i've heard there is a difference but i havent figured it out ...i know the rears are different but you can make them work in each other ...the shocks and spring seem to be the same and everything else matches up ....i been wondering the same thing as you .......

I thought you were interested only in the suspension parts.
In brakes you have different:
1 spindles or knuckles
2 calipers and pads
3 brake lines
4 rotors
Non of which are interchangable unless you swap the whole spindle assemblies. I think the hubs are the same, but I can't say for sure. It is popular for LT1 guys to swap over to the complete LS1 setup for better braking without it costing too much.
From 93-97 the F-bodies were offered with 15" rims on the V6 cars. This dictated a max rotor size of 11". The V8 cars had rear disc brakes while the V6 cars had drum rears.
During the makeover after 97 the F-bodies were offered with 16" rims minimum. This allowed the use of 12" rotors. GM decided to make all the brakes the same between the V6 and V8 cars which is dual piston aluminum floating calipers up front and single piston aluminum floating calipers in the rear.

My reply in regard to the spindle uprights happened because of the way they support the A-arms which in turn contain the strut. To my mind those components are suspension items that happen to also support the brake calipers. I certainly don't know for sure that they are considered part of the suspension but thought to take a chance. To me, being corrected is as good and better than being right.
Good info on the year and reason for the brake size changes BTW. Thanks....

The 4th gens don't use struts so I'm guessing you mean the spring and shock assembly. The 4th gens are actually a factory coilover design with unequal legnth double A-arms. Now if you look at the 3rd gen cars, they use one lower A-arm and a McPherson strut design.

I'm pretty sure the upper and lower A-arm and upper shock mounts are also the same from the 93-97 and 98-02 cars as well.

I usually don't continue this type of defense but the reason I refererred to the spring and shock assembly as a strut is because that is also how they are sometimes sold by name. Checking Summit's online store and even ebaymotors I am still seeing the shock absorber portion of the assembly referred to as a strut. Because the coil spring is held passively by the integral mount of the lower shock body is probably why you can find 4th generation fbody struts named as such. However, the official WikipediA definition includes "integral lateral support" to define a strut - Ala the McPherson strut. It's one of those definitions that has gotten lost in a fog of engineering changes so people can enter a parts store and still understand as well as be understood. I will try to use the proper names next time I change my shocks.
For now I will retire from the special Internet Olympics.

Not a problem for me. Statistically people are wrong 50% of the time. I run the average down for those who are right almost all of the time. However, not to raise your ire any further but look what a major manufacturer called the cheap-o shocks I've been putting on my cars.
