just have a question about ep3 coilovers, would they be able to fit onto a 7th gen civic sedan? what adjustments would need to be made if any? any info would be great! cheers.
Will DC5/EP3 suspension fit my EM2/ES1 and vice versa
Yes, but it will require modification.
If you can find early EP3 stuff, then it should be a direct swap. Later years, Honda switched to 16mm strut bolts and larger tie rod ends.
To make a long story short this is what you will need to make things fit.
1) If you have a full coilover system with a front upper mount/camber plate, then all you will need is DC5/EP3 tie rod ends. You may or may not have trouble with the rear strut bolt. Sometimes they are bigger, sometimes they aren't.
2) If you have a full coilover system without a front upper mount/camber plate, then you will need DC5/EP3 tie rod ends and you need your upper mount from your stock suspension. It is not suggested that you use DC5/EP3 upper mounts.
3) Progressive springs (ie NOT coilover springs) WILL NOT FIT!! Technically they will fit, but the springs are designed for specific weight distributions and will look funny on your car.
4) Shocks from DC5/EP3 will fit if you keep your upper mounts and get new tie rod ends.
5) If you have a 2001-2002 EM2/ES1, then you probably will need to drill out your strut mount holes to 16mm. This is not an easy job and not recommended. It also is not recommended that you use your 14mm bolts on the 16mm holes because you run the risk of camber sliding.
6) Other misc DC5/EP3 parts may or may not fit. SOME front strut bars fit, ALL rear sway bars fit, SOME front sway bars fit, ALL rear lower tie bars fit, ALL trunk tie bars will fit, but HATCH tie bars will NOT fit (obviously because the 7thgen doesn't have a hatch).
