Ah okay, what do you mean by splining down the torsion bars and cutting the bump stops? Wouldn't it be easier just to get new shocks that are height adjustable? ( sorry if the shock but is irrelevant I'm still quite a bit or a noob on suspension bits)
Oh right so type r springs too okay. Yeah that would be great if 6n coilovers fitted as there's so much variety on coilover for 6n's
Thanks and regards

Yea EP3 Type-R springs fit and people on here did that before but I don't know if they just fitted stock ones OR had stock ones and cut them, OR had the lowering sporty ones OR had the sporty ones and cut those down even more.... You have to do more research on that.
Shocks aren't height adjustable mate, shocks are just struts filled with pressurized gas or oil and they just absorb bumps and prevent springs from decompressing too quickly making the ride bouncy and getting wheels off the ground when you drive over something
Springs are responsible for ride stiffness and height of the car. Height adjustability is only possible if you have got a coilover set where you have a threaded tube with two rings which springs sit on and you can move those rings up or down increasing or decreasing spring length (there's probably more scientific name for that) and pre load.
The whole trick when you lower a 3rd generation civic is to get as much shock travel as possible because they are quite short to begin with and when you drop the car the shock travel decreases even more. Bump stops are rubber or poly bits that sit on the shock body that prevent top mounts smashing the shocks up when you bottom out. obviously they take up a bit of travel so when you cut them in half you gain some of it back. You have to sacrifice some protection though. There are other ways to get some shock travel back when you deck the car. You can order extended top mounts from Chedda_j which make the shock leg start a bit higher up then stock which free's up some more travel. Other way is to drop the bottom of the shock lower in the knuckle, but to do so you have to get rid of brake line bracket, which you probably won't get away with on British MOT.
About the torsion bars, there's a write up about it somewhere but basically torsion bar is a kind of ermm... bar which works like a normal coil spring but instead compress down and go back up it twists in and out under load. You can lower your car with them by taking them out of their tubes which they lock into by little splines on both ends and then rotating them inwards and putting them back in. The only problem is that one of the splines is taller and slots into a deeper slot so you know which way around is it for stock height. You have to file the taller one off so it will go in after you have them rotated. Most people say that two splines down towards the center of the car on both sides and torsion bar nut all the way up is the best
I hope I've managed to explain that properly, sorry English isn't my first language
