Coil spring mods

Do not, repeat, do not heat the springs. You'll take the temper out of them and then they'll break when stressed (like fully loaded and then you hit the kerb). That's bad.
You can cut the coils to do what you want, but try not to get them too hot while you're doing it. Cutting them is a pretty common trick in Lemons racing.

Droop straps.

Cannibalize a pair of old tie downs for the nylon straps and tie them in place to keep the suspension from traveling past the springs.

Or shorten the shock absorber rods

In the off-road world they're often called "suspension limit straps" and are used to prevent jacked-up 4x4 suspensions from going to full droop when hanging off a rock, etc. Here's a photo of an off-road one if it helps you to visualize what we're talking about:

Although I do really wonder how often we get these cars at full droop. FWD cars probably more than anything else since they'll tend to lift the inside rear wheel a lot of times. I guess maybe an inside front on a hard fast turn for a RWD car?

Maybe the solution is just to run only AWD Audis and Scoobs.

Not only on track, but when in the air for service the springs falling out of the perch can be a pain in the butt.

MOST cars have enough extra spring to stay seated with some trimmed, but in the case of your Saturn, I'd engineer something to limit droop.

....or go junkyard shopping for a stiff, tall spring from a larger vehicle that could be trimmed to do the task.

Our Lemons Caravan still had solidly seated springs after cutting two full coils. Mathematically it took our spring rate from around 110lb/in to 160lb/in.... with plenty of travel to spare.

I lowered a Saturn years ago and was before I had a welder I drilled.a hole in the strut spring perch and hose clamped it and worked fine . But if you got welder just Do heavy tack on there
