The Vette IRS isn't that much of an issue compared to the others. I think there have been some getting into the low 11's or high 10's on in their Vettes. You're right the CTS-V and GTO are problems, but I can't see GM making this mistake. They are redoing the GTO as well. Maybe I'm overly optimistic...

You're from Evansville eh? I was born and raised in Evansville before moving to Chicago and now Indy... What part of town do you live on?

 

I'm from Newburgh and have been here my entire life. What part of Evansville are you from, school you graduated, etc? I graduated from Castle in 01 and USI 05. I also know a few who live up in Indy, most on the north side.

Um im afraid of change! altho the IRS is a great thing I'm affraid of change but i will be very happy to see how it does. I just dont want to work on it

 

I personally am not bias either way. GM is going todo what they want to do. If they put together a stripped down race version with a LRA then great. If not then great. The Camaro is still coming back as a RWD 8cyl sports car and it looks sweeeet!! For me that is plenty. Bless the aftermarket as they will swoop on in like with every other Camaro and make everyone happy.
I'm not knocking anyone else's opinion please don't mistake me...but this is mine..

 

If the L76 motor is offered, the aftermarket will be brimming with bolt on mods in no time, let alone stuff for the IRS if it ends up being wheel hop happy like the GTO's and 03/04 Cobras. I would love to be able to get an 09 Z28 as a daily driver and keep the SS as a street/strip car as it will be cammed pretty soon.

Actually you are talking more like 75 lbs over the LS7 for a S/C 6.2. Which isn't that much considering the power potential of that engine. And an IRS which is supposed to be heavier than its solid axle counterpart should still even out some of the weight distribution.
As for the IRS, I am all for it. I have seen some low 1.5 sixty foot times with nothing more than $500 aftermarket halfshafts and lowering springs. Since $500 is far less than the $2500 plus I have spent for my 12 bolt and accompanying (sp?) suspension upgrades I don't think thats a bad deal. What's killing the rears in the GTO/CTS-V is a combination of the weight of the car and relatively weak springs. From recent rumors and sheer speculation I just don't see the car weighing as much as either of those two cars (even with FI and IRS).
I think everyone here is getting all hyped up over specs that aren't even established yet. We don't know for certain if its going to add weight, cost, or complexity yet. This whole car is being built from a clean sheet of paper and with the attention that GM is directing towards weight savings I am sure they have already addressed these issues.

 

I hope you're right. The new CTS is 200 pounds heavier than the old one, though, which is not promising...almost 3900 pounds for the base model. When it originally came out in 2002, it weighed about 3500.

 

I'm ecstatic that we're getting an IRS.



Which describes pretty much every street, highway, autocross and road course I've been on.

 

Depends on the use. For those striclty running at the strip, a solid axle would be a better choice, but for about anything else, as long as the guts are solid, it will provide for a totally improved ride. Trust me, my cobra runs like a go-cart on steroids.

1991 RS-sold
1998 SS-sold
2004 KB Cobra aka: The Crusher ( I like bow ties, but she hauls the mail)
2010 top end Camaro

 

Let's hope they put a lot of attention into the details. IRS isn't necessarily immune to toe steer should you encounter a one-wheel bump or heave in the road. And if it can be felt on a low-mileage C5 during moderate to moderately hard cornering, there's room for improvement especially where a market segment that's assumed to be expecting greater sales is concerned.

The IRS will be a great thing. I have had both IRS/Solid axles, and my current O4 Cobra rides/handles way better than the solid axle cars I had. The Cobra needed upgraded bushings to handle the higher HP, and I'm not sure what the Vette's come stock with, or if they need stiffer bushings also? In the end, most people will enjoy the IRS.

 

I dig the IRS on the GTO. The GTO rides very well.

Honestly, I think that using a solid axle on the fifth gen would be a sad choice. Anything GM can do to make the Camaro ride better, and thus appeal to the masses, is fine by me. I hope GM can bring the Camaro to the market and sell each and every one.

 

X2!!!

The point I was going to make about "stock" LRA's and how you would need to spend 2500+ to make them a serious racer has already been made. I personally have went through 3 "stock" LRA and finally spent the $$$$ for a 9" and that 9" weighs a hell of alot more than the "stock" piece.

I cant wait to see the IRS and how it handles. you should make this thread a poll and ill put 100 bucks on it that the ppl that want IRS will out rank the ppl that want LRA's 4:1. GM's second smartest move when they designed the camaro was to put an IRS in it....

 

i would have to say i dont like it too much, but the vette has it and it works for them, but then again the gto had it too and look where their at.
