated high-performance Michelin tires

Basically it's different shock absorbers and springs and you get the 5-spoke wheels with the W-rated high-performance tires

Cato.......what did the grounding kit do for you??

It's all documented in the Hypergounding thread. First thing I noticed
was that my fuel gague started reading consistent. It starts quicker.
Low speed driving is WAY smoother. It looks cool, like from Fast and
Furious. My 5AT shifting was quicker. Ya de ya de ya....

cato, the sport-suspension package does not come with the Aero Package, but it is a pre-requisite. The Aero Package is about $550, I think, if you want it as an option.

Yup, that is what I was inferring.......

Since the sport suspension now comes standard on the 6MT, I see little choice if you want a real sport sedan. Think Lexus vs. BMW. The base suspension feels like a Lexus, the Sport like a Bimmer, (sort of!)

Personally I would have bought something else if I had to settle for the base suspension. I would not have trusted an aftermarket set up to fix the base set up in my mind. It was too vague feeling to my tastes. Now, with the sport suspension, if I decide to make improvements, (most likely sway bars,) I know I have a more than satisfactory starting point from which to build.

As stated the sport sedans suspension uses stiffer springs and stiffer sturts. And a simple test drive will show the differences. Yet, if you have a non sport longer than just a test drive, vast differences come up, when compaired to the sport suspended car. I specifically requested non sport loaners on both occations that I had a oppurtinity to be given a loaner car, just so I could chime in with a full evaluation review for this type of post. Also by not having a sales person next to me I was able to push the car to the limits whenever it pleased me as to explore differences their as well.

1. The non sports priority is to deliver a softer ride than the sport, which is does do. The non sport is happiest when driven up to around 75% of the whole cars handling limits. I think most all non sport owners are content with this and they most likely did not care for the sports firmer ride or they knew in advance that a non sport was simply the right choice from the start. Its all about what you want out of your car.

2. The overwhelming sensation with the non sport is that the car is underdampened. On roads with allot of illregularities the suspension gets way to busy dealing with those illregularities. Also that lack in dampening and or spring power makes for allot of weight transfer issues. Getting on or off the gas causes noticeable in the suspensions attitude. And sudden applications of the brakes, also causes excess weight transfer. And, to the point, NEVER run it's sturts with lowering springs. Just because their are several lowering spirngs that aren't much stiffer than stock springs is not enough to allow for the non sports lack in dampening power.


3. Handling at the limit. When pushed to the limit the non sport will step the rear end out all to easily. Simply letting off the gas does not cause a normal raining in of the back ends step out. It takes awhile for the backend to come back in line. Making for a unwelcome experience when trying to push the car on a regular basis, very much a kill joy. And those underdampend struts come up as well. They numb down the cars feel and slow down it's ability to handle quick transitions effectively. Again, diminishing the driving experience.


The sport is not perfect on the weight transfer issues, but it is allot better in that respect. And it does not suffer from the non sports rear step out behavior. I didn't really see a difference in either cars ability to apply power as early when exiting corners when cornering loads ease up as both would spin the inside tire at about the same point.

So is going to a sport suspension worth it to a non sport driver? Depends on how you feel about the differences I mention and what your priorties are for your car.

I just sold my sport suspension to a non sport owner. As part of the deal, I am getting his non sport suspension in return. As soon as I can, I will be getting the spring rates off those springs. Then, we will know the factual differences between the spring rates for the sport and the non sport.

Nice little write up.
I'd be very curious as to the acutal spring rate number of the two setups. (numbers for the shocks too would be nice). Are you having them measured? or were you simply refering to it qualitatively by driving w. them?

Gsedan35,

An excellent analysis. I concur. I have the sport suspension and have also driven a non-sport loaner G35 Sedan. IMO the non-sport suspension provides a soft "luxury" ride.
