I've gone to coilovers on a 1200 sedan.

Not gone too far with tuning the setup just yet. I'm currently in the planning stages of adopting the Ford Falcon's watts linkage to suit.

With 205/60x14 (perfectly centralised in wheel arch, I had to run a shortened AE86 Panhard rod.

With my current panhard rod setup, I still get some sideways movement as the diff swings through an arc, this results on slight rubbing on the inner guard at full bump, but I am running 205/55x15 these days.

I'm the only person I know with coilovers on a Sedan. I've seen it done on a couple of utes, where the flat underside means you can do almost anything...even go to IRS (But not seen anyone do that yet).
