If you are using HANS I prefer the 2" harness straps on the shoulder as they fit better on the device. Running a 6 point or 5 point is best (using a 6 point this weekend at VIR)

Justin, I had just a hoop for many years, then while doing the restoration extended the hoop to front and rear suspension points. Like you, this is for Auto-cross, DE's and hill climbs etc. Mark

Something else to consider but I didn't see mentioned:
"Equal restraints for driver and passenger".. No instructor wants to sit in a stock seat and 3pt belt when you have a race seat and harnesses. So, x2 when you replace your seats/harnesses. And as someone else mentioned, it doesn't have to be a "race" to be an accident.. DE.. High speed.. 1970s' weak sheet metal between you and impact. Safety is somewhat personal and you decide the minimum you want.. but realize that the insurance underwriting the events is what is driving the minimums standards up. Stock seat with harnesses was fine (well, allowed maybe is more accurate).. in the 1990s.. its not fine today. On my '76, the car had a Safety devices bolt in cage that was welded in. It also had stock seats. ugh. Pulled out the back pad, had a harness bar installed at the correct height and replaced the stock seats with some Kirkey Aluminum road race seats. Reasonably comfy. very nice when driving on the track. |

My only compliant was its kind of tall and rests on the rollbar with my long legs. Do you have any pictures of your install? Also did you just fabricate a harness bar into your roll hoop? |

By mounting to the floor, I got much more headroom clearance than I expected. Here are a few of the interior pics I could find: Attached image(s)
