What makes it "safe" for Auto-X is that you're less-likely to roll the car than you are on a racetrack. I'm not sure I really buy that logic (I mean, how likely are you to roll a car *ever*? Either you ignore the low-probability danger or you don't).

Regardless of how you feel about all that (all safety is a tradeoff after all - you'd be safer not driving at all!), if you're going 4-point instead of 5/6-point, consider using Scroth's belts with the anti-submarining feature, e.g. SCHROTH RACING > Professional Racing Harnesses . It helps make up for the lack of 5/6-point attachment by letting your shoulder roll forward a bit to keep you from digging under the lap belt and getting really ****** up.

Agreed I am not too worried about roll over. I Ax and an airfield and there really no spots for me to even get the chance of rolling over.

I looked into the ASM belts but I'm not sure that's needed as well. What are the chances of me hitting something head on on the course? I would go with a 5 point be they don't work with stock seats :-(.

Well, you can extend that logic indefinitely. What are the chances of *anything* going wrong? Why even wear a helmet? It is important to reasonably protect yourself.

It's contradictory to say you'd use a 5-point if it weren't for the seats, but don't see the value in the Schroth ASM. The whole point of it is to provide the safety benefit of the 5th point, without a 5th point, for mostly-stock cars. Any collision from a frontal angle is going to benefit from having 5/6-point or ASM. You don't want your body trying to push under the lap belt (not that your body gets very far with that effort, but that allows the lap belt to ride up off your hips and into your gut, which can cause pretty severe internal injuries).

If you want to be rational about it, you could make a pseudo formula (sort of like the Drake Equation), that goes like: Value of Anti-Sub feature = Risk of major forward collision per year * value to me of having a functioning liver and/or not walking around with a colostomy bag for the rest of my life. Then compare that value to the additional cost of the ASM. I don't know about you, but for me that risk level would have to be insanely small to make it not worth it, because I put a lot of value on my hobby not crippling my internal organs.

Same sort of logic applies to multiplying out the tiny tiny chance of a rollover vs the value to you of not being paralyzed or killed one weekend. The odds may be tiny, but the loss is tremendous. It doesn't cost *that* much to stick a 4-point hoop system in a car and buy some level of protection.

I should have been more clear. If I were to add the harness bar and harness to the car it would be because its a cheap mod for autox. And due to the low risk of crashing I would rather get a cheap 4point harness or 5 point harness if it were possible since most can be had for $80 bucks or so. If I were to go with an ASM belt that is 300 bucks which cost more than the harness bar I would have to do more consideration as now I am looking at $500 for a small benefit. The price of the whole package would exceed the benefits that the harness would give me over my cglock.

I will have to think about it more and maybe just do control arms since they are not that expensive and would give me much more benefits to my time over the harness setup and I wont have to worry about safety.

Thnx for your input
