I’ve done the same, my 80 was on its knees when purchased, so fitted longer / stiffer new springs and shocks (OME) from the off. They were rated as +110mm IIRC but of course that’s a measurement from stock height as-new. The effect was dramatic, more like 160mm!
Those have been on for 11 years now and obviously they have sagged, so recently I’ve “topped them up” as it were, with spacers. They work well and I believe them to be a “safe” option. I still get sufficient flex and the ride hasn’t been compromised. Maybe it’s not as firm as when the OME springs were first fitted, but that’s no bad thing.
I carry a fair bit of excess weight TBH, steel full-length roof rack, ARB steel bumpers, swing-out carrier at the rear, front winch, recovery gear, some tools and the like... total weight is circa 3.3 tones without driver/passengers, so they have to work hard.
