Best suspension mods for Altima 2.5 sedan

[bb700092]

I have an 09 Altima 2.5 SL sedan and would like to improve its handling. I do not want to feel every crack and pothole in the road; infact, the stock feel of the road is pretty nice (to me).

However, I do want more stability i.e. less sway in windy highways or when a semi passes by and tighter cornering. I do not go to the track or autocross but would like to feel a difference in normal day to day driving.

I need some suggestion for the best proven mods for the money to improve handling. Thanks much in advance.

Also, to guys who have driven both the 2.5 and 3.5SR, is there any difference? The 3.5SR is supposed to have a sport-tuned suspension.

get a rear sway bar, you'll feel the difference right away going through the corners. check out racinglineperformance.com and see their stuff. and there shouldn't be any difference between the 2.5 and 3.5sr, pretty sure they have the same suspension other than maybe some stiffer springs cause it's a heavier car

My car is all over the place at highway speeds of 50 mph or more. It is extremely difficult to keep the car in a straight line even if it is not so windy. At 70 mph or more, it is so bad that the car seems to go out of control unless I hold the steering wheel very tightly with both my hands. I went to a Nissan dealer and they did road hunter force balancing of all wheels and front and rear alignment but nothing has improved.

Note that there are no vibrations as such.

I strongly feel there is some problem with the steering column/rack. Any suggestion will be greatly appreciated.

My goal with suspension mods is to fix the above problem. Do you think it will be fixed or is there something else going on?

Did the dealer check for recalls? There was a recall for front strut insulators.From http://www.recalls.gov/nhtsa.html, it's NHTSA campaign ID Number 09V358000.Other than that, it might be tires, or something loose in the suspension (ball jointor tie rod ends). Maybe try a different alignment setting.

Hi bb700092, I had the same problem with my 2009 2.5S Sedan. Went to the dealership with no luck of getting the problem solved. Replaced my shocks/struts with new KYB's and all those problems went away. My car is straght and very predictable now. This might be your problem as well.
