2nd gen posi rear end??
i was just wondering how to tell if my 88 gxl has the posi rear end in it, someone told me all the gxl's had it and i'm pulling a rear end from an 86 gxl today from work and was just wondering if this is true or if theres a way to check on it short of going to a dealership and asking or something. hopefully i'll hear back before i leave this afternoon, thanx everyone.

All 86-88 GXl, unless theyve been changed, have LSD stock. 89-91 do not.
There should be a small metal tag hanging from the backside of the diff, on one of the fill/drain bolts that says something about LSD fluid. Also, if you jack up the back of the car and put the trans in N, rotating one wheel should make the other rotate the same way. IF it turns the opposite way, it is a standard open diffy. Rotating the driveshaft should make both wheels turn the same way also, on an LSD.

Please read the FAQ for FC at the top of this section, before posting as this question is covered there.
And as a note: Posi or Positraction is GMs name for a Limited Slip Differential (LSD). Calling a LSD a Posi, is like calling all refrigerators Kenmores.

There are a lot of cost cutting short cuts on the S5 cars.

How does just a normal standard diff compare for just driving around town and stuff VS the LSD? Do you really even notice a difference?

If you have LSD, both wheels will spin in the same direction at all times, unless it is badly screwed up. This is a rule.
IF you have an open diff, behavior can vary. They can spin in opposite directions, or only one can spin. Most cars are equipped with open diffs unless they're an s4 GXL or a turbo...the 88 GTU and 89-91 GTU-s are exceptions, but these are pretty rare cars, and their owners are usually aware of their LSD-possessing status.
