My newly purchased cobalt ss/tc came with a set of H&R springs, and to be honest, its a little rough for me from a daily driver standpoint with our crappy roads here in KC MO. Does anyone have any recommendations for a different spring that will get me closer to stock ride quality with some form of lowering retained? I don't need it to be as low as the H&R's sit but do not want to lift it back up to stock level. Any input is appreciated, especially if there is anyone out there that had the same predicament as me or has swapped from an H&R setup to anything else.

You would sell twice the amount of springs if you would just lower the ride height of your springs by about 1/4 to 1/2 an inch.

i doubt a 1/4 inch will double sales doncha know? The v2 and seq. at the rear will touch the fender liners as it if you have a load on, and the whole deal is performance and durability not drop. so we changed the config once from v.1 on and I dont see me doing it again to tell the truth. We are always testing ideas even now with Hyperco, I have sent in some springs off my car to review and we are looking at HHR specific rears ( 300 lbs heavier at the rear. So never say never.... but I dont have the magic bullet at the moment to make it lower and maintain handling balance and performance, and life time warranty. We have looked at the silicone spring wire inventory looking for a wire to do more.....................but......

Have you changed the YYZ's ride height since the last time I saw them? When I was buying my CM springs the YYZ's were only about a 1/4-1/2 lower from stock anyway.

The ride height you are thinking of is from the version 1. Version 2 on has been a decent bit lower than v1. I switched from settled sportlines to yyz v.3. Yyzs are approximately 1/4 inch higher in front compared to sportlines, 3/4 inch higher in back.

Having a hard time finding reliable numbers for sportline drop. But my estimated guess compared to stock, front will be 1 - 1 1/4 in lower and rear lowers 5/8 - 3/4 in.

Love these springs, first lowering spring that drives comparably to a stock car, and doesn't bottom out like sportlines do. Replaced with struts and shocks and don't plan on touching suspension again.

People who ride with me are impressed how well it rides for being lowered. Ya more low is sexier, but for a dd and not having to cringe over every bump, yyz is the best option for me. Not to mention its arguably the best performance set up and is the only progressive spring other than the stock rears.

This may have already been answered but I can't find it so here is my question...

I am installing a set of Eibach sportlines on an '09 cobalt SS TC. It has brand new OE shocks and struts. (I am also installing the powell racing control arms with the better CABS, & I already have the eibach sway bars installed with powergrid adjustable end links) anmd before anyone ask this car is mostly stage 3 and has adjustable camber bolts.

My real question is should I be running different shocks and struts? and if so which ones should I be running using the sportline lowering springs? The intentions of this car is for both street and track use.

Sportlines honestly aren't going to be your best options for lowering springs if your intention is to track your car, many complain they are too soft. Nevertheless the standard TC FE5 shocks are quite good, but the common go-to upgrade would be Koni Yellow shocks. The stock struts will probably be fine as long as they are in good condition.

doubt they make them anymore, grab SSC springs from zzperformance.com same height decent ride too $200-225 I think.

With lowering springs that are too soft, handling is worse and they will kill the struts shocks in a year or so... Ask me how I know. TC struts are great but when you lowering the car over 1" with bouncy springs the rear shocks just have too much travel and it will cause them to leak over time.

Ok thank you got them ordered!

One brand that I didn't see listed would have to be Canuckmotorsports.com
I plan on getting a set sometime in the future to see what they look like, but You definitely did a lot of work in finding all of the ones that are posted already so good job.

I had them... They have very soft spring rates, and cause the car to slam on uneven pavement.

From my experience with them. Keep looking, and researching other springs.

My cm springs have never done that ^ and I have had them almost 4 years. I've basically went off roading with them multiple times lol

Rduncanss06

I ended up going with cm springs seem to ride about like stock and is about the cheapest I found

You don't have crappy roads like we do in PA.

I loved my CM's! And our roads here in Michigan are quite atrocious. I never had any slamming problems, and ride was great. Drop just wasn't enough haha.

I Still dunno if or when I'll upgrade my suspension since I'm about to be upgrading to the ZZP Stage 3 kit, but the roads here in WV are bad to where some gravel roads are literally smoother and easier to drive on than blacktop. Other than that, I just think that every car will have it's own way of handling the road, so not every car will be the same. I had a 93 Z24 and the only place that had springs was CM, and definitely cheaper than most other brands out there. I'll probably still consider getting them and if they don't ride the way I like then move on to a different set.

After going from the super soft spring rates of CM springs to actual performance springs, the CMs don't even compare. I'm very in tune with my car, and I'm not exaggerating when I say they were terrible on uneven pavement. I also, have an upgraded FE5 suspension which handles lowering springs better, and they still slammed. The drop they provided was nice for what I wanted, because they still provided a raked look, but ride & handling was no where near as good as the springs I have now.

Hey, don't get me wrong, they are decent springs for the drop they provide and price you pay, but there are much better options out there.

If I lower my cobalt ss 1.9 inches all the way around, do you think I would rub or scrape? I'm looking at M2 Springs by the way.

KYB Excel-G Struts and shocks w/ Tein Springs and ZZP Mounts. 225/45/18 Tires. I was very impressed with the KYB/Tein set up which I must say is equal if not better than my old stock FE5 set up and the drop is nice.

jg123boss

I have canuck motorsports springs with KYB struts and shocks which are the same as fe5 .

The KYB's are not the same as the FE5 struts and shocks...

They are closer to the FE3's.
