Is a wheel alignment mandatory after replacing shocks if camber bolts are seized?

Hey everyone,

I’m in a bit of a dilemma with my 2008 NC1 (101k km) here in Germany. My stock shocks are leaking and oily, meaning the car will fail the strict TÜV vehicle inspection this September.

I need to swap them out ASAP, and I’m deciding between a set of Bilstein B8s (to pair with my current -30mm Eibach springs) or switching to a proper coilover setup.

Here is the problem: A reputable MX-5 specialist took a look underneath and confirmed that almost all of my suspension bushings are shot and the alignment/camber bolts are completely seized inside the sleeves. They will most likely snap if anyone tries to turn them. A full bushing overhaul and high-end coilover setup was quoted at over €5k at the shop, which I currently cannot afford.

My question is: Is a wheel alignment absolutely mandatory right after installing new shocks or coilovers? If I just swap the dampers myself in my garage without touching the seized adjustment bolts, can I get away without an alignment just to pass the inspection, or will the geometry be completely ruined?
