Yes you heard to right. Replace 2.4 springs with 2.2 springs. I want my car to be a more comfortable daily driver but keep that 2.4 engine. I would imagine that it wouldn't be to difficult to have someone trade springs with me. Has anyone does this. If so did ride comfort improve. I would be leaving the 2.4 ss larger lower control arms in however. It would likely just be a strut/spring swap. Should fit no prob. right. Same chassis, same connecting point and dimensions. Just different spring rate. right?

 

i cant for the life of me figure out why???

 

your not going to gain much from it. when i went from the 2.2 springs to the ssc springs i didn't see much loss of ride quality. I don't think you'll gain a thing.

 

you wont notice anything lol

 

buy the eibach pro kit...my 2.4 rides 100% better than the stock springs...and it's lowered but not a ton.

 

Eiback eh. I've heard some good things about them. It terms of riding better, could you be more specific. Are we looking at smoother, better handling, firmer? And you mentioned lowered ride height? Is not the ride stiffer once lowered? What about bottoming out on the occassional monster pot hole? I'm in the Northeast after all, the roads get worse every year...Damn plows
I checked prices out. Doesn't seem to bad. Wouldn't I run into trouble with alignment? Ie: camber, toe, that sort of thing?

 

If you switched to 16" or even 15" rims with a taller profile tire you would improve your ride. There is probably a few people here that would love to trade there 16" for your 17".

all of the above...it's stiffer in corners...smoother over bumps and daily driving. the handling is all around better. the Prokit doesn't drop the 2.4 much...it just evens out the body ( i have yet to bottom out, and i live in western ny. i drive on some of the worst roads ever). the drop isn't enough that you'd have to have an alignment but i would suggest it. they pretty much drop you to the height of a stock ss/sc, with a better all around feel.

 

I doubt 15's would clear the brakes. 16's might. But i'd go with the Eibachs and leave the tires/wheels alone.

 

please dont do this...you will not be able to notice much so IMO its just not worth it. if your looking to get a better ride just get the eibachs they will make the ride better and your car look better

 

Good point LewiSS, I didn't think about that.
Dennis

 

Eibachs are sounding better. I was eyeing the balt and I do think she would look good 1" lower. Close that fender gap a little bit. Time to pull out the old spring compressor and get to work, some time anyway.

 

Our Cobalts will never ride like a Deville, sorry man. The Eibach's will improve the feel but all drop springs are a little rougher feeling then the stockers are. So if you looking for a smooth riding Balt your best bet would be getting rid of your factory 17's in favor of some 16's. The taller sidewalls give a smother ride. LewiSS is right, 15's will not clear the calipers, without some grinding that is.

 

I run on Eibach Sportlines, and I find that the ride quality is 100x better on these springs then the stockers.
While it is true that you can feel more vibrations from the divits and cracks in the road, I find it to be a smoother ride over them. With the stockers, I found the ride very bouncy, so not only did you get the initial bump, but several afterward as well... On the sportlines, you get the initial bump, but then nothing and it's smooth again.

That and there is basically no body roll what so every in daily start&stop of highway driving.

 

Thats funny. i dont' get the bouncy effect with my stockers. Maybe because its fairly new still . 1700miles

 

thats what i had...i'd go over 1 set of railroad tracks and it would feel like i went over 4. i hated it but now that i have the prokit, 1 bump and that's it. love em'.

 

Try dropping your tire pressure by 3 psi, and if that makes it good enough, get some 65 series tires to reaplace yours.

Running your tires low will reduce bumps, but will also reduce tire life and will increase tire heat.

 

I'll try that. I'm worried about vibration though. Whent he car was delivered 3 tires were 10 psr low and one was 8 and it vibrated a lot at 45mph and aboce. Then again were only talkin 3 psi. i'll give it a try. prob wont effect mpg much. When I put the extra 10 psi in to there recommend 35 psi, my mpg only went up about 2 mpg. Thanks for the tip. Im gonna stay away from 65 profile. Yuck. That would be maybe a 15 inch rim and I heard rumor that the SS brakes wont clear smaller than 16. One day there will be a suspension that handles well and is also luxury. I here BOSE. yes BOSE is coming out with some funky electronic suspension that does just that. For real do a search.

 

Don't ever let them get 10psi low. You are taking a BIG risk if they are that low. If you keep your tires 3 psi low, they will wear faster, maybe lose about 5000 mi of life of the tire. If you let your tires get too low, you risk tread seperation like the firestones on explores several years ago.

Don't you have 55 series tires right now? 65 series would only be about 1/2" taller. You should be able to find 65 series tires that fit the 17 in rims that you have. Just get the numbers from your tires (215 55 R17, something like that) and look for some that have the middle number 65 and the others matching your current tires.

 

thats stupiest thing i heard

 

I think its just you.

 

lol ^ i think that made my day.

 

i have 50 profile stock (205/50/R17). i never put the tires 10 psi low myslef. Lazy dealership never checked them before delivering the car. Putting 65 series on stock rims. That would for sure mess up the speedo and probably cause so scraping in the fender well.

 

I don't think that it would scrape in the wells, the SS/SC has an option for 18" wheels, and they don't scrape. Yes, you would have to get the computer flashed to correct the speedo. Can't you get HP tuners?

Mine were down 5 psi when I picked mine up, felt like it floated around corners. Now back up to 30psi and it grips in the corners.
