I know that the corvette IRS (independent rear suspension) will not go into an fbod w/o some in depth fabrication and $$$$, but does anyone know if a GTO IRS will go into an fbody? Or do the gto and corvette both use the same suspension? My goal is to put IRS in my 2000 WS6, if practical.

The GTO IRS is on the weak side, as has already been mentioned. The GTO guys would love to have a 12 bolt, which is really what you should consider. The 12 bolt is lighter than a 9 inch, and uses up less horsepower. Unless you're mostly a pure strip car with over 600 rwhp, the 12 bolt is a great choice. Bob

The GTO IRS is very similar in the center section to the 3rd gen 9 bolt. They are stonger than the 7.5/7.6, but just barely. Add in the IRS and there goes the extra strength.

GTO's do have bad wheel hop i used to work at a dealer and had to drive an '04 somewhere (wasn't a customers car). well i was driving and went WOT at a really slow roll like around maybe 20mph. And it felt as if the back tires were going to shoot right off the car. I easily prefer my 10 bolt, than the IRS that comes in the GTO.

But surely there is a reason for this? Regulations or budget perhaps? The ALMS/Rolex Sports Car Series cars use IRS (IIRC). And the C5R/C6R don't convert to solid axles.

Correct!! The Trans Am series rules forbade the use of IRS. In fact, they were required to use a Detroit Locker as well (over a tuned, better for their application, limited slip). That being said a soild rear axle CAN BE made to handle quite well.
