164 suspension upgrade advice wanted

I'm after some advice about upgrading the suspension on my '95 24v Super, specifically, getting rid of the "arse-up" stance that Supers seem to have. However, I don't want to ruin the ride too much, as it's already quite hard (I'm running 17" rims with 215/45 Falken tyres).
I've got a couple of options in mind:
1 Buy the Koni/B+G spring set from Alfissimo

2 Try some KYB shocks/B+G/H&R/Eibach springs

3 Replace the rear springs with ones from a Cloverleaf, which I believe are shorter.

Any advice would be much appreciated.

personally i have always liked koni's so imho i would go for option 1..

Not any use to you, but just mentioning. I have KYB shocks, and I assumed they were budget as they're the cheapest shocks I could get for my 164. (£53 each as opposed to £135 each from kwikfit). They are a lot firmer than the originals, but I'm happy with them.
