Caprice best year??

Yes a $20 bolt can help the 94-6 disc rears to work much better but it is a prime example of how 9C1 doesn't mean supercar like many want to believe.

Also it is drums that require high pressure and discs require large volume of fluid.
I have a close friend who was into 9C1s and settled on a civi 95 for his wife and the more he learns even he admits they are not that different.
As to leaving out the boxy cars, let's be honest they are so old as to not be the best choice for daily drivers anymore though their lighter weight could make them fun for play. Same basic chassis from 78-96 so you could use the Impala SS stuff.

I will also admit that I look at this stuff from the performance daily driver(20k+ a year) that is what I want, others will have differnt goals. For this the LT1 is the place to start with just a cam/springs and rockers inside the engine it dynoed 290rwhp the other day which is somewhere around 360 at the flywheel, I get low 18-23mph depending on the conditions and it has run 13.6 on street tires 13.2 on slicks and I can still use it to tow a small boat even on several hundred mile trips.

As far as boxies being too old for daily drivers, this seems like a purely subjective opinion. If you can find one that is in good shape, you can be richly rewarded. Believe me, I know from personal experience. Parts are cheaper cost wise, tend to require the same maintanance as regular cars, and the parts tend to last longer than cvilian cars.

As far as civilian/9c1 differences, like silicon212 said, by the '94-96 models, a lot of the features that were previously 9c1 only features had been incorporated into the civilian model were added to the civilian models every year. However, these 9c1 features remained 9c1 only features:

-Heavy duty frame
-100% silicon rubber hoses with stainless steel worm drive hose clamps (guaranteed for lifetime of the car, which adds to reliability)
-Specially calibrated transmission (generally with higher shift points than civilian model)
-8.5" ring gear rear axle
-radio bonding strap (keeps car body grounded together, helps with radio/CB equipment)
-Heavy duty seats
-Specially balanced drive shaft

To some people, these features may not matter; however, to some they can make all the difference in the world.
