So I was surprised to find that Chevy went with an IRS on this thing. I had a 2005 GTO putting down 450 at the wheels and far and away the IRS was the weak link. Couldn't hook without some serious suspension mods (and after rolling the fenders, and doing some cutting to get some decent rubber under it), then when it finally hooked, the rear grenaded. Couldn't take the power.
Any predictions as to how the rear on the Camaro is going to hold up as people start getting into the 500's and running 11's? Also, any idea how this thing hooks with some good drag radials, and stock suspension? Wondering if the gears, CV's, ets are as weak on this thing as they were on the GTO. I correct myself, the stock GTO underpinnings were great in stock form, with a stock car. Curious how the Camaro rear is going to hold up and hook.
Not really apple to apples, but I have a 2006 Dodge Charger R/T (5.7) W/IRS & W/drag radials I have run 12.0s on motor & 11.3s on juice. My 5.7 puts down 426 RWHP/460#RWTQ N/A, 555 RWHP on the juice.
Yes a solid axle is easier to hook up, but we (Charger, Magnum, 300C owners) are running as quick as high 9s for blown & sprayed strokers on the stock suspension W/upgraded halfshafts.
Good drag radials & a moderate stal convertor do the trick.
The weak link in our case has been the halfshaft spline @ the wheel hub.
After market halfshafts have cured that & the factory upgraded the outer spline in "09"
The old stcok halfshafts were good for low 12s/high 11s W/some care on the launch.
I have upgraded to an 8.8 Ford IRS setup from the Ford/Lincold SUVs.
It was a wash as far as $$$$ to install a 3.23 R&P, Aftermarket LSD & upgraded halfshafts in the Mercedes derived stock diff. The Ford unit makes replacemnt parts & upgrades much more cost effective.
So, in a nutshell, IRS does not automaticly prevent hooking up as long as the components can take the TQ.
The IRS on the Camaro is completely new, it's even a newer design than the G8's IRS.
While being very similar to the G8's (and based on that), it is stronger.
I'm quite glad that Chevy went with a IRS on the camaro. It provides a much smoother ride as well as much better handling on roadways which is where 95% of my driving occurs.
Obviously for the drag strip people are generally going to prefer a solid axle for maximum performance and strength, but hopefully the newly redesigned IRS on the camaro will prove to be more than adequate for the part time hot rodders. Anyone doing a pure Drag build are going to be rebuilding so much as it is that adding a solid rear supspension will just be par for the course.
I had it bad in the GTO. HAL QA1'a, BMR Drag Bags, every pedders bushing I could get under there... never completely eliminated it, especially when running Nitto drag radials aired down. Although it was a vast improvement. Every now and then it would hook like a cat on carpet.
ok got my first bit of wheel hop last night or atleast noticed it for the first time when I slammed 3rd gear on not such a smooth road and it was just a little bit not bad. Now yall have me worried I am going to blow it!!!!! LOL
