Re: Brake Question: It's a good news/bad news thing
I have used plain (not slotted) RDA rotors for many years with no probs.
They should be available off eBay.
I think the larger brakes actually came in late '91
IMO, for normal street use if your OEM rubber control arm bushes look OK, keep them.
With shocks there are several options available for inserts, but the best if you can afford them would be Koni yellow adjustables. (I assume that you have the gland nut struts)
Also, make sure you check stuff like ball joints and rod ends to compliment your new brakes, and shocks.

Any advice you get from me may only be worth what you paid for it.
