i don't have the Illuminas i have the AGX, but either way i would go with H&R springs, they ride SOOO nice compared to shitty coilovers. trust me you DONT want coilovers all they do is cause trouble. H&R ALL THE WAY!!! i've got thier "race" [3.5F/3.0R i think] springs it's a perfect drop, front and rear tires are just tucked behind the fender it looks dope. btw i have a 94 accord 2dr.... lemme know where you go
