5 point harness? Who's got one?
I'm not looking for a full on roll cage, but I have seen a bar right behind the seats and then shoulder straps come through the openings in the competition seats. Just wondering who has a 5 point harness setup and didn't turn their interior into a full blown roll cage. I love the way a 5 point holds up in the seat but don't think it's possible without a roll bar behind the seats.

I know it’s been done. However in a roll over accident they are dangerous and difficult to get out of. Not worth the risk without a cage IMO.

Do a search and you’ll find lots of info. I copied my setup from the people here. I have a shark bar and under seat anchor from vetteworks and an anti-submarine harness from schroth. It is a 4 point harness with a 5th that can be added if neccissary. I also use a Simpson hybrid device which is like a hans device.
I haven’t crashed, so my advice isn’t worth much, but it seems like a stout setup. The hans device is somewhat controversial because if the roof collapsed you could become a load bearing column and get crushed. The B-pillar is incredibly stout in the C7, if it collapses, I think you were probably going to die anyway. I think you’re at much greater risk of a whiplash or vertebral injury than the roof collapsing, so I wear a Hans-type device. I am not 100% sure, but I believe they wear these devices at Spring Mountain.
I have never heard anyone say that a simple 4 or 5 point harness can be dangerous compared to a standard seatbelt and harnesses are highly recommended if you are doing a lot of HPDE.

I do a couple track days a year, but I actually find it more comfortable just daily driving or cruising around. I like the feeling of being secured tightly to the seat and having the belts over the shoulder I feel is more comfortable then across the chest. Probably the minority here but I'm more comfortable with an over the shoulder harness and lap belts.

I have a 6 pt and do not use the stock seats. I have racing seats with a lower seating position and higher belt cutouts. I have a BK bar. If you look at the angle between a shark bar and your shoulders, you will see that in the case of a sudden deceleration accident (not even a roll over), you will experience spinal compression forces because the angle of the belt exceeds 20 degrees. I consider that a more dangerous situation than just using a 3 pt and letting the airbag do its thing. The stock "competition" seats are not made to use 5 or 6 point harness unless the bar is VERY high, beyond anything I have seen on the market short of a full cage with custom attachment points, unless you are something like 5'6" or less.

If you are tall and can't move the seat forward very much then have a companion outside the car pull (using all of their weight) to get the belt tight and shove the slack into the retainer. When I take people for rides using the stock belts I pull their belt tight before I get in the car. Once they are screaming about the belt being too tight I close the door. The belts whether they are 3 point, 4 point, 5 point or 6 point can't get too tight.
