You might need to upgrade your springs and shocks integra ones for extra stiffness and higher springs rates. As for the brakes, I would go with brakes from a 94-01 integra gsr on all four corners. If you want to later you could go with AEM, brembo, willwood, baer, ect. brakes in the front. For the radiator, go with a gsr raidiator, or a fluidyne one made for a civic. The fluidyne is better but also much more expensive. The gsr one will do the job fine.
