im lowered on Ksport GT springs and Kyb GR-2s. 2.5f 2.25r and i regret not buying Full Coilovers. i want to go lower.
but coilovers you can adjust, which i'm like 80% sure you're going to want after your springs settle. the lower you go can probably cause a little bouncy ride. most people regret buying springs and not coilovers. best bang for your buck is probably coilover sleeve/shock combo, it's a bit cheaper but next best thing before coilovers.
springs will give you a dinky drop but some people like their height on springs. they're cheaper also.
but ya check out the suspension review thread it'll help you out
