Quote:Ok so i have a Y Type 3 point Harness. Its not the cheapest set but I didn't have a spot to mount a 4 point at the time and whos going to put a 5+ point harness in there regularly driven car. So bascailly ur saying any Y type or 4 point and 3 point or not safe then why do they sell them I just don't get it

so first off.. i think a 3 point type driver restraint IS "safe".. (the seatbelts that come on pretty much all modern cars is a 3 point type driver restraint)...

with the OE 3 point there is no spine compression risk (no straps going around your shoulder) and no submarine risk

an unmodified car with OE driver restraints would easily pass nasa tech

secondly, yes in my opinion, the 4 point design is inherently unsafe... (at least one sanctioning body appears to agree with me)

due to the strap configuration only the 4 point harness that has a submarine risk.. to my knowledge this schroth rallye harness is the only 4 point that does not have a submarine risk.. this is a key reason why this particular schroth harness is DOT approved for street use, and others are not. (however, that schroth appears to have a Y shoulder design.. and would still not pass nasa tech)

as to why 4 pt harnesses continue to be sold, to be perfectly honest i think it is because there is a group of people out there who prioritize the looks over performance, and a group of people who does not do adequate research before purchasing vehicle modifications.... i put 4 pt harnesses in the same category as strut tower bars, tein s tech springs, incorrect offset wheels and cheapo 'racing seats'.. parts that look and feel good but perform their intended function very poorly

in my opinion, the driver restraints (seat and seatbelt) should remain OE unless the user is prepared to spend the considerable amount of money on an aftermarket seat, harness (and mounting points) and cage

try the CG lock.. i used it when i had an integra but i don't find it necessary in my sube

Quote:Are you allowed to keep the 3point harness and do the "tug-n-twist" they teach at Auto-x school (and thus eliminate need for CG lock)?

DP.. yea you can keep the OE 3point harness.. (they are actually really safe).. for some reason i have never needed the 'twist' but i'm fairly sure it wouldn't be an issue
