if you have a 6speed the rear end is always a problem with the irs but if its a auto you dont have to worry as much. the drive shaft is also a weak link in 6 speeds but plenty of people push em to the limit with no probs...
I am pushing 650rwhp and have not upgraded a thing. Now that is not to say it won't break in the future but it has held up for 20k miles.
If you plan on pushing serious power you will need stub to hub new driveshaft and pedders suspension. (not cheap)

^^^Agree in full, i feel on a 6 speed if you start modding on a LS1 it will be the clutch, All the GTo will wheel hop around like no other but throw some brag bags in the rear and that will help out. BMr makes great half shafts but i hope u dont mind spending some money there...

The weak points would be the clutch/converter/trans and then the suspension. The other weak point is you are only able to stuff a 275 in the rear without really have to mod the rear fenders a lot or get different wheels. Even then you can maybe get a 285 in there.
Other than that, these cars are pretty nice.

A wider (BFG/Goodyear) 295 will not fit. I have on 285/35/18 Goodyears and they are too tall. They fit width wise with the fender work and suspension I have done, but even with beating in the fender wells some they still bottom out. Not really worth it, just get some 255-275 DR's.

I dont get why people keep sayin the stock suspension sucks, unless your talkin about launching it at the track then yeah but thats not with the GTO was designed for, it woulda had a solid axle if they wanted a straight shooter. i love the way my 06 drives and handles, I mean the pedders suspension is better but there is nothing wrong with the stock GTO suspension. it handles better then most cars out there as it is.

The GT in GTO is for Grand Touring I agree that the GTO suspension and handling are pretty nice. I am not a dragster and use my car as a GT car. It's like a muscle car variation of a BMW M3. Although the handling is not as sharp as an M3 (very few cars are), it's still very good. Pontiac originally stole the GTO name from the 1962-64 Ferrari GTO (Gran Turismo Omologato--homologated meaning that enough had to be made to qualify it as a "production" car). But the GT part of the name is well deserved. Although I loved muscle cars in the 60s, I lean toward sports cars and own a 1966 Ferrari. The GTO is a great grand touring car, with power, handling, and a classy interior. It's also fun what some of you guys have done to tweak the engine and suspension. But it's a fine GT car the way it is, from the factory. And it has "street cred" with people who know & appreciate unique cars. (2004 Impulse Blue/blue int./M6/27,000 miles.)

I have stock suspension, tranny, clutch and rearend stuff... I have MT's 275s w/ cut fenders... and I launch anywhere from 4-5K rpms and never had a problem with wheel hop...

wheel hop is a very weird thing. some can't get rid of it no matter what they throw at it and some like you don't see it. it's more common than not and the M/Ts with you are probably the reason you don't see it. if the tire doesn't spin, the wheel doesn't hop.
The weak points are no room for a real tire, wheel hop/ saggy stock springs/ the stock shifter takes alittle getting used to, and the MFing little trunk but I still love my goat anyway.
