There are a host of cars that now come with a 3 point and fixed bucket seats, including the almost every Porsche GTx car

A fixed bucket and oem safety equipment can be used if properly designed.

When thinking about safety you need to address the glaring problems, first! If say someone is too tall to fit under the oem roll over hoop then obviously that's the most dangerous solution. But if someone is going to run a non factory, roll bar, bucket seat, harness and aftermarket seatbelt - then they better use a hans or a containment seat - see what happens if there is a side impact.

If a person can safely fit under the factory roll over hoops, with a bucket, factory air bag and a 3 point harness - that's a pretty stout set of safety features. To increase your chances of survival definitely driver should wear a donut.

In general I've found the following caveats to consider when replacing factory equipment that has been designed and tested by people significantly smarter than most of the people gluing safety systems together based on information found on the internet.

- avoid 3 points going over the bolster for the lap belt; thread the 3 point through the lap belt bolster loop and use an appropriate length seatbelt extender
- avoid 4 points and 5 point harnesses
- use roll bar padding and/or helmet to avoid becoming a vegetable
- make sure to observe proper harness anchor point geometry
