1g rear suspension...independent or not?

[sjgYFZ200]

Hey guys..i was looking at my hynes repair manual the other day and it says the suspension is "independent at all four corners". but if you go under the car and look, it doesnt look like any other kind of indepenednt ive seen before(rear)...so clear it up...what is it?

1g fwd is different then ALL of the other dsms. This also allows you to lower the back of a 1g fwd without camber problems

You mean AWD right? The FWDs 1Gs dont have an independent rear, but the AWDs do.

Saying that 1G FWD is different from all the other DSMs doesnt make sense, since the majority of 1Gs are FWD... so they aren't exactly "unique" in DSM terms.

having an irs(independant rear suspension) just means that the axles in back can twist in different ways a thte same time. <-kinda a bad analogy here let me try some pics.

a none irs rear or solid axle rear would be like this
\
\ when one side of the car is broughtup


a car equiped with irs could go like this

\__ so that only one side raises while the other side remains stationary

Imagine an old muscle car or look at newer model camaros. the rear axle it solid. Now look at the back of a new cobra or a c5 corvette the axles are independant of each other sorta like this.


solid axle rear

independant rear

please bare with me on the extreme angles of the "axles" i did what I could with only my kepboard.

Type slower and take a sec before you click post and that would have been 100% more readable.

As for the clunking... I think something's not right with your friend's car. Its not supposed to do that.

All 1g's have bad rear camber problems when lowered..


I wish my ### fwd was independent .. thats the main reason fwd has to have 2304509823 bends in their exhaust .. solid rear is stupid ..


Luke


Now food for thought .. could you convert a 1g fwd to independent rear .. using the independent rear from an awd 1g ..? .. now that would be pimp.. and if its already been done i wanna talk to who ever did it !

Luke, how are you have rear camber problems on a lowered 1G FWD. Camber is not adjustable or affected by lowering at all. The only issue regarding lower a 1G FWD rear suspension is the axle shifts more towards the passenger side of the car. Meaning that ythe wheel may be flush w/ the drivers side quarter panel, but stick out a bit on the passengers side.

thats when you get an adjustable panhard bar.

hmm .. thats prolly the stupidest thing ive ever heard .. almost every time you lower a car you have to re adjust the camber .. most of the time lowering it will will negatively camber the car // saying that its uneffected isnt entirely true ..

nah its brand new, nothign wrong. the new gto has a z06 350 in it making 350hp, the rear suspension bottoms out on hard downshift becaust the car squats.

the new gto is a z06 thats 1000 pounds lighter.

I have seen one or two pics of guys using those. Seems interesting, I may look into that in the future. I remember way back someone mentioning on the Digest back in the day.

Well you tell me what your camber currently is on the rear suspension of your 1G FWD. Go get it adjusted at any shop and see what they say. Better yet call RRE or DSS and ask them what they suggest for your rear camber. Maybe I am not reading you correctly but I don't think there is really anything you can do.
I can tell you up front on a 1G FWD 1/16"-1/32" toe out and 2.5* negative camber is a pretty good setup.
Once you find out what to do w/ the rear (sans an adjustable panhard rod as previously mentioned) please let me know.

ZO6s have 405hp. The GTO has the standard C5 Corvette motor. Also the curb weight on a 2004 GTO is 3770 lbs while the curb weight on a 2004 ZO6 is 3118.

 

[na90dsm]

wow then the dealer took my buddy for a ride man, he thinks its 1000 less then the z06 and has the motor from a z06, his also has the 6spd option and is purple.

There is talk that they are going to put the ZO6 405hp motor into the GTO. I don't know if its for 2005 model year or not. Even still it will be heavier than the Vette. Rule of thumb with GM performance cars, the Vette is the flagship no other lesser model will outperform it from the factory. Still the GTO is one sweet ride

 

[pc talon]

The 2005 GTO will have the standard engine that is going in the new C6. And yes they are adding hoodscoops and a exhaust with tips on both sides of the car (the current exhaust was already a dual exhaust but the gas tank forced them to be on the same side).

if you lower a 1g fwd and the back gets camber problems, theres something wrong with your car. i have adjustable coilovers on my 92 gst and can go from stock height to fully lowered with no camber problems. before you people post that someone else is wrong or what they said is stupid, you should do some research, or you end up looking like the idiot to the smarter people

also why is there talk of the gto in this thread? has nothing to do with dsms, go somewhere else.

Got any more info on that by chance?

Thanks, I thought I was the only one thinking that way.
Also what coilovers are you using, I have the DSS setup and love it.
