It bolts to either side of the seat where the stock belt's are bolted and the 3rd point is bolted to the rear where the lap belt for the back seat would be and it goes over my roll bar so i would love to know how this is unsafe since i get my car teched at every race track i go to and they say nothing about the harnesses

i've already outlined in a previous post the tech behind submarining and spine compression forces. you either just don't understand or don't want to understand the information i shared. or maybe you just plain don't believe me on this one.. that's ok don't take my word for it, do the research yourself. its for your own safety, not mine

your harnesses passing tech doesn't prove the configuration is safe. rather it is proof that whatever sanctioning organization is running the race or lapping day is extremely lax about safety.

here is the rule book from national auto sport association (nasa), a large sanctioning body in the US. that holds HDPE, time trial, club race and other events

http://www.nasaproracing.com/rules/ccr.pdf

section 15.5 (page 71 in the pdf file) discusses the rules for driver restraints that are permissible at nasa events

note that your harness configuration would fail on the following points
15.5.1 : your harness is 4 point, and not 5, 6 or 7 point
15.5.6 : the mounting of the shoulder harness is below a 20 degree line from horizontal from your shoulders
15.5.8 : your are using a Y type strap that does not have individual mounting points for each shoulder strap

also note that the OE driver restraint system would pass the NASA tech

this is going to be my last safety related post on your thread. i don't want to 'spoil the mood' of you boys ogling the 'models'

its your safety in question not mine or anyone elses, so go ahead and continue using that configuration if you like.. but please don't continue to spread misinformation that that configuration is safe. its not.
