Quote »Anyways I want to put starion rims on my car. And my car is 4 lug what do I need to make it 5 lug? Mainly I want to know if I can use 84-89 300ZX Brakes and calipers to do it? [/quote]The short answer is you can't. The brakes are almost irrelevant to swapping to 5 lug hubs and I haven't heard of anyone attempting the brake swap with Z31 hardware.
The long answer is a bit different though.
Sounds, to me, like a good time to get new hubs since you'll get new wheel bearings with them. You S14 guys have it lucky when it comes to 5 lug conversions since you can just upgrade to the SE hubs (as previously stated).
You don't have to have bigger brakes to convert to 5 lug. You should just need 5 lug S14 rotors. Or you could have your current rotors redrilled.
As far as the Z31 brakes go I've never heard of anyone using them. They might work but then again they might not.
If you aren't tracking your car or driving it really hard often a new set of rotors (different people say different things concerning just using the stock rotors but I'd go with genuine Brembo rotors), some good pads (I run Pagid Blues on my M3 and they have plenty of bite), combined with some stainless lines, and DOT 5 brake fluid should equate to more braking power than you'll ever need on the street. Of course to really effect your stopping distances you'll need stickier tires.
The 26mm calipers clear more wheels than the 30mm calipers so if you're worried about fitment get the 26's.

Quote » The "26mm Aluminum" calipers were used ONLY on 1990 non-turbos. They used a 280mm x 26mm rotor.
The "30mm Aluminum" calipers were used on 1990 Twin-turbos and ALL 1991-1992.5 300ZX's (both turbo and non-turbo alike). They used a 280mm x 30mm rotor.
The "30mm Iron" calipers were used on ALL 1992.5-1996 300ZX's (both turbo and non-turbo alike). They also used the 280mm x 30mm rotor. [/quote]No mention of Z31 calipers. I'm sure that if they fit someone would have figured it out by now. Especially with as many people complaining about how hard it is to find Z32's in junkyards. If you really want to use Z31 calipers be prepared to fabricate mounting brackets.
EDIT: There is a good chance the Starion wheels won't clear Z brakes but Q45 brakes may still be an option. As far as I know the only major difference is the calliper width and that they may be down a piston compared to the Z brakes but I'm not to sure on the latter.
EDIT 2: You're going to need to make sure the starion wheels have the same lug pattern as the Nissan hubs. The hub bore may be to small as well. This information may be listed in Exar Kuns wheel faq over in the suspension forum but these wheels are a little obscure so you'll want to check and double check before commiting. They do look like nice wheels though. Should be interesting on an S14.
