why in gods name hasnt chevy been able to develop an independant rear suspension setup for thier cars?
as much as i love cavaliers, especially mine, the only fault of the cars is the damn rear dead axle. (the only fault other then the faulty window motors maybe.)
but for years cavaliers have been made with solid rear axles. now with the realase of the cobalt, well the same thing rings-true. a supercharged car with recaros inside, yet a dead rear axle.
i dont mean to rant and rave, but can someone help me understand why chevy hasnt put IRS on thier cars? i mean we are in the year 2005....almost 2006...and still no IRS setups from chevy. whats going on?

note: in this thread im talking about the poor-mans chevy, not the few chevy super cars that have IRS.
i mean the cheap FWD cars, and even the cobalt (which is not cheap but FWD.)
damn not being able to edit

if you want irs so bad, do it your cav. theres a thread in here on how to do it

that is actually a good argument. but at the same time, you cant tell me chevy isnt already making PLENTY off thier new cobalt for example. how much would it really cost the company to put an IRS on thier cars?
i mean the ss 2006 non-s/c cobalt runs about 20k ,and the SC version is another 4k on top of that. they are basically charging 20k for a 4-cylinder FWD cavalier. for 20k, couldnt it of had IRS?
and i might end up doing the swap to mine in the future, but wouldnt it be nice if it was already done?

Uhh... yeah I can. Do a google search... they're not making squat off the Cobalt. It's replaced the Cavalier in keeping Chevy alive, it's a loss leader.
i think i have unraveled the mystery of why chevy doesnt put IRS on thier cars, thanks to mr. lenko.

if cost really is the issue, where did Dodge find the money in their bottom line to put IRS in the Neon?
Lifes too short to drink cheap beer.
because dodge isn't losing 2 billion dollars a quarter.

cause dodge didn't discontinue the nations number one selling vehicle
cause dodge didn't try to revam their whole line up at once
cause dodge has smarter people working for them then chevy
(Insert really cool picture of my car with some catchy name or slogan here)
if its a cost issue how come saturns came with irs on cheaper vehicle.
it wouldn't be but a few dollars more to lengthen 2 bars on a irs thats in production and weld it to our cars
First, car manufacture's are not going to build a extremely mass produce (200,000+) cars only to not make a dime. GM is dumb in some case, but not stupid.
Being that the Delta platform is old and really has not been really re-engineered since it saw light in 1991 in Europe and the rest of the world, I am not surprised the updates GM did to this platform in 2003 would consist of a all new suspension.
Being that the SS S/C is using parts from the Epsilon platform (hub, brakes, etc) GM could have atleast went a step further and adopted the aluminum 4-link IRS this time around. I mean, it is in the parts bin already.
Instead of GM building two separate rear suspension architecture they could have just built one.
More so the rear suspension on the Delta platform is an older design then the one found in the J. On the J (95-05) is a evolution of the one of found on the Delta which in turn is the same one found on the 1st gen 2nd gen Js. Yes, I know confusing.
The only reason today's Cobalt SS is competent is because GM spent some cash on the tuning Sach shocks, Pirelli/Dunlop Summer tires.
Personally I agree on the author, slap on the IRS with some good tuning on the lighter, longer wheelbased J and would be a hell of ride. Hell... in my case, just putting on the AGXs made a world of a difference already.

If you were to see how GM did with Saturn in the early 90s it was a masterpiece. Economically and engineering standpoint. Which is why Saturn being lowered priced had one of the most advanced compacts in the market. Consumers saw it as it peaked 300,000* sales in 1995.
Fast forward to today, Saturn is just a generic GM with it Springhill,TN plant closing. Sad indeed to see what Saturn was, to what has it come too.

Semper Fi SAINT. May you rest in peace.
skillz is right, there is no solid axle beam. there IS though a twist beam.

lets start an argument over twist or solid shall we? lol. we all know it flexes, atleast any of us that know anything about what is going on under there.

I couldn't find a pic (removed or installed) of a stock rear axle beam, so that is the modified and narrowed axle beam from Bagdfire's Sunfire. You get the idea though. That is a solid beam connecting together both sides of the suspension.
Its not a soild axel, its flexes and acts just like a sway bar.

now that is bs. where in the hell did you get "swaybar" from twist beam axle. it does help to keep the tire contact correct during hard cornering but it does not act as a swaybar which keeps your car from leaning over. no one even makes a real swaybar for our cars. if you want to see a real swaybar on an axle, go look at a vehicle with the new colarado truck frame (colarodo, h3, and im sure there are more on that same platform).
That was just the best example i could think of for way it is NOT a solid rear axle.

my bad, i just felt like going on a rant. im sure ill get about a million people arguing with me over the whole swaybar thing.
almost thought I would look under my car and find a chop saw.......
