Exactly. I'm running a leftover set of BC coils from a full coilover kit in the rear, cut springs in the front currently. I'm upgrading to a full BC Racing BR coilover kit this summer, but the ride quality and handling on cut springs is as to be expected:
Please don't do it
I race in SCCA and with the money I had to spend for a future engine swap, I was short for a full coilover kit. I didn't want to spend nearly the same for a Megan kit when BC is so much nicer, so I took a shortcut. Worst mistake ever, as I would've guessed. I've entered a few AutoX events and one circuit event with the Versa, but the only positive to the cut springs was center of gravity. Your OEM coils will still have the same spring rate from the factory, and with this lower ride height you're more likely to bottom out over just about anything.
My main point is this:
If you wholeheartedly intend to cut your springs, it's dangerous. If you don't cut from the bottom of the coil and line up the end coil with the one above it, it could slip while driving and create a huge hazard or even cause an accident. This also limits how much you can lower your car to segments of each coil, about 2" every additional rung. I stuck with just 2" in the front, I rub slightly with 17x9 wheels et25 with 45 profile tires. Every time I jack my car up, I have to drop a specific side before the other so I can be sure the springs seat properly.
Then there's the fact that your OEM shocks will go out MUCH faster, I wouldn't keep any car like this for more than a year. It can also create other mechanical problems. For my racing hobbies, the risks didn't outweigh the benefits and I knew what I was doing. For daily use? It most definitely wouldn't have been worth it. I haven't had my cut springs on Raven for a year yet like they are, and I don't plan to go that long.
It's a risky and dangerous short-term solution to lower your car that has to be done RIGHT or you could be in serious danger. I would save for coilovers, Megan even has an EZ Street series (blue) for around $650-750 if you want affordable coilovers. I don't want to sound hypocritical as I am on cut springs in the front myself temporarily, but take my word for it.
I regret it, and I wouldn't do it again.
