S14 Rear: ARP-100-7708 M12x1.5 .509 knurl 2.5" long. I've run these for years, but my open ended buldge seated lug nuts are flush with the top of the stud using 20mm spacers. The M12x1.5 pitch gives you a larger choice in lug nuts (although you'll need new ones since it's different than stock).
ARP-100-7713 might also work at 3.25" long. I'm not sure if the knurl tooth count is the same, though.
S14 Front:MOR-46160 7/ 16-20 in. x 2 7/ 8 in. Long, .560 in. Diameter Knurl. I've been running these for a while. They're not as strong and not nearly as rust resistant as the ARP studs, but they fit well. The big downside is the different thread pitch requiring different nuts than the rear, no matter what rear studs you run.
ARP-100-7717 might also work. 12mm x 1.5 x 3.0" long. The knurl is .005" oversized compared to stock, so they might not work without some reaming (9/16" reamer or drill might even work). I've heard a few people force fit them in, though. They're slightly longer than the Moroso studs, and they're a much more common thread pitch (pair up perfectly with ARP rears).
