Brake rotors
Any suggestions on brake rotors for a 90 rs 5.0?

go to your local parts store and buy a set. are you wanting a preformance up grade? might help if you gave a little more info about what you had or wanted.

If you are looking for a stock replacement, just make sure you get the domestic ones. I made the mistake of trying to save a few bucks and went with the Korean made rotors and after only 5,000 miles they are already starting to shudder under heavy braking. I think the price difference was about $10 for each rotor so it is definitely worth it to go with the domestic ones.

Another question I have is that I have noticed while looking for rotors that there is a standard rotor and one for a performance brake package. How do I know which one I have. Im pretty sure it's the standard one but...

I got some cross drilled rotors from Powerstop I think through Jegs. They are a little thicker then the stock, but the same diameter as stock (not 1LE). They were about $60 or something, but that was a while ago.
It was easy to do to swap them. Just get some good axle greese and may want to get new bearings when you swap them. Don't forget that seal on the back too.

I heard that cross drilled rotors would not be good for me unless I did a lot of road racing or something. Said because there is not as much surface to work with. ??hmm??
Baer just started selling high performance rotors...if you've got the money I'd go for those. I need new rear rotors come spring and that's what I'll be slapping on.
And as far as that comment about less surface area goes, that's true, but there is such little less area that it only makes a marginal difference. The reason the rotors are crossdrilled is so that they will cool down quicker and reduce brake fade under hard braking or when doing alot of braking(driving fast on a windy road).

cross drilling also helps braking by letting surface gasses escape between the pad and rotor, actually allowing 'more' surface area because these gasses are like little air pockets between the two surfaces.
