That IRS seems huge!

I think you found some of the "fat" on the beast......

Posted by: poSSum Jul 29 2008, 03:40 PM

I'm no engineer but for the life of me I don't understand how the rear can be better, lighter, cheaper, simpler (pick whichever ones are supposed to apply) than the double A-arms under the back of our Solstice.

Nice chunk of metal in the back suspension. </sarcasm>

Posted by: pknowles Jul 29 2008, 05:57 PM

I'm guessing that's how they got the weight distribution to be so good.

Posted by: cccbock Jul 29 2008, 06:21 PM

The drag guys will have that rear thing yanked out in two seconds. Anybody know the weight compared to our 10 bolt?

Whats that gizmo on the front end that looks like its attached to the PS lines...a cooler?

Single piston front brakes? Hope there is an upgrade on the SS.

W W nice suspension.

Posted by: BigEnos Jul 29 2008, 07:35 PM

All of the SS pics I've seen have featured 4-piston Brembos.

That rear upper A-arm sure does look like are front lower(bushings setup)! I wonder if it will have the same problems.

Posted by: roadracetransam Jul 29 2008, 08:27 PM

that is exactly the samething I thought

Posted by: John_D. Jul 29 2008, 10:09 PM

And 4 arms per wheel. I'm trying to visualize what's going to happen to toe through the suspension travel, and also how the 4 different arms can move at the same time without binding... I can't quite get it from the pictures.

The 3rd gen has a similar PS cooler that runs under the radiator support (below the support). Looks like they are doing the same approach here.

Actually, it looks like a hybrid of the 3rd and 4th gen front suspensions. We have coils on the shocks/struts like a 4th gen, but no upper a arms (I'm assuming this is considered a MacPherson strut design), larger than 3rd gen brakes, and it looks like it has hub assemblies from the 4th gen style setup. No more vertical castor bushing, it has "real" bushings that move the right direction (think 3rd gen). The top mount does not look like a camber plate. Either you'll adjust it at the shock bolts, or move the lower bushings around (like a 4th gen). Probably slots in the Kmember.

And, I think Ford designed the rear suspension. It really reminds me of Fords "drop in" mustang rear setup from the 99-ish cars.

Interesting. So far, I'm still not interested in one, but that could change when I see it and find out the final specs...

The more I learn about the 5th gen, the less interested I become.

Did you notice the length of the front sway endlinks/balljoints and how thin they are. I bet more robust endlinks will be necessary if the sway bar diameter is upgraded.

To me the rear seems overly complicated, with two many different pivot points, and I also notice that there is a vertical bushing in one of the upper mounts, gee that's just great!

However I will reserve final judgement only because I know that GM was supposed to have benchmarked the BMW 3 series rear and the Camaro's platform is identical to the current G8, which is so far, getting great reviews vs. the 3 series. However, I won't be the first person to buy one no matter how good the reviews. Someone else can be the Guinea pig

Posted by: BigEnos Jul 30 2008, 03:30 PM

By the way, the front suspension is nearly identical to my '07 'stang, and that was just a ripoff of an E36 M3. It's a good thing, though. It's simple and it works.

Posted by: ERVRCG Jul 30 2008, 05:23 PM

It looks like it has a virtual ball joint setup like on many Mercedes products and Chrysler LX/LC platforms. There's enough compliance in the bushings that it will not bind and still offer a supior ride. It's like moving the ball joint further out towards the wheel. It looks like there is some opportunities for bushings or bearings or a conversion kit to a single arm/ball joint on the rear lower.

It's hard to tell but it looks like the front strut setup might also have the virtual ball joint design. If this is the case there will be a lot of caster and wheel movement (relative to wheel well) fore-aft with steering input. A nice tuning setup when done properly for the street but will be a tuning nightmare for the track.

Actually, the front hubs look like FWD hubs like the Solstice has. Looking closely, I think I can see splines in the hole in the center. It's possible that the front and rear use the same hubs.

Posted by: Mean Green Z28 Jul 31 2008, 03:27 AM

looks like it's time for the aftermarket guys to make some nice billet stuff to replace the stamped steel links in the back

Posted by: Blainefab Jul 31 2008, 10:35 AM

How the heck do those front swaybar end links not buckle? Are there extensions down and forward? Goofy front springs will give stock spring classes fits. Travel with wide rubber may limit the length of coilover springs.

Rear looks like it has more room for fat tires, and coilovers. The IRS assembly bolts on in 4 places - those places on a 4th gen are subframes... Hmmm...

Posted by: marka Jul 31 2008, 05:09 PM

Howdy,

?? That doesn't look anything at all like an E36 front suspension. It looks like it has forward mounted "radius rods" or whatever they're called to resist front to back motion of the wheel vs. the L shaped lower control arm an E30/E36 used:

But maybe I'm missing something in the picture. Looks more like a 2nd gen MR2 to me...

Oh, and has anyone else noticed that the car has a guibo!?!?

Posted by: shortbus Jul 31 2008, 05:14 PM

When I clicked on the linek I saw the first pic and thought I was at a BMW forum. Did anyone else see the bmw-ish-ness? I had a mid 90's bmw and had flashbacks for a sec. heh. fox body front end maybe?

You won't be able to turn the front shocks upside down. I think the calipers were just the mock up, I don't think that car at any level gets single piston brakes. I noticed the sway bar end links too. There has got to be a better way to do that. On the other hand it looks like lowering and bump steer won't be as bad as a 4th gen.

The rear looks good. 4 bolts and removal.. if you have a 2 ton jack. I don't think it will be that heavy, it just looks massive, but it is all stamped steel. The drive shaft prop looks vette-ish.

Here's hoping for a good car.

Posted by: shortbus Jul 31 2008, 05:16 PM

I did I did. don't vettes have them too?

Posted by: BigEnos Jul 31 2008, 05:16 PM

I don't know about "doesn't look anything at all like an e36", but yep, two arms vs. one arm, my bad. I guess all Mac Struts look the same to me.

Posted by: BigEnos Jul 31 2008, 05:17 PM

They have torque tubes, dunno about guibos.

Posted by: shortbus Jul 31 2008, 05:24 PM

Yeah, Inside the torque tubes. I am sure of it. I see them laying around Danny Popp's place at McKluskys.

Posted by: ESPCamaro Jul 31 2008, 07:30 PM

Ha ha. Fuck guibo's

Posted by: ESPCamaro Jul 31 2008, 07:34 PM

Personally that rear suspension looks REALLY nice IMO......Hell take off the calipers and tie them up and undo the subfram bolts and driveshaft and drop the entire business in one shot....For any servicing etc.


Front. Meh. Nothing exciting. Then again nothing wrong either. Doesn't really look like my BMW, but a strut front end. Stiffer springs bigger bar and camber plates and your all set....


More important questions are how much will they weigh, and what size wheels?

Posted by: Eugenio_SS Jul 31 2008, 10:11 PM

wtf is a guibol ?

Posted by: ESPCamaro Jul 31 2008, 10:34 PM

A guibo is like a rubber flex coupling on a steering shaft. Only BIG and on the driveshaft of BMW's

Posted by: 4manracing Jul 31 2008, 11:39 PM

My wife has an 08 Charger R/T with virtually the same setup, not lots of adjustability. You move the whole crossmember to adjust uh...I'm not sure really, but that's what they did to set it at SRT specs. The car is a pig at #4132.....you can get back up on your chair now ! Overall, it does grunt the power down nicely if the computer doesn't shut you down (one clip of a wire to fix that one)
