Exactly. You CANNOT put a hardshell fixed back seat in a car w/o a rollbar and stay safe, there's no recliner to break and due to the high bolsters you can't 'duck' out of it, not to mention the 3pt belts won't really fit you snug like they are suppose to.

No. There is no 'progression'. They must ALL be done at once. Here's why,
Roll Bar only, your stock seats/belts won't contain you enough in the event on a rollover and you will end up hitting the bars and crushing your skull. The stock recliner seats also could lay back, causing it to fold into the harnessbar breaking your back.
Seats+Rollbar, The stock 3pt belts CANNOT hold you in place in the event of an accident and prevent you from sliding out of the seat, due to the higher than stock sides the belts can't tighten up around your waist and in the event of a rollover the stock belts won't keep your head and neck away from the main hoop.
Seats+Rollbar+Betls, Now you are contained, you won't slide out of the seat and you won't hit your head on the main hoop when you roll, nor will the roof crush you when you land on it.
For HPDE1+2, I HIGHLY suggest sticking with the stock equiptment if you are not prepared to do all 3 at once. The stock stuff was designed to protect you as a system, the same way the Rollbar/Seats/Harnesses is, when you start to change one part of the system, you make another part ineffective. I can't tell you how many cars I saw on grid in HPDE3/4 this weekend with only a harnees and no rollbar/seat or rollbar only, I just shook my head and pointed at the track.
