Yup, having the threads cut right into the body is very steep.

If I remember right, the Neon has springs around the struts on all four 
corners. If this is right you have it easy.

Give Ground Control a call. It was about $100 per corner for the sleaves, 
collars, upper perches, and springs of your choice, and you can slep them in 
in about an hour.

If you are lowering less than 2 inches like you said, you should not even 
have to chop off the old spring perches. On my old 83 Celica, I just slipped 
the threaded sleave right around the strut tube and let it rest on the stock 
perch. Done!! With the 7 inch long springs it sits lower than stock with it 
adjusted over halfway up the sleave. Dialed down it goes to over 2.5 inches 
below stock, but the strut does start to run out of travel. I also put in 
their camber plates at the same time, but the setup came with upper pearches 
to use stock upper mounts with the coil overs. 

The setup comes with Eibach ERS springs of your choice of rate and free 
length. If you need a few different ones, it is about $40 or so for another 
pair of springs. 

I had to do a bit of custom work on my old rear drive car, but I am sure they 
have done a Neon so it should be all off the shelf. I dealt with Tony at G.C. 
and he really knew his stuff and was very helpful in getting the right parts. 
They can also recomend the shortened strut inserts for seriously lowering 
your car, but then you get into chopping the stock perch off of the strut. 
Runing the spring down lower on the tube will allow a longer spring that can 
give better travel and less chance of hitting coil bind, BUT if it runs down 
past the tire, you will have to run much greater offset to get them to clear. 
On my car, the tire is only 3/8 inch off of the strut tube now, and the 
spring has to be at least 3/4 of an inch all the way around. The stock perch 
also acts as a splash gaurd in the wheel well, and when you go coil over, you 
may not be able to fit the nice boots around the strut rods. It gets real 
tight in there with 2.5 inch springs.
