So i have an 01 em2 and just put some d2s on my car last night and everything was going alright until we got to the rear. The only way me and two friends could figure out how to adjust the rear coilovers lower, were to screw out the bottom of the shock body. By doing so, this did lower the rear, but there is a gap betweet the spring and the top of the coilover until you drop the car, or i guess there is play in the spring until the car is dropped to the ground. This was the only way we could get them to lower the height, and it kind of seems ghetto, and im wondering if this is right or not? There is also a thumping noise in the back when i go over bumps which makes me think that this definatly isnt right. If anyone has ever installed d2s or knows any advice id really appreciate it, because as of now, my car is hardly drivable. Thanks

Yep they are like the BC's. Please read all of the clubrsx thread.

 

Thanks for that link, it helps, but im still confused.
Should there be play in the spring?
What is the easiest way to adjust the height properly?

 

its ok im confused too im midnightcivic from 7thgen..if u manage to adjust the height send me a pm..im stuck

 

ya like wise. ill let u know, and u let me know. hopefully ill know forsure how to do it in the next few days. i just need to get some air tools so i can take em off and figure it out.

 

Okay, so i installed some d2 rs coilovers on my 01 civic and the front is fine, the rear though isn't, atleast i don't think so. When i loosen the bottom two locks(gear looking things), the spring and height lowers, but there is a gap between the top of the spring and the tophat, and i really dont think this is right, but im not quite sure. I've been told theyre like BC's, but i don't quite understand. If someone could please inform me on this i'd really appreciate it. Thanks.

You already had an active thread about this issue. Somebody please merge.

 

you need to have preload. turn the bottom of the strut down as far as it goes. then adjust the spring perch up to make preload (the spring will begin to compress). once you have preload you can go back and turn the lower strut up if you need to to get your desired height. if you don't have preload, the strut may blow out sooner than it should, and the car will most likely ride like crap.

 

A fixed-stroke damper (such as the D2 coilovers) usually requires a certain amount of spring preload to maintain the pre-determined balance of compression and rebound travel. You are not supposed to set ride height by moving the spring perch with this type of coilover. If you attempt to do so, the damper will not be at the correct position in its stroke for the static ride height and you will risk topping out or bottoming out the piston - which will result in poor ride quality, erratic handling, and possibly damage the internals of the damper.

Read the instructions that came with the coilovers to determine how to properly set the preload by adjusting the spring perches.

Ride height is set by adjusting the lowest threaded ring which is located at the top edge of the lower mounting cup.

And yes, "suck" is a word I've used in the past to describe these dampers.
