Can someone tell me if 12" rotors and later brake calipers will fit an '86 with stock 16" rims? I have relatively new tires and do not plan on changing them.
thanks

I'm a bit confused here. I think the stock brakes on an '86 use 12" rotors. So, I guess they fit with 16" stock rims. Maybe you are asking about upgrading to 13" rotors that came after I think '88 or so as the J55 option?
Yes, they are 12" rotors. You can upgrade to the J55 13" rotors with 2 piston calipers. Or, you can upgrade to the C5 calipers/rotors. For the best braking bang for the buck I think the C5 is the way you want to go. But, you will need to convert to 17" rims I think. If you do any NCCC racing events you will be put into Group III race prepared/altered frame, which means you need a full roll cage. Now, if you simply upgrade to the J55 system you can stay in your original class. Either way figure on about $1000 to get you started on your conversion, ballpark figure there.
