Will integra suspension fit civic?
 

a freind of mine want to get rid of his koni reds, and some lowering spring (not sure what kind) off his integra sedan and i can get them durt cheep, will they fit an EK?

yes

There's issues. The rear LCA (or maybe just the bushing) on an EK is thinner, so you will need some strong washers to fill the space betweek then lower fork on the shock and the LCA Bushing.

I think the fronts are "plug-n-play".
