Yeah ur right, I guess AMS doesnt know shit about KA's or anything...
Or u might of heard of some these brands:
Most of the exhaust/turbo stuff is Greddy, HKS, Tomei, Blitz
Engine stuff is Crower, JE, Arias, Carillo
ECU is AEM, JWT, Apexi
Radiator/FMIC/Oil Pans are ARC, Greddy, Koyo, Blitz
Clutch are ACT, Fidanza, Exedy, Cusco
LSD is Kaaz, Tomei, Cusco, Nismo, OS Giken
Brake Kits/Parts are Endless, Greddy, Stop Tech, Project Mu
Springs/Coilovers are Tein, Apexi, JIC, HKS, Tanabe
Suspension is Battle version, JIC, Stillen, Tein, Cusco, Kazama
Struts are Greddy, JIC, Tein, Cusco, Tanabe
All of these brands are big brands that make good shit. If they advertise with SCC then its not really like they need too cuz u know all these brands already.
Anyways, its meant to be used as a guide for the new people who start their first post like "so i just got this car, what should i buy to make it fast?" or handle better?" or cool it better?"
