I'm not sure what the stock ride height is for our 5th gens, but almost every car I've owned you want the ride slightly lower in the front and not the back. Unless this isn't true on the Preludes, my fear is that the previous owner lowered the rears on my car more than the front. Either that, or he swapped the GC coilovers front-to-back (someone told me this was a "cool" thing to do back in the day?)... that might explain the difference in ride height.

To me it just looks awkward to see my back sagging down so much. Almost like I'm moving and I stuffed everything I own in the trunk, ya know? Is this normal? I know I'm in need of new shocks, but the Ground Control coilovers are good. It shouldn't be sagging this much, should it?

I'm not sure what kind of measurements can help out in this, but I measured from the top of the rim to the beginning of the wheel well. As you can see there's quite a big difference from my front to rear...

 

Get coil overs

 

Um, I have coilovers... well, the hybrid Ground Control GCs. Not sure that's the problem. They are adjustable in height so either the back was adjusted lower, someone swapped the rears and fronts, or that's how a stock Prelude sits with the rear lower than the front??

 

I would just raise the back 1 cm and lower the front 1 cm. This is almost exactly how my car sits now and it bugs me too haha.

 

You have coilovers, just raise the rear. Not sure if you don't understand how they work or what, but this is a very simple fix.

Jack the rear of the car up.
Spin the perch up.
Make sure it's even on both sides.

 

just raise the rear a little this seems to happen with like all coilover sets for the 4th gens and 5th gens you can lower the back more than the fronts. It's normal the guy didn't mix anything up. Just raise the rears a bit.

 

Just to help since you haven't done this before: when adjusting the ride height, jack up the whole rear end of the car, not just one side.

 

Are the settings for height adjustment on the coilovers pre-set? I mean, are there designated 1/4" turns or clicks or anything like that so I am not like 1/8" higher on one side than the other? I know there has to be a trick here

 

There are no presets. Just adjust one side to where you like it, then measure from the bottom of the collar to the bottom of the sleeve. Then do the other side and measure to make sure they are even. It ain't hard.
